11-in-1 Air Quality Monitor, Indoor CO2/VOC/AQI/PM2.5/Thermometer/Humidity Monitor, Portable Smart Air Quality Meters, Air Quality Tester for Home Office Outdoor, Battery Powered

I have children at home, and I am particularly concerned about the indoor air quality. This device can monitor multiple parameters at the same time, including PM2.5, temperature and humidity, VOC, etc. The results are accurate and updated quickly. The touch screen is very convenient to operate, and the displayed content is also very intuitive. It is worth buying!

Turned one on in my office room, after a few minutes it went all red beeping, showing all bad news. I started looking for a new house to rent! Turned the second one on and placed it in my bedroom, it showed all green, good-quality air. Then I took it to the office. two hours later one showed 30 and the second 800. Complete garbage.

Absolutely love this air quality monitor sooooo much! It provides instant, accurate readings for CO2, VOCs, AQI, PM2.5, temperature, and humidity. The portable design makes it perfect for home, office, and outdoor use. The battery-powered feature adds convenience, and the user-friendly interface makes setup a breeze. Real-time alerts ensure I stay informed about my environment. A must-have for anyone concerned about air quality!

I love it! It worked really well, I bought a new house last month and all furniture inside is brand new. I have a 2 year old kid so the methanal from the new furniture is my must concern. Luckily I bought this monitor, everything is clear, it also has time and temperature on it which is really helpful. I will definitely recommend to my friends!

After a proper calibration it seemed to work except my Particulates ratings were broken and unchanging. I learned I have high VOC and CO2 in my home. I've always used HEPA filters for asthma since young but HEPA doesn't clear those. I'm very upset no doctor ever told me about VOC and CO2, and about chronic low dose exposures. The best air purifiers or air scrubbers cost from $500 to $1000 or one has to blow in outside air or throw away many old things or store them in other places. I returned this for refund. I would so love to have a fully functional device like this, I'm tempted to buy another and hope I get a good one this time. Then I could try various methods to improve the air and test my results. Mine was shipped in a box also containing loose cans of beans bouncing around. This has delicate detectors in it, so order it when it will ship alone or combined only with soft lightweight items. Thanks for making this and I hope these detectors get better with time but also the broken ones add to overall pollution and waste so there is that to consider too if we have to be reborn here forever. Air is even more fundamental than water and food, and it is no easy feat now-a-days to obtain cleanliness in all three. There seems to be a metaphorical "evil wizard of oz" completely obsessed with poisoning EVERYTHING.

Some of the buttons on top broke easily. When I opened the device, each button component was lightly soldered at a 90 degree angle to the main board with no other support. Also the plastic button facade had a habit of getting jammed into the case even with a mild press. It wasn't hard to solder them back in, but I expected more for the $76 I paid at the time (it's currently $50 but that still seems too high).

This air quality monitor is very practical, especially for families with children and the elderly. It can monitor indoor and outdoor air quality in real time. The design is very simple and easy to operate, and you can check the air quality anytime and anywhere. The battery life is good and it can be used for a long time after being fully charged. I also have an air purifier installed at home. Now I can understand the purification effect through this monitor and adjust the air quality more scientifically.

Only real sensor whatever you want to call it, that seems to work accurately, is the temperature reading! This junk unit likes to sporadically jump to 999 and try to reset this it stays stuck showing all number eights. Even when I turned it off & waited approximately 15secs. dumb thing still showed all 8's when turned back on. I figured I would give it some time since taking the pictures for benefit of the doubt. Even brought this outside three times to try resetting for indoors...and well, let's just say done wasting anyone's time for whom ever is still reading this.....DON'T BUY IT!! Not even if someone double dog triple dog devil dog dares you..well if devil dogs are included ughh nope haha..anyway you get my point. OH!! and one more thing (actually two more things I could share but) these don't like to hold a charge OR take a charge..a full charge within 24hrs. More like 31.75hrs. The end.
