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 am very satisfied with the product. After using it, I found that the TVOC value in some rooms of my home was high. I quickly strengthened ventilation and placed activated carbon. Sure enough, the value dropped a lot after a few days! It can detect multiple air indicators in real time. The data is intuitive and easy to understand. It really makes me feel safe!

Followed the instrctions (charged, put outside in open air for 30 min, then turned on for 2 min outside calibration). Brought it inside. Readings appeared ok. But then, at seemingly random times, it would beep (multiple beeps in rapid succession, and loud). No indication on the screen of why. A few parameters were in the "slightly poluted" range - nothing in the red. Nothing in the user manual about why it would beep or how you could disable this. Can't use this product when it randomly sounds off.

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!

The device has a simple design, is very easy to operate, and has a responsive touch screen. After using it for a while, I can clearly understand the air quality at home, especially the formaldehyde detection, which makes me feel at ease. Its real-time feedback also allows me to take timely measures to ensure the health of my family.

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!

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.
