BREATHE Airmonitor Plus. Advanced 8-in-1 Portable Air Quality Meter & Monitor for Home and Office. Accurately Measures PM1.0, PM2.5, PM10, CO2, TVOC, Formaldehyde, Temperature & Humidity.

Works well and is portable. I can move it around from room to room. My wife suffers from a lung infection. I wanted to make sure the air was excellent. A dust remover helped.

The unit has a pretty straightforward interface and easy for anyone to set up. Easy to read display with many options to customize on the phone based app. Accuracy appears to be fairly sensitive, at least in terms of tracking change and proving historical records. I like it and glad I bought it, I didn’t know how bad indoor air quality got while I slept. Helps me make adjustments.

Clean display, well designed software, monitors all useful air quality metrics (except for radon.

I really like the air monitor. I’m hoping they improve the app though. Right now, I get many notifications whenever the PM or CO2 limit is reached whether that’s because the levels are increasing or decreasing. It'd be nice to also add the AQI to see how the air inside compares to outdoor air quality. It needs to stay plugged in 24/7 if you want continuous readings all day. Otherwise the battery life was not very long. Maybe a few hours. I like the display. If you have the screen sleep on, you have to walk up to it and wave at it to wake up the screen and then it’ll go back to sleep after a few minutes. You can also leave the screen on 24/7 and change the brightness levels on the app.

Got it the other day, So far seems pretty good we painted the other day so I know the TVOC would be a little higher than normal and it’s showing that so seems to be working good. Happy with my purchase
