A compact pm2.5 air quality monitor with colour display for checking PM1.0, PM2.5, PM10, AQI, temperature and humidity in the spaces that matter most.
How to Use
- Place the monitor on a stable indoor surface or connect it in a car or hotel room using a suitable 5V USB power source.
- Switch on the device and allow it to warm up and stabilise for 3 to 10 minutes in the room you want to assess.
- Read the colour display to view PM1.0, PM2.5, PM10, AQI, temperature and humidity.
- For more consistent results, keep the air intake unobstructed and avoid placing the unit directly beside windows, fans or steam sources.
- Use the readings to guide ventilation, room choice or cleaning routines, especially after cooking, vacuuming or high-traffic periods.

What Our Customers Say
I bought this for our bedroom after seeing dust spikes during cleaning. The colour screen is very easy to understand and the PM2.5 reading changes quickly when we open the window.
Arrived quickly and was running in minutes. I use it as an air quality monitor for office use on my desk and it is much easier to read than the cheaper basic models I tried first.
From a practical health perspective, this is a helpful way to visualise indoor particulate trends at home. I like that it also shows temperature and humidity, which gives more context than particles alone.
Useful little unit for my flat and definitely more informative than expected. My only note is that it needs a USB power source, so I paired it with a power bank when moving it between rooms.
I was comparing this with a HOTKREM listing online and went with Airmeter because the product page was clearer about what it measures. Glad I did - it is neat, readable and very handy in the nursery.
I use it in the car and hotel rooms when travelling for work. It is compact and the AQI display is useful, though I usually wait a few minutes after moving it so the readings settle properly.
