Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

I am a happy camper and think it is a good value. The display is for the most part excellent. It is usb powered and has a lighted display! I like that it uses a gd32f103 micro. Interface. Above aqi=200, the us epa and china formulas are the same.

The sensor is based on a plantower pms5003 sensor. It seems to be accurate as measured against government equipment and follows air quality conditions as you'd expect (such as turning on or off an air purifier) the user interface and readings are simp... Read More

Cons

The device is very inaccurate, and may be used only for crude measurements of air quality. Shows almost pristine air quality in an enclosed room with no fewer than three stinking sputtering 3d printers. The particle counts it's giving are impossible o... Read More

Price

I am a happy camper and think it is a good value.

Pretty impressive little box for not much money.

To me it's worth a few extra $$$ for an out of the box mostly working example!

At $50 a pop, they could have at least fixed that by now.

Competitiveness

I've tested this with other more expensive units out there and it's definitely accurate.

We have 6 "purpleair" sites near us and the results of this device compare favorably to the raw data from these sites.

Above aqi=200, the us epa and china formulas are the same.

If this unit shows an aqi between 76 and 200, that is equivalent to us epa aqi from 150-200.
