Airthings View Plus, hands on: Smart but pricey air quality monitoring


  • Numerous sensors
  • Wi-fi sync
  • Extensive battery lifetime

  • Expensive
  • ePaper display screen flashes on updating

Given the sum of time individuals are paying within and worries about air pollution drifting in as a result of the window, an air quality monitor is a reassuring addition to the office environment. The most up-to-date Airthings monitor, View Furthermore, has much more sensors, furthermore an ePaper display screen to give you an instant look at with out you getting to pull out your cellular phone. It also utilizes Wi-Fi to sync info when your cellular phone is just not all around, supplying you the alternative to use it for automation.  

This additional operation adds up nevertheless: at $299/£249, this is one thing of an financial investment — in particular as some sensors have a confined lifespan. 


The Airthings Perspective Furthermore has a thorough set of air quality sensors.

Fitting in sensors for carbon dioxide (CO2), unstable natural and organic compounds (VOCs), particulate issue (PM1 and PM2.five), temperature, humidity and air pressure can make the Perspective Furthermore fairly a little bit larger than the Wave Furthermore, and about 3 instances the size of the dinky Wave Mini. It also can take 6 (non-rechargeable) AA batteries to power it, or you can plug it in to a USB-C charger. After 10 weeks of use, the battery was down to 76%, which is in line with the promised two years of battery lifetime. 

The ePaper screen on the front means that, although you’ll even now want the smartphone application or net dashboard to look at info in element, you can also see immediately if the two metrics you treatment most about are fantastic or negative. You can pick which two to see all the time, and waving your hand in front of the device triggers it to convert on an LED to give you an total crimson, yellow or inexperienced rating and flash as a result of all the measurements in sequence.

The fantastic information about the ePaper screen is that it’s simple on battery lifetime and is legible from a lot of angles. But it’s also the kind of ePaper that reveals former readings really faintly when you might be shut plenty of to wave your hand at the device — the screen looks good and very clear when you might be additional absent. You could also locate the not-fairly-instantaneous flash to black and back again as it updates every several minutes distracting if it’s in your eyeline. 

The Perspective Furthermore syncs above Wi-Fi instead than Bluetooth, while you even now will need to use a smartphone to set up the device and get it on to Wi-Fi in the initially spot (setup is the very same basic system as with former models). That means it can sync info when your cellular phone is just not nearby with the application functioning, so you can retain an eye on office environment temperatures right away to see the heating hasn’t been left on, or test in on air quality ahead of you get household, or just not have to keep in mind to convert on the application when you might be in range.  

The Perspective Furthermore can also act as a hub for other Airthings displays to sync as a result of instead than applying Bluetooth (we found through this critique than our Wave Mini hadn’t synced info in a couple of months), while you have to power it above USB-C for this to get the job done.

Comprehension your air quality 

The Perspective Furthermore is a single of the most thorough purchaser air quality displays on the current market. A lot of of the sensors are the very same as in the Wave Furthermore, while it does not have the mould sensor of the Wave Mini due to the fact humidity so large as to will need a mould monitor will degrade some of the other sensors too immediately. The carbon dioxide evaluate will be practical if you want to monitor air flow concentrations, although the new PM2.five sensor reveals you what most individuals assume of when they say ‘air pollution’: the little small particles that can bring about extended-phrase overall health challenges. 

The cellular phone application offers you a certain stage of historical info, and for much more you can dig into the charts on the Airthings dashboard in a net browser. 


Searching at the carbon dioxide concentrations above the training course of two times, you can see when much more individuals enter the space.

What you can do about the measurements depends on your situation and the bring about of the dilemma, but at minimum with this kind of info you can get a better picture of your air situation. Acquiring obtained a potent air filter (a Blueair model that statements to clear away particles as tiny as viruses) halfway as a result of screening the Perspective Furthermore, we could see that PM concentrations ended up normally reduce following it was set up in the office environment. Also, turning the air filter up would generally fall the PM stage immediately. But on times when exterior air pollution was large or the air filter was functioning on automatic, the PM stage would remain greater in the office environment. 

Opening the window in the office environment plainly can make a distinction to CO2 concentrations and VOCs (unstable natural and organic compounds from a wide range of sources such as plastic packaging). We saw a spike in VOCs the working day we hung up a string of battery-driven lights included in small plastic unicorns and, ironically, the working day we unpacked the air filter unit.  

Routinely getting the home windows open up in the spring experienced shown reduce CO2 and VOC concentrations (measured with the Wave Furthermore, which offers regular readings to the Perspective Furthermore) than those people we measured in the (considerably cold) late summer season and early autumn. CO2 concentrations also plainly observe office environment occupancy (from no-a single right away to two individuals and two cats through doing work several hours). We could also search at air quality indicators for the times the ink-jet printer was functioning and verify that it does not correlate to an increase in VOCs or particulate issue.  

Since the Wi-Fi relationship means it’s a much more persistently readily available info supply, the Perspective Furthermore also will get an API and an IFTTT relationship. The API is finding picked up by ecosystems like HomeAssistant and Homebridge, so you can join up numerous devices, most likely automating a humidifier, dehumidifier, fan or air filter when readings strike a certain stage.

As with the other Airthings displays, how helpful you locate the Perspective Furthermore depends on what challenges you have with your air quality and what you might be ready to do about them. If it’s too cold to open up a window (in particular with strength selling prices going up the way they are in the Uk), recognizing that the CO2 stage is greater than encouraged concentrations may possibly be a fret you can not do substantially about. But if you are ready to make alterations, this is a thorough, if expensive, alternative for monitoring down info to help you realize your air quality and see no matter if those people alterations increase it.
