## Description

BLATN Smart 128s Air Quality Monitor Indoor CO2 PM2.5 TVOC Meter Formaldehyde HCHO Detector VOCs Pollution AQI Tester PM1.0 PM10 Dust Particle Counter Data Logger Home: desertcart.com: Industrial & Scientific

Review: 10 months review - I have asthma and have this unit monitoring air quality in my living space 24/7 (connected to wall outlet via usb port adapter). Particles count seems to be accurate since it agrees with my air max 320 HEPA filter. VOCs sensor sensitive to any strong smell (food, paint, dish soap, etc). In order for unit to be accurate you need to leave it where you need to measure for at least an hour or so. Compared to other units on the market this is probably the best bang for the buck for instant readings. I also have an air wave sensor but that one seems to be better for longer term averages than instant readings. Battery life on unit is very short so I just keep it plugged in. Does not feel cheap, appears well built but user interface could use a refresh or update.

### ⭐⭐⭐ internal battery can’t be recharged or replaced
*by D***Y on August 28, 2025*

The device worked well initially, but after some time the battery completely died. Since the internal battery cannot be recharged or replaced, the device can no longer be turned on and is now completely non-operational. Very disappointing.
