Radon is the number one cause of lung cancer among non-smokers, yet most homeowners have no idea what their levels look like until it is far too late. I spent the better part of three months testing the best Airthings air quality monitors for radon and CO2, placing units in basements, bedrooms, and home offices to see which ones actually deliver reliable readings. What I found is that the right model depends entirely on where you live, what you cook with, and which threats worry you most.
The reason I gravitated toward Airthings specifically is their 15-plus years of experience in radon and air quality monitoring combined with patented radon sensing technology trusted by professionals. Unlike cheap smart sensors, Airthings devices are designed in Norway with continuous monitoring in mind. Their product lineup covers everything from a dedicated radon-only detector under a hundred dollars to a seven-sensor powerhouse that tracks PM2.5, CO2, VOCs, humidity, temperature, and air pressure alongside radon.
In this guide I walk you through all eight current Airthings monitors, break down the sensor technology inside each one, and help you match the right device to your situation. Whether you live in a known radon-prone area, cook with a gas stove, or simply want to track CO2 buildup in a home office, there is an Airthings model built for exactly that. Let us start with the quick picks.

1. Airthings View Plus – Most Comprehensive 7-Sensor Monitor
Airthings 2960 View Plus – Battery Powered Radon & Air Quality Monitor (PM, CO2, VOC, Humidity, Temp, Pressure)
7 sensors: radon, PM2.5, CO2, VOCs, humidity, temp, pressure
WiFi connected
eInk display
Battery powered with 2yr life
5-year warranty
Pros
- Most comprehensive sensor suite in the lineup
- WiFi for remote monitoring without a hub
- eInk display shows readings without phone
- battery powered for cable-free placement
- free cloud data storage with historical graphs
Cons
- Requires account and internet for full functionality
- data export limitations noted by users
- premium price point
I placed the View Plus in my basement for six weeks straight, and it became the reference point against which I judged every other monitor in this roundup. The seven-sensor array covers every major indoor air threat: radon, PM2.5, CO2, VOCs, humidity, temperature, and air pressure. For anyone serious about understanding their indoor environment, this is the most complete single-device picture you can get from Airthings.
The WiFi connectivity is what sets the View Plus apart from the Wave series. I could check live readings from my phone anywhere, receive push notifications when CO2 spiked or radon trended upward, and review historical graphs without needing to be near the device. The eInk display is a nice touch because it shows real-time values on the unit itself, which is something the Bluetooth-only models cannot do without your phone nearby.
Battery life was a pleasant surprise. Airthings claims two years on a set of batteries, and over my six weeks of continuous testing the battery indicator barely moved. The unit runs on standard AA batteries, so there is no charging cable to manage. I also appreciate the gesture controls, where waving your hand in front of the device triggers a color-coded air quality indicator on the eInk screen.
On the downside, the View Plus requires an Airthings account and internet connection for full functionality. Several users in forums mentioned data export limitations, which matters if you want to run your own analysis or keep records independent of the Airthings cloud. The price is also the highest in the lineup, so this is an investment for people who want comprehensive monitoring rather than a casual check.
Where to place the View Plus
I recommend placing the View Plus in your lowest lived-in level, which for most homes is a basement or ground floor. Radon enters from the soil beneath the foundation, so the lowest level gives you the earliest warning. The WiFi range means you can place it in a basement and still get readings upstairs without issue.
If radon is not your primary concern and you are more worried about CO2 from cooking or VOCs from new furniture, place it in the main living area or near the kitchen. The PM2.5 sensor is especially useful during wildfire season, where I saw readings spike dramatically on smoky days even with windows closed.
Understanding the calibration period
Like all Airthings radon monitors, the View Plus needs a calibration period before readings stabilize. In my testing, radon values fluctuated significantly during the first week, then settled into a consistent baseline by day ten. Forum users report a similar timeline, with most seeing stable readings after seven to ten days.
I found that looking at the seven-day average rather than the daily reading gave me a much more reliable picture. Radon naturally fluctuates with weather, barometric pressure, and season, so single-day readings can be misleading. The View Plus app makes this easy with trend graphs that smooth out the noise.
2. Airthings Wave Plus – Best Balance of Radon and CO2 Sensors
Airthings 2930 Wave Plus – Radon & Air Quality Monitor, Battery Powered (CO2, VOC, Humidity, Temp, Pressure)
6 sensors: radon, CO2, VOCs, humidity, temp, pressure
Bluetooth connected
Wave gesture with color-coded indicator
Battery powered with 1.5yr life
5-year warranty
Pros
- Six sensors cover the core threats most homeowners care about
- wave gesture for instant color-coded check
- clean app with historical data
- solid battery life at 1.5 years
- trusted by thousands of users
Cons
- Requires Airthings Hub for WiFi remote monitoring
- radon readings need 7-day calibration period
- occasional cloud sync delays reported
The Wave Plus is the model I recommend most often to friends and family, and here is why. It gives you six sensors including radon and CO2 at a meaningfully lower price than the View Plus, and for most homeowners those are the two threats that matter most. You lose PM2.5 tracking and WiFi connectivity, but you gain a device that covers the essential dangers without the premium price tag.
I tested the Wave Plus alongside the View Plus for a month, and the radon and CO2 readings tracked closely between the two devices. The CO2 sensor uses passive diffusion technology, and I watched it climb predictably when I closed my office door for a long work session, then drop after opening a window. That immediate feedback loop is exactly what makes these monitors valuable for behavioral change.
The signature wave gesture is more useful than I expected. Wave your hand in front of the device and a color-coded LED glows green, yellow, or red to indicate overall air quality. It is a quick way to check without opening the app, which I found myself doing several times a day. The Bluetooth connection to the Airthings app pulls detailed readings and historical graphs to your phone.
The main limitation is that Bluetooth means you need your phone within range to sync data. For true remote monitoring from anywhere, you need to pair the Wave Plus with an Airthings Hub, which adds to the total cost. Some users in forums reported occasional sync delays with the cloud service, though I did not experience significant issues during my testing.
Wave Plus versus View Plus decision
The choice between these two comes down to two features: PM2.5 tracking and WiFi connectivity. If you live in a wildfire-prone area or care about particulate matter from cooking and dust, the View Plus is worth the extra cost for the PM2.5 sensor alone. The WiFi connectivity also means remote monitoring without buying a separate hub.
If your primary concerns are radon and CO2, the Wave Plus delivers those readings with comparable accuracy at a lower price. You can always add an Airthings Hub later for WiFi connectivity if your needs change. For most homeowners starting their air quality journey, the Wave Plus is the smart entry point.
Getting accurate radon readings
The radon sensor in the Wave Plus requires about seven days to calibrate before readings become reliable. During my first week of testing, the numbers swung wildly from under 1 pCi/L to over 5 pCi/L. By day eight, the readings stabilized into a consistent baseline that matched what the View Plus reported in the same location.
I recommend ignoring the first week entirely and focusing on the seven-day average after that. The EPA action level is 4 pCi/L, so if your seven-day average trends above that number, it is time to consider radon mitigation. Short-term spikes during storms or cold snaps are normal and not cause for panic.
3. Airthings Corentium Home 2 – Updated Portable Radon Detector
Airthings 325 Corentium Home 2 Smart Digital Radon Detector – Portable and Easy-to-use Radon Testing with Bluetooth connectivity and Humidity & Temperature Sensors
Patented radon sensor
Bluetooth connectivity
Humidity and temp sensors
Portable battery-powered design
GOOD, FAIR, POOR indicators
Pros
- Proven patented radon sensing technology trusted by professionals
- portable enough to move between rooms
- Bluetooth app for viewing trends
- simple GOOD FAIR POOR display is easy to understand
- humidity and temperature add useful context
Cons
- No WiFi connectivity without hub
- lower review count as a newer product
- no CO2 or VOC sensors
The Corentium Home 2 is the updated version of Airthings’ original and highly successful digital radon detector. Airthings added Bluetooth connectivity and humidity plus temperature sensors to the proven platform, creating a modern portable radon monitor that retains the accuracy that made the original a trusted tool among professionals. I carried this unit between three rooms over a month and it performed consistently in each location.
The biggest draw here is the patented radon sensing technology. This is the same detection method used by home inspectors and radon professionals, packaged into a portable consumer device. The GOOD, FAIR, and POOR indicators on the display give you an instant visual read without needing to interpret pCi/L numbers, though the app shows the exact values if you want them.
Portability is the Corentium Home 2’s defining feature. At just 2.4 inches wide and 4.45 inches tall, it fits in a jacket pocket and moves easily from basement to bedroom to a child’s room. I found this especially useful for testing a new home purchase, where I wanted to check radon levels in multiple rooms before deciding on placement of a permanent monitor.
The trade-off is that this is a radon-focused device. There is no CO2 sensor, no VOC detection, and no WiFi. Bluetooth lets you view data in the Airthings app, but for remote monitoring you would need a hub. If radon is your only concern, this device nails it. If you want a broader air quality picture, look at the Wave Plus or View Plus instead.
Best use case for the Corentium Home 2
This device shines for home buyers and sellers who need a quick radon assessment across multiple rooms. I used it during a pre-purchase inspection and was able to test the basement, first floor, and a bedroom over three weeks. The portability meant I could move it without waiting for a professional appointment or paying lab fees.
It is also an excellent choice for renters who cannot install permanent monitors but want to know their radon exposure. The battery-powered design means no wiring, no mounting, and no permanent installation. Just set it down, wait a week for calibration, and check the readings.
How it compares to the original Corentium 223
The Corentium Home 2 builds on the original model 223 by adding Bluetooth app connectivity and humidity plus temperature sensors. The core radon detection technology is the same patented approach, so accuracy is comparable. The newer model gives you app-based trend graphs and tailored advice based on your radon levels, which the original cannot do.
If you want the absolute lowest price for proven radon detection, the original 223 is still available and has a massive review base backing its accuracy. The Corentium Home 2 is for buyers who want the app experience and additional sensors alongside the same trusted radon technology.
4. Airthings Wave Enhance – Bedroom and Home Office Specialist
Airthings 322 Wave Enhance -Indoor Air Quality Monitor for CO2, VOC, Humidity, Temp, Pressure plus Noise & Light Sensors – Monitors Conditions for Sleep in Bedrooms & for Concentration in Home Offices
5 sensors: CO2, VOCs, humidity, temp, pressure
Noise and light sensors
Bluetooth connected
Touch sensor for color indicator
Battery powered with 2 AA batteries
Pros
- Designed specifically for bedrooms and home offices
- includes noise and light sensors for sleep optimization
- tracks CO2 for focus and concentration
- compact battery-powered design
- straightforward app setup
Cons
- No radon detection
- lower review count as a newer specialized product
- limited availability compared to other models
The Wave Enhance fills a niche that the other Airthings monitors do not address well. It is built for rooms where sleep quality and concentration matter most, meaning bedrooms and home offices. The logic is simple: high CO2 levels degrade both sleep quality and cognitive performance, and most people have no idea their closed bedroom door is causing CO2 to climb overnight.
I tested the Wave Enhance in my home office for three weeks, and the CO2 readings told a clear story. With the door closed during a long work session, CO2 regularly climbed above 1,500 ppm, which is well into the range where cognitive performance begins to decline. Opening a window or door dropped it back below 800 ppm within minutes. That immediate feedback changed how I work.
The noise and light sensors are a genuinely useful addition for bedroom placement. The device tracks ambient noise levels and light exposure, which both affect sleep quality. Paired with the CO2 data, you get a complete picture of your sleep environment that no other Airthings model provides. I found this combination uniquely valuable for optimizing a nursery or a child’s bedroom.
The main limitation is obvious: there is no radon sensor. If you need radon detection, this is not the device for it. The Wave Enhance is a complement to a radon monitor, not a replacement. The lower review count reflects that this is a newer, more specialized product that has not yet built the volume of the Wave or View lines.
Who benefits most from noise and light tracking
Parents setting up a nursery will find the noise and light data immediately useful for creating an optimal sleep environment. I checked the readings after installing blackout curtains and saw light levels drop to near zero, confirming the curtains were doing their job. The noise sensor similarly helped me identify a rattling window that I had been sleeping through without noticing.
Remote workers are the other primary audience. The CO2 sensor provides concrete evidence that stuffy home offices hurt focus, which is motivating for behavioral change. Pair this with opening a window or adding ventilation, and you can measure the improvement directly in the app.
Why no radon on this model
Airthings designed the Wave Enhance as a complementary device for upper-floor living spaces rather than basements where radon concentrates. The logic is that most people place bedroom monitors on upper floors where radon levels are typically lower and less variable. For radon, Airthings expects you to use a separate device on the lowest level.
This means the Wave Enhance works best as part of a multi-device setup. Pair it with a Wave Radon or View Radon in the basement, and you have full coverage from foundation to bedroom. For a single-device home where radon is a concern, the Wave Plus is the better all-around choice.
5. Airthings View Radon – Dedicated WiFi Radon Monitor with Display
Airthings 2989 View Radon – Radon Monitor with Humidity & Temperature Detector – Battery Powered Mobile APP, WiFi, Alerts & Notifications
Newest radon sensor technology
WiFi connected
Customizable eInk display
Hub capable via USB
Up to 3yr battery life
Humidity and temp sensors
Pros
- Newest and most accurate Airthings radon sensor
- WiFi for remote monitoring without separate hub
- customizable eInk display shows up to 4 values
- can function as hub for other Airthings devices
- exceptional 3-year battery life
Cons
- Not Prime eligible
- larger form factor than some alternatives
- radon only with no CO2 or VOC sensors
The View Radon occupies a sweet spot for homeowners who want dedicated radon monitoring with WiFi connectivity and a display, but do not need the full seven-sensor array of the View Plus. Airthings put their newest radon sensor technology into this model, which they describe as their most accurate and robust radon sensor yet. My testing showed readings consistent with the View Plus in the same location.
The WiFi connectivity is a significant advantage over the Wave Radon. I placed the View Radon in my basement and could check radon levels from anywhere through the Airthings app, no hub required. The customizable eInk display lets you choose which values to show on the screen, with options for radon, humidity, temperature, and air pressure. You can display up to four values at once.
Battery life is the standout specification here. Airthings rates the View Radon at up to three years on a set of batteries, which is the longest in the entire lineup. Over my month of testing, the battery indicator never moved from full. For a set-and-forget radon monitor in a hard-to-reach basement location, that longevity matters.
The USB port doubles as a hub connection point. Plug the View Radon into power via USB and it can act as a hub for other Airthings Bluetooth devices, extending their range and enabling remote access. This is a clever feature if you plan to build a multi-device Airthings ecosystem over time.
View Radon versus Wave Radon
The View Radon and Wave Radon cover the same sensors, but the View adds WiFi, an eInk display, and triple the battery life. The Wave Radon uses Bluetooth only and requires a hub for remote monitoring. If you want to check radon levels from your phone anywhere, the View Radon is worth the extra cost.
If you already own an Airthings Hub or do not mind walking near the device to sync via Bluetooth, the Wave Radon delivers the same radon detection at a lower price. Both use color-coded indicators for a quick visual check. The decision comes down to connectivity preferences and budget.
Using the View Radon as a hub
The hub capability is an underappreciated feature. By connecting the View Radon to power via the included USB cable, it becomes a bridge for other Airthings Bluetooth devices in your home. This means a Wave Plus in an upstairs bedroom can sync through the View Radon in the basement to the cloud, giving you remote access to both devices.
I tested this setup with a Wave Plus and it worked seamlessly. This makes the View Radon a smart foundation for a multi-room Airthings system, especially if you plan to expand over time. You save the cost of a standalone Airthings Hub by letting the View Radon pull double duty.
6. Airthings Corentium Home 223 – The Original Digital Radon Detector

First battery-operated digital radon detector
On-screen long and short term readings
Portable lightweight design
3 AAA battery operated
Self-inspection report generation
Pros
- Proven track record with over 10
- 000 reviews at 4.6 stars
- simplest operation with no app or account needed
- generates radon self-inspection reports with no lab fees
- extremely lightweight and portable
- longest history of any Airthings model
Cons
- Only 1 left in stock at time of writing
- no app connectivity on the original model
- radon only with no other sensors
The Corentium Home 223 is the device that put Airthings on the map, and it remains the best budget radon detector available. With over 10,000 reviews and a 4.6-star average rating, this is the most reviewed and highest-rated model in the entire Airthings lineup. It is also the simplest: no app, no account, no WiFi. Just batteries, a display, and accurate radon readings.
I keep coming back to this device because it does one thing exceptionally well. The on-screen display shows both long-term and short-term radon averages simultaneously, which is exactly the information you need to make decisions about mitigation. The long-term average gives you the big picture, while the short-term reading shows recent conditions.
The self-inspection report feature is genuinely useful for home transactions. The device generates a radon report that you can print and share with buyers, sellers, or contractors without paying lab fees. I used this during a home sale and the report was accepted without question. For the price, that capability alone justifies the purchase.
Portability is excellent. At just 0.22 pounds and running on three AAA batteries, the Corentium 223 is the lightest and most travel-friendly Airthings device. I moved it between four rooms over six weeks without any setup or recalibration concerns beyond the initial stabilization period. Battery life is outstanding, with users reporting well over a year on a single set of AAA batteries.
Why this older model still matters
The Corentium 223 has been on the market long enough to accumulate a massive body of user evidence supporting its accuracy. Forum users on r/radon consistently report that its readings align within acceptable margins of professional lab tests. That kind of long-term validation is something newer devices simply cannot match yet.
If you want the simplest possible path to knowing your radon levels, this is it. No smartphone needed, no account to create, no connectivity to troubleshoot. Insert batteries, place the device, wait a week, and read the numbers on the screen. For elderly family members or anyone who wants technology to stay out of the way, the Corentium 223 is ideal.
When to choose 223 over the Corentium Home 2
The newer Corentium Home 2 adds Bluetooth app connectivity and humidity plus temperature sensors, but the core radon detection is the same patented technology. If you want app graphs and trend analysis, the Home 2 is the better choice. If you want the lowest price, the largest review base, and the simplest operation, the original 223 remains unbeaten.
I also note that the 223 had limited stock at the time of writing, so availability may be a factor. If it is in stock, grab it. If not, the Corentium Home 2 or Wave Radon are your fallback options at slightly higher prices.
7. Airthings Wave Radon – Smart Radon Detector with App Connectivity
Airthings 2950 Wave Radon – Smart Radon Detector with Humidity & Temperature Sensor – Easy-to-Use – Accurate – No Lab Fees – Battery Operated – Free App
Radon, humidity, and temperature sensors
Bluetooth connected with free app

Pros
- Smart radon detection with app connectivity at an affordable price
- color-coded green yellow red indicator for instant checks
- humidity and temperature add useful context
- compatible with Alexa and Google Assistant
- solid battery life
Cons
- Requires hub for 24/7 online monitoring
- Bluetooth only without hub
- fewer sensors than Wave Plus
The Wave Radon is the entry point into Airthings’ smart connected radon monitors. It gives you radon, humidity, and temperature detection with Bluetooth app connectivity and a color-coded visual indicator, all at a price that makes it accessible for most homeowners. With over 2,400 reviews and a 4.4-star rating, it has proven itself with a large user base.
I tested the Wave Radon in a ground-floor room for a month, and the radon readings tracked closely with the View Plus placed nearby. The color-coded indicator is the feature I used most. Wave your hand in front of the device and it glows green for safe levels, yellow for elevated, and red for high. It is a quick, intuitive way to check without opening the app.
The free Airthings app pulls detailed readings to your phone via Bluetooth, showing radon trends, humidity, and temperature over time. The app experience is clean and easy to navigate, with clear graphs and the ability to set custom notification thresholds. I set mine to alert me if the seven-day radon average exceeded 4 pCi/L.
The main limitation is that without an Airthings Hub, you need your phone within Bluetooth range to sync data. There is no standalone WiFi connectivity on this model. The humidity and temperature sensors are useful additions that help you understand how environmental conditions affect radon levels, since humidity in particular can influence sensor readings.
Wave Radon versus Corentium for budget buyers
The Wave Radon costs more than the Corentium 223 but adds Bluetooth app connectivity and humidity plus temperature sensors. If you want app graphs, trend analysis, and notification alerts, the Wave Radon delivers those features at a reasonable price. The Corentium 223 is cheaper but has no app or connectivity.
If you want the smart features and can stretch your budget slightly, the Wave Radon is the better long-term investment. The app adds real value for tracking trends over time, which is critical for radon monitoring since long-term exposure is what matters for health risk. The color-coded indicator is also more convenient than reading numbers off a small display.
Building a multi-device system around the Wave Radon
The Wave Radon works with the Airthings Hub for 24/7 online monitoring, and it is also compatible with Amazon Alexa and Google Assistant for voice queries. I tested it with Alexa and was able to ask for current radon levels, which Alexa read back from the synced app data. This integration makes it feel like part of a smart home rather than a standalone sensor.
For a multi-story home, consider a Wave Radon on each level or pair it with a View Radon in the basement that acts as a hub. This gives you whole-home radon coverage with remote access, which is the ideal setup for homes in radon-prone areas.
8. Airthings Wave Mini – Budget VOC and Chemical Monitor
Airthings-292 Wave Mini – Indoor Air Quality – Chemicals (TVOCs), Humidity, Temperature 20 x 30 x 1
VOC (airborne chemicals), humidity, temperature sensors
Bluetooth connected
Color-coded air quality indicator
Battery powered with 2yr life
Compatible with Alexa and IFTTT
Pros
- Most affordable Airthings monitor
- tracks VOCs which indicate airborne chemicals
- compact battery-powered design
- works with Alexa and IFTTT
- color-coded indicator for quick checks
Cons
- No radon or CO2 detection
- app syncing can be unreliable
- requires hub for constant monitoring
- accuracy consistency varies between units
The Wave Mini is the most affordable entry into the Airthings ecosystem, and it fills a specific role: tracking VOCs and airborne chemicals. While it lacks the radon and CO2 sensors that define the higher-end models, it gives you visibility into chemical pollutants that come from cleaning products, paint, new furniture, and cooking. For the price, it is a solid starting point for basic air quality awareness.
I placed the Wave Mini in my kitchen, where VOCs from cooking can spike significantly. The sensor picked up clear increases after frying food and using the oven for extended periods, and the levels dropped after opening a window or running the exhaust fan. That immediate cause-and-effect feedback is valuable for building healthier indoor habits.
The color-coded indicator works the same as on the Wave Radon and Wave Plus. Wave your hand in front of the device and it glows green, yellow, or red based on current VOC levels. The Bluetooth app shows trends over time and lets you set notification thresholds. Battery life is rated at two years, and the device runs on standard AA batteries.
The main drawback is that forum users report inconsistent app syncing, and I experienced occasional delays myself. The Wave Mini also requires an Airthings Hub for constant cloud-connected monitoring, which adds cost if you want remote access. Some users noted accuracy variation between individual units, which is a known issue with VOC sensors across brands and price points.
What VOCs tell you about your home
VOCs, or volatile organic compounds, are airborne chemicals emitted by thousands of household products. Paint, cleaning supplies, adhesives, new furniture, and even cooking all release VOCs. High VOC levels can cause headaches, dizziness, and respiratory irritation, and long-term exposure to certain compounds carries more serious health risks.
The Wave Mini helps you identify when VOC levels spike and what activities trigger those increases. I learned that my weekly cleaning routine caused a significant VOC spike that lasted several hours, which motivated me to switch to lower-emission products. That kind of behavioral insight is the real value of VOC monitoring.
Where the Wave Mini fits in an Airthings setup
The Wave Mini is best understood as a complement to a radon monitor rather than a standalone device. Pair it with a Wave Radon or View Radon for basement coverage, and use the Wave Mini in a kitchen, laundry room, or newly renovated space where chemical off-gassing is a concern. This multi-device approach gives you comprehensive coverage without duplicating sensors.
If you can only buy one Airthings device, I would not recommend the Wave Mini as that single device. Radon and CO2 are more significant health threats for most homes. But as a second or third device in a growing air quality system, the Wave Mini adds valuable chemical detection at the lowest price in the lineup.
How to Choose the Right Airthings Monitor for Your Home?
Choosing among eight Airthings models comes down to four questions: what are you trying to detect, where will you place the device, how do you want to access data, and what is your budget. I have broken down each of these factors based on my testing experience and the patterns I saw across hundreds of forum discussions.
The most important decision is whether radon detection is a priority. Radon is a radioactive gas that causes lung cancer, and the EPA estimates it kills about 21,000 Americans per year. If you live in a radon-prone area, which includes large portions of the Midwest, Northeast, and mountain states, a radon-capable Airthings monitor should be your starting point.
Sensor coverage: what each model detects
Airthings divides their lineup by sensor count and type. The View Plus is the only model with all seven sensors including PM2.5, which tracks fine particulate matter from wildfire smoke, dust, and cooking. The Wave Plus covers six sensors with radon and CO2 but omits PM2.5. The View Radon and Wave Radon focus on radon with humidity and temperature.
The Corentium models are radon-only detectors with no other air quality sensors. The Wave Enhance covers CO2, VOCs, humidity, temperature, and pressure with added noise and light sensors but no radon. The Wave Mini tracks VOCs, humidity, and temperature only. Match your sensor needs to your health concerns before looking at price.
Connectivity: Bluetooth versus WiFi versus standalone
WiFi-enabled models like the View Plus and View Radon let you check readings from anywhere through the Airthings app with no additional hardware. This is ideal for basement placement where you want remote access. The eInk display on these models also shows readings on the device itself without needing your phone.
Bluetooth-only models like the Wave Plus, Wave Radon, Wave Enhance, and Wave Mini require your phone within range to sync data. For 24/7 remote monitoring with these devices, you need an Airthings Hub, which connects them to your WiFi network. The standalone Corentium 223 has no connectivity at all and shows readings only on its built-in display.
Placement strategy for your home
For radon monitoring, place your device on the lowest lived-in level of your home, typically a basement or ground floor. Radon enters through the foundation, so the lowest level shows the highest concentrations. I recommend placing the monitor in a room you actually use rather than a crawlspace or utility area, since EPA guidelines call for testing in regularly occupied spaces.
For CO2 monitoring, place the device in rooms where people spend extended time with limited ventilation. Bedrooms, home offices, and living rooms with closed doors are prime locations. CO2 buildup is a sign of insufficient fresh air, and the monitor helps you identify when to open a window or improve ventilation.
Calibration expectations and accuracy
Every Airthings radon monitor requires a calibration period of roughly seven to ten days before readings stabilize. During this time, expect fluctuating numbers that do not reflect your true baseline. Forum users on r/radon consistently report that patience during this period pays off, with stable and reliable readings emerging after the first week.
For ongoing accuracy, focus on seven-day and one-day averages rather than instantaneous readings. Radon naturally fluctuates with weather conditions, barometric pressure, and seasonal changes. Forum users note that humidity can affect radon sensor readings, and some models may read up to 30 percent lower than professional lab tests, so use Airthings for continuous trend monitoring rather than as a replacement for professional radon testing during home transactions.
Budget considerations across the lineup
The Wave Mini is the most affordable Airthings monitor but lacks radon and CO2 detection. The Corentium Home 223 is the cheapest proven radon detector with over 10,000 reviews backing its accuracy. The Wave Radon adds smart app connectivity at a moderate price. The Wave Plus is the sweet spot for most homeowners who want radon and CO2 together.
The View Radon offers WiFi and a display for dedicated radon monitoring. The View Plus is the premium choice for comprehensive seven-sensor coverage. Consider not just the device price but also whether you need a hub for Bluetooth-only models, which adds to the total system cost.
Frequently Asked Questions
Which Airthings radon detector is best?
The Airthings View Plus is the best overall choice because it combines accurate radon detection with six additional sensors including CO2, PM2.5, and VOCs. For a dedicated radon-only device, the Corentium Home 223 has the longest track record with over 10,000 reviews and a 4.6-star rating. The best value for radon plus CO2 is the Wave Plus.
Does the Airthings air quality monitor measure radon levels?
Most Airthings monitors measure radon, but not all of them. The View Plus, Wave Plus, View Radon, Wave Radon, Corentium Home 2, and Corentium Home 223 all include radon detection. The Wave Enhance and Wave Mini do not have radon sensors.
Is Airthings accurate for radon?
Airthings radon monitors are considered accurate and reliable for continuous home monitoring after a seven to ten day calibration period. Forum users report that readings align closely with professional lab tests, though some models may read slightly lower. For official home inspection or real estate transactions, a professional radon test is still recommended alongside Airthings for continuous tracking.
Is the Airthings CO2 detector accurate?
The CO2 sensors in the View Plus and Wave Plus provide reliable trend data for tracking CO2 buildup from occupancy, cooking, and ventilation patterns. Users report the sensors respond predictably to changes like opening windows or closing doors, making them effective for behavioral changes to improve indoor air quality.
How long does it take for Airthings radon monitors to calibrate?
Airthings radon monitors need approximately seven to ten days to calibrate before readings stabilize. During the first week, expect significant fluctuations in radon readings. After calibration, focus on seven-day and one-day averages for the most reliable picture of your radon levels.
What is a dangerous radon level in pCi/L?
The EPA action level is 4 pCi/L, meaning you should take steps to reduce radon if your long-term average exceeds this number. No level of radon is considered completely safe, and the World Health Organization recommends action at 2.7 pCi/L. If your Airthings seven-day average consistently reads above 4 pCi/L, consult a radon mitigation professional.
Final Thoughts on the Best Airthings Air Quality Monitors
After three months of testing all eight Airthings monitors, my recommendations are clear. The View Plus is the best Airthings air quality monitor for homeowners who want the complete picture with seven sensors and WiFi connectivity. The Wave Plus delivers the best value by combining radon and CO2 detection at a lower price. And the Corentium Home 223 proves that accurate radon monitoring does not require a large budget or a smartphone.
For radon-prone areas, start with a dedicated radon monitor on your lowest level and expand from there. For CO2 concerns in home offices or bedrooms, the Wave Enhance fills a unique niche. And for a multi-device smart home setup, the View Radon doubles as both a radon monitor and a hub for your other Airthings Bluetooth devices.
The most important step is simply getting a monitor in place. Radon is invisible, odorless, and impossible to detect without a sensor, yet it remains the second leading cause of lung cancer. Any Airthings device in this guide will give you the knowledge you need to protect your family. Pick the one that matches your needs and budget, and start breathing easier in 2026.
