Airthings View Plus and View RadonWhile I run an air purifier in my bedroom to reduce allergens, I can’t say I’ve been really concerned about my home’s overall air quality. Part of me thought since I switched from a gas furnace to electric heat I would never have an issue with carbon monoxide or a lot of dust in the air, but my calm attitude toward my air quality flew out the window after I plugged in the Airthings View Plus monitor and the Airthings View Radon monitor. I had no idea what was in my home’s air, and now that I know, I want to keep monitoring it long-term.

What is radon and why should I monitor it?

Radon is an odourless radioactive gas that’s present in all homes. It’s colourless and occurs naturally in small amounts. It becomes a problem if radon is trapped inside after entering a building through cracks in your foundation or other holes.

If it does become trapped and you routinely breathe it in, radon can cause lung cancer. While you can look on a radon map to see if radon levels are high in your area, the only way to know if you have radon in your home’s air is by testing it. That’s where Airthings View Plus and View Radon come in.

Setting up Airthings View Plus and View Radon air quality sensors

airthings view plus reviewAirthings View Plus and View Radon air quality sensors are small displays that use batteries and have a cord to connect to power. There is no hard wiring or complicated setup required. You can put the batteries in the display, plug it into power, and begin monitoring your home’s air quality.

The Airthings display will let you know what your home’s air quality or radon levels are at a glance, but you can pair the Airthings monitor with the Airthings app and customize your set up. You’ll download the app, tap to add an air quality monitor, and the app will find your device. They pair very easily and I connected both to my home network in just a few minutes. Once the monitors are connected to your home’s Wi-Fi network you can monitor your home’s air quality or radon levels from anywhere.

Testing Airthings air quality sensors

You can view your air quality and radon levels right on the display, so you don’t have to use the app unless you want to see what your air quality is like when you’re away or if you want to see detailed graphs and other data.

air quality airthings Airthings view radon sensor

I put the Airthings View Plus in my living room and the View Radon in my bedroom. With 7 sensors the View Plus can test for the following.

  • Radon: Odourless gas present in all homes
  • PM2.5: Particulate matter like dust, pollen, and spores that irritates lungs
  • CO2: Carbon dioxide in high quantities can indicate amount of recycled air (and circulating viruses in the air), cause drowsiness, and impact productivity
  • Humidity: High humidity can cause mold or spread viruses
  • VOC: Volatile Organic Compounds are chemicals from household products that can impact health over the long term
  • Air pressure: Affects radon levels and can cause body aches
  • Temperature: A look at your home’s temperature

The first thing I noticed when I started testing out the View Plus is that the air quality in my home isn’t that great. I’ve been in the middle of doing some long overdue maintenance on the floor and some walls, and I’ve been trying to clean up after to keep the dust low. I was also painting, because removing sections of the wall required a new coat of paint.

The Airthings View Plus picked up on the poor air quality right away, and it sent me a few alerts to my phone that the levels of PM 2.5 were too high. They are at 39 right now, but at one point they hit 186. That must have been when I was sanding the walls, sending dust into the air. After I painted, the VOC levels increased too. They are currently hovering at 149, but they hit 875 when I was painting. I had no clue the paint I was using had such high VOC.

Thankfully, the monitors have only shown very low levels of radon. The Airthings View Radon was in my bedroom, and I was pretty surprised to see that the radon level in my bedroom was higher than in my living room. It has hovered around 9 while the living room has stayed around 4. I’m happy the level is still low enough that there are no issues I need to fix.

Wave to light up Airthings air quality monitors

radon gas thresholdsThe Airthings View Plus and Airthings View Radon have very simple displays. You can’t tap them to scroll through all of your readings, but you can wave your hand in front of the display and it will flash a coloured light to indicate your current air quality. I waved my hand and a yellow light flashed to indicate that the air quality is fair. If I had good air quality the light would be green, and poor air quality would flash a red light.

The display will flash the light, scroll through your 3 main sensors, and then reset back to your main screen. The View Plus display is customizable and you can choose which 3 sensors you’d like to display on the screen. If you want to see PM 2.5, radon, and the temperature you can set it to show them on the display. All of your other data will still be available in the app.

I really appreciate having a visual indicator of my air quality right on the display. It helps me decide if I want to pull out my phone and take a look at what’s going on or see if there is a need to be concerned. The app also uses colour codes to show if your air quality is good, fair, or poor. The circle around the readout will be the colour it corresponds to, and that saves you time looking up whether 9 is a bad readout for radon.

Connects to your smart home assistant

You can connect your Airthings View Plus and Airthings View Radon to your Google Assistant or Alexa so you can use voice control. You can ask your assistant to let you know what the air quality is like in your living room or bedroom and they will tell you without you needing to open the app or walk past the display.

Should you choose Airthings View Plus and Airthings View Radon sensors?

airthings view radon air qualityI had no idea I had such poor air quality in my home, and I’d love to see what Airthings thinks after the sensors are fully calibrated. It takes 30 days of monitoring until they are, so I’ll have to wait and see what the next few days bring.

Both Airthings View Plus and Airthings View Radon are easy to use and make it very simple to see what your air quality is like. I’m really impressed with the readouts on the display, and I love being able to pull out my phone and see detailed information. Now that I’m aware I’ll make changes to improve the air quality and I’ll be moving my air purifier into the living room to see if that helps. I’m also going to choose low-VOC paint from now on because that sensor spiked when I was painting.

Both Airthings monitors really do provide peace of mind. Now that I know I could have radon, I can’t imagine not monitoring for it. The radon map showed higher-than-average levels of radon in my area, so it’s better to keep an eye on it in case something changes.

You can find Airthings View Plus and Airthings View Radon monitors for your home online at Best Buy.

  1. I would put the Airthings View Plus Air Quality Monitor in the upstairs hallway and the Airthings View Smart Radon Monitor in the basement.

  2. I would put the View Radon monitor in the basement furnace room, and the View Plus monitor upstairs in the living room, kitchen or hallway.

  3. I’d put the radon detector in my basement and the air quality monitor in my bedroom. I wasn’t aware of these products, they are really interesting.

  4. I would definitely place the Radon detection unit in our basement. We have a large basement, with many nooks and crannies that don’t get much air flow, I’m afraid. Our home was also built more than 100 years ago. We have recently turned the basement into our family rec and gaming room and I would really love to know Radon levels for the health of children and ourselves.
    I would put the multi-sensor up on the upper level in our children’s bedroom.

  5. I would place one in our bedroom and one in our living room. They are the two rooms we spend the most time in and are in two parts of the house that were built at different times so it would be a very good range of readings for us.

  6. Wbike the suggested livingroom and bedroom hallway does seem reasonable for me it would be the dining room and bedroom hallway as we tend to hang out there more.

  7. I would put it in the basement as our home is over 100 years old so am curious as to what the levels are down there. And I would place the 2nd one in the upstairs living room as we have a tenant and would like to see what the level is for them too.
