14-in-1 Air Quality Monitor Indoor with Beep Alarm, 6 AQI Air Detector with PM1.0|PM2.5|PM10|HCHO|TVOC|AQI|Temperature|Humidity|Time for Home, Hotel, Office, Car, Battery Powered

I've been very happy with this new air quality monitor. It is relatively small in size, think old school alarm clock, but it has tons of features. Setup is super easy and then you just need to turn it on and after about two minutes of calibrating it gives constant air quality readings.It is powered by a rechargeable battery that lasts a very long time. Recharging is down with a usb c cable. If you want to know more about the air you breathe I'd recommend this device.

Just a few months into using it, the thermostat and humidity sensor has failed. The thermostat is reading -45C And humidity is reading 00. Too bad it's too late to return it, but it is clearly defective.

I purchased this for my daughter in Oregon.She is using it. The battery is fully charged, but when she went to unplug it to take in the other room, it just shut off. She asked me if it has to stay plugged in, so, I tried to reach out to the seller on 12/28/24., they responded by saying it best to stay plugged in.She is looking for a better one than this.Update 1/15/25:After the review, I got they emailed me on 1/14/25.I sent a link to my daughter so she can return the product back. The problem is a faulty battery. Your supposed to charge, and be able to unplug, so, you can take it in another room.She sent it back. Since is is in the middle of moving she isn't going to get another monitor until she is settled in her new place.Only 2 stars for faulty battery.

This monitor is easy to read, although I did have to read through the instructions to see what all the readings indicated. I tested it against a few other gauges for temp, humidity and it seems to be accurate. I don't have any other monitors for air quality so can't vouch for the accuracy but since the others seem to be on target, I trust that air quality is accurate as well.It's a good monitor to have in a residential setting, especially in bedrooms, to monitor air quality. It's small and easy to read--great for ease of use.

It does not hold a charge, the thermostat is off by 3 degrees ，When I could not calibrate it using the instructions 。

The numbers on this monitor change constantly very hard to keep up with the quality of the air in the room I ended up returning product

Nice size, rich functions, easy to read and understand. The indexes are very accurate.

I have used many air quality monitors, and this one is the most convenient so far. Real-time detection, very short recognition time, easy to use and set up, and many functions
