We have handheld sensors we deploy in our home when there are fires. Are neighbor down the street has an exterior purple air that we use to get real time data.
This sensor sometimes matches our handheld but when it is left in one place it seems to settle down to no particles (it seems to have a minimum at 1mcg/m^3) while the hand held left sitting next to it continues to move around especially at the tenth measurement 6.7-9.8 for instance because air is not static.
I’m at a point where I don’t think it can be trusted and I’m feeling like I wasted $138USD. I thought I’d want the data but the night mode isn’t “off” and thus it’s just as bad as the competitors. I wish I’d spent the extra $60 and bought a purple air indoor unit or saved $60 and bought a temtop m10.
I love the product...it's accurate and informative. I bought it when wildfires created days of smoke in my area. It validated that my air conditioning filter was taking most of the pollutants out of the indoor air. A bit challenging to pair, but finally figured it out...
Setup was pretty easy, just make sure you're connected to a 2.4ghz wifi network.
The device itself looks decent, and fits in well with most home furnishings. Honestly, you probably won't notice it too much until you look for it, which is good - it's non-obtrusive.
I live in a pretty clean air city, and the sensor seems to indicate this quite accurately. Would be curious how it works in somewhere like Beijing or Shanghai. It's a well-designed device that does exactly what it advertises.
Thanks for the review and we are happy you love the product!
Value for money product !
Given the PM2.5 situation in Thailand, this is a godsend.
I took it around with me one day and discovered exactly how different the quality of air is indoor and outdoor.
The reading inside my own house with open windows was 35.
Walking beside the road, it skyrocketed to 80.
In my air-conditioned office, the egg indicated 8 (see photo).
Now I now where I should wear a face mask and where I can just relax and take a deep breath of clean air.
