Air Quality Monitor Indoor 5 in 1 Home Air Quality Tester for Home Air Quality Test Indoor Air Quality Meters HCHO/CO2/TVOC/Humidity Smart Air Quality Monitor with High Precision Air Quality Sensor

I discovered recently that I had high VOCs in one section of my house but the other sensor was slow and only displayed data on the iphone. I bought this but was skeptical since it was way lower that other sensors. It is FANTASTIC. First it has a very rapid response (outside it would go to zero and it responds quickly when I moved around). Then it was quite responsive to the source and helped me find that the source was a piece of fabric I had bought overseas. The readings went through the roofs when I draped the sensor in it. Now I removed it and the VOC levels in the house went down. I do environmental measurements for a living (bit not VOCs usualy) and this sensor is great to find the culprit emitters in your house.

This is a handy little portable air quality meter. It's about the size of a cellphone, although much thicker. It measures temperature, humidity, CO2 (carbon dioxide), HCHO (Formaldehyde), and TVOC (Total Volatile Organic Compounds). It's powered by a single 9V battery. Battery life is claimed to be 8 hours, but I saw the power level drop from 4 bars to 2 bars after less than an hour of use.I don't have a good way to verify its accuracy, but when I compare it to another air quality measurement device that I have, when both devices are side-by-side, this meter's CO2 measurement was 26% lower, while the humidity measurement was 13% higher. The other device measures VOC in parts per billion, while this device measures TVOC in mg per cubic meter, so not really an apples to apples comparison. I really can't say which device is more accurate, but even if this one is less accurate, it's close enough to at least provide a reasonable assessment of air quality.

good

As someone conscious about indoor air quality, I decided to try out the Indoor Air Quality Tester. While it does its job adequately, I found it to be rather average overall.The device provides basic readings of air quality metrics, such as PM2.5, PM10, temperature, and humidity. However, I found its accuracy to be somewhat inconsistent compared to other monitors I've used.Its design is functional but lacks any standout features or aesthetic appeal. The interface is straightforward, but the display could be more intuitive and user-friendly.While the Indoor Air Quality Tester serves its purpose as a budget-friendly option, there are certainly better alternatives available for those seeking more accurate readings and a better user experience.

During my SLA prints, I would notice a distinctly chemical residue build up at the back of my throat even though I wore a respirator during the print post processing. Since getting this device, I have discovered that the isopropyl alcohol cleaning phase was emitting high amounts of formaldehyde which was the time I assumed it was safe to take off my respirator. Highly recommended!

Purchased after new renovation. Very reliable.

Did not work

I needed it to constantly be on, this does not stay on for more than a few hours. Also without the backlight, it’s too dim to even see. Not a good product
