Air Quality Monitor Indoor,16-in-1 Smart Air Quality Tester with PM 2.5, CO2, TVOC, HCHO, PM1, AQI, PM10, Temperature & Humidity, Real Time Display, Battery Powered, for Home & Office

I am very happy with the air monitor. The multiple indicators have provided great insights into various issues related to the indoor or outdoor air and have helped me take measures to improve my home's air quality. I would recommend to everyone who wants to maintain a healthy environment in their home.

Works well, but the battery life is very disappointing. The battery seems to run out somewhere 4-6 hours. For all practical purposes, it is good only for "spot-checking."For full-time monitoring will require being plugged in all the time.

Nice color scheme. Easy to read numbers. Gives you all the air quality monitor readings you need. No batteries needed. It has sound features that alert you to any drops in healthy air around you.

Had some unwanted air quality issues lately due to damp and humidity and needed to monitor the indoor air quality and have this for almost a week now. I needed this chiefly to monitor PM 2.5 AND TOTAL VOLATILE ORGANIC COMPOUNDS. So far it seems to be working well and giving consistent results. It was fairly easy to get it going out of the box. Update: Stopped working within a month's time. Glad that happened within a month. It is still within the return window for me to be able to return it

I was really excited to receive this air quality monitor, especially getting it at the Black Friday discounted price. PROS: Nice display with all air quality readings including clock, temp and humidity, easy to setup, I like the USB-C cable. CONS: Inaccurate readings, The CO2 reading is always at around 400-420 even after cooking dinner with smells and smoke from oven. My AirGradient and Ambient Weather monitors were around 750-1100 during dinner time. Plus, the PM2.5 readings were very low and not accurate. The display is not bright enough even after the highest setting. No Wi-Fi or App. Also, very pricey for a non-brand name sensor. Needless to say, I was a bit disappointed and returned the unit.

This air quality monitor is everything I was looking for. Has all the types of air quality sensors I was looking for and all are very accurate. Love that it is rechargeable so I can move to different locations.

Functionality: Don't think its CO2 measurement is accurate. Battery life: It can only work for a few hours without the power plug-in.

bought this to use near my 3d printer, its clear and provides a variety of different readouts. it provides peace of mind knowing that im monitoring the offset from the different filaments im using
