Know the air in your bedroom, nursery or office at a glance. Nine readings, including CO2, PM2.5, formaldehyde and TVOC, show on one color screen with an AQI bar.
All-in-one indoor air quality monitor showing CO2, PM2.5, PM10, formaldehyde, TVOC, temperature and humidity on one screen
- unknown indoor air quality
- elevated CO2 in closed rooms
- fine dust and particulate exposure
- formaldehyde and VOC off-gassing from furniture or new builds
Know what your indoor air is really breathing.
Stuffy rooms and unexplained headaches usually have a cause you cannot see. This monitor shows CO2, PM2.5, PM10, formaldehyde, TVOC, temperature and humidity live, so you know exactly where the air stands.
Every key indoor air reading, on one screen
- Formaldehyde and TVOC, seen
HCHO and TVOC sit beside CO2 and particulate readings. That catches off-gassing from new furniture, flooring and fresh paint, which CO2-only and PM-only meters never show.
- AQI at a glance
The color bar turns raw numbers into a good-to-poor status. You do not need to memorize units to know when to ventilate.
- USB-C power, no app
Plug in over USB-C and the screen wakes with readings. An angled stand tilts the display toward your eye line on a desk or nightstand.
From a stuffy guess to a clear number
The stuffy room you cannot explain
You wake up congested or headachy in a bedroom that looks spotless. Nothing is visible, so the cause stays a guess: the closed window, the dust, the new wardrobe.
What builds up unseen
CO2 climbs in a sealed room overnight. Fine dust settles and stirs again. New furniture and flooring release formaldehyde and VOCs for weeks. A single-metric meter catches only one of these.
Nine readings, one glance
Put the monitor on the nightstand or desk. CO2, PM2.5, PM10, HCHO, TVOC, temperature, humidity and time sit on one color screen, with an AQI bar that runs from good to poor. You see which number is off, then open a window or run a purifier.

Questions and answers
It is a consumer monitor built for trends and room-to-room comparison, not a lab instrument. Let it run a few minutes after power-on so readings settle, and judge by the pattern across hours.
Yes. Place it on a low shelf or nightstand out of the crib's reach, away from vents. The screen is bright, so angle it away from the bed in a dark room.
A single meter shows one number. This one adds PM10, formaldehyde, TVOC, temperature and humidity on the same screen, so you do not buy and place three devices.
The bar runs from good to poor. When it turns poor, check which reading is high, ventilate or run a purifier, then recheck after about 15 minutes.
No. It powers over USB-C and shows everything on its own screen. There is nothing to pair and no recurring fee.
You are paying for nine measurements and a large color screen in one body. Over time that replaces buying separate CO2, dust and formaldehyde testers, with no subscription cost.
