Good little Air Quality Monitor

We are enjoying our air quality monitor and like that it also shows PM2.5 and PM10 as well as the other measures. I gave it 4 stars as I would prefer that it worked via Bluetooth and not WiFi. Support staff are helpful. I find it's quite reliable when used beside the Aranet4.

CO2 inaccurate, unable to calibrate

The CO2 reading is inaccurate, reading about 30-40% lower than other CO2 monitors I've compared it against. The app has a way to calibrate it, but it appears disabled - it says that it needs to update the firmware to access that feature, but the app also says it's on the latest firmware. Frustrating.

Very unhappy

The device reads CO2 wildly differently than the other two readers I own (which match each other, and with reasonable readings). I have been unable to pair the device with my Pixel phone, even after downloading the dedicated app. The battery life on a full charge is crap.

Why Measuring PM2.5, tVOC, and CO2 Is So Important

PPM2.5: One of the biggest killers in the world, with 99% of population breathing dangerous levels. Even moderate levels are shown to cause cancer and heart disease. 

tVOC: Dangerous gases can irritate our organs and cause cancer

CO2: High CO2 levels can result in drowsiness, headaches, high blood pressure, and more.

*If levels are high, a combination of HEPA air purifiers and improved ventilation can help lower levels.air large text with an image to give focus to your chosen product, collection or blog post. Add details on availability, style or even provide a review.
