12 in 1 Air Quality Monitor Indoor- Portable Indoor Air Quality Meter for CO2, TVOC, PM2.5, PM1.0, PM10, Temperature, Humidity & Time Display【Dual Chip & High Accuracy】Air Quality Tester for Home

The 11-in-1 Air Quality Monitor has been an amazing addition to our home. It's easy to read yet small in size and shape, and it provides a wealth of information in a user-friendly format. My husband has issues with his breathing, and living in an environment with good air quality is critical to his health. This device provides real-time data regarding air particulates that can irritate the respiratory system in addition to displaying the temperature, humidity, and time. Additionally, it comes with a heavy-duty lithium battery and can be used both in and out of doors. This is a great monitor and we feel like we’ve hit the jackpot with it!

This air quality monitor is fantastic! It gives quick and clear readings on CO2, dust, and other pollutants, helping me keep my home safe. The CO2 alarm is super helpful, and the design looks great in any room. Easy to use, accurate, and portable—perfect for my home.Highly recommend for peace of mind.

Finally an air monitor that meets my standards! I love all the things this has to offer in one device instead of multiple monitors. The functionality is great and the Co2 monitor is a peace of mind feature that is so nice to have! I like that it’s of course portable so you can take it with you or just leave it at home. The connectivity is fine, no issues there, good value for the money, easy to use, accurate in the readings compared to what I already had. Highly recommend!

I have had this device for 1 week and have been testing it.First, the Pros: Good size, nice quality, well organized info, easy to read, and measures many things.When I received it it did not turn on. The instruction manual says if it doesn't turn on the first time it might need a charge. So I charged it for 40 minutes and went to try and turn it on - still wouldn't. I thought I was given a dud. But I kept it plugged in for a few more hours. Later the back of the unit was lit green - indicating a full charge - and it did turn on.After more use I have learned this only turns on at 100% charge. Not 99%, it must be 100% charged. Even if it is actively plugged in. I find this odd and have not encountered an electronic like this before.Once it is turned on you can unplug it and use it wirelessly. But you can't shut it off and on at will without the issue above. When I ran it unplugged continuously, the charge lasted about 36 hours before it shut itself off.I want an air quality monitoring device that I can also use in an emergency scenario where I may not have power for a couple weeks. If I could turn this on and off as needed to preserve battery and only use when I want to check the numbers, it would probably do the trick.But the odd charging configuration prevents this. I am still on the hunt for something that suits my needs.

Bought to measure air quality from 3D Printing fumes, and it kept reading "good" with no changes. to ensure it works I then subjected it to known terrible air quality- sanding dust, paint fumes- but no change. this thing's a dud.

Simple and effective. Plugged it in and it lit right up with environmental information. Helps me keep track of air quality and see when i actually need to change my air filters. It helps me stay a step ahead of my allergies. Love how it can run on its internal battery for travel use.

Well worth the price! Great quality, easy to use with a lots of great info to have on hand. Now i know when to cover myself or roll up my car windows ahead of time! Very nice portable Air Monitor at an Amazingly affordable price. Conveniently portable so it can be taken anywhere one may need to check conditions. The monitor reacts immediately to air changes. Great buy.

This is a cool little gadget for the price. We bought this to put in our baby's room to mostly monitor the humidity, but the other data provides a peace of mind that our baby is getting the best quality air. Not sure exactly how accurate everything is as I have nothing to compare it to, but the outputs seem logical and changes as airflow changes (i.e. when you blow on it). The unit has some weight to it and seems very sturdy and well built. I think this would be a good addition to anyone's home.
