Note: When the indoor PM2.5 value is greater than 150, it is displayed in red, indicating that the air quality is poor at this time; when the PM2.5 is 75-150, the indicator light is orange, indicating that the air quality is general; when less than 75, it is green, indicating that the air quality is excellent.
Both sides of the Xiaomi Mijia air purifier 3 fuselage and front of the fuselage are designed with dense small hole air inlets to ensure that the surrounding air enters the purifier interior with a large flow rate from three sides to filter.
The air outlet is designed as a large area of grid installation, which is conducive to the rapid and uniform transportation of air flow. Simply put, the purifier is the process of pumping air into the interior through the following three air ducts, filtering the filter element and then flowing out from above to form a 360-degree air eddy current to gradually purify the indoor air. Mijia air purifier 3 can transport up to 6660L of clean air per minute, the purification efficiency is still relatively fast.

Then the quality of the filter element will directly affect the air purification effect, Mijia air purifier 3 is still an integrated design, the advantage is that the cost is relatively cheap, the disadvantage is that once the end of the service life must be replaced as a whole.
Through the decibel tester at a distance of about 50cm from the purifier, the working noise of the purifier in sleep, 1, 2 and 3 wind speed modes were measured, which were 38.2dB, 39.2dB, 53.5dB and 60.3dB, respectively.
