If you want to check other air purifiers from Xiaomi, check out our previous review about the Mijia Air Purifier Pro 4 Pro.

First Impressions

It moves so much more air and can clean bigger rooms without using more energy than the previous models. Pro H is slightly bigger than the other models with its 31x31x73.8cm dimension. It is just huge, and what many do not realize is Xiaomi Air Purifiers are actually inverted air purifiers.

These are the same motors found inside premium air purifiers made by Daikin, LG, Samsung, or Panasonic. The only difference is that they market them as inverter air purifiers, but Xiaomi just does not do the same thing.


If you want to use the Mijia Air Purifier Pro H manually you can do it through the app, but before that, there are Sleep, Low Speed, Medium Speed, High Speed, and Automatic modes available. With the OLED touch screen display, you can track the temperature and humidity, and also you can turn on and off the Mijia Air Purifier Pro H. There is also a LED indicator on the display which you can see the Air Quality. Colors are displayed according to the PM2.5 value. These are the:

  • Green: 0-75µg/m3
  • Orange: 76-150µg/m3
  • Red: 150µg/m3


Open the filter compartment by pressing the buckle, and make sure the filter is installed correctly. Remove the power cord, and close the filter compartment. Then, connect the power cord to the connector of the Mijia Air Purifier Pro H, and then plug it into an outlet, and it is almost ready to use.


Mijia Air Purifier 4 Pro H has a completely new filtration design that is much larger than the previous cylindrical filters. It is a Hepa H13 Grade filter, which means it can trap up to 99.97% of particulates as small as 0.3-micron. Mijia Air Purifier 4 Pro H also boasts upgraded activated carbon granules that Xiaomi said are more effective than the older version of the filter found in the last-gen Pro. It also has a lifespan of up to 14 months.

Mi Home App

Like other Xiaomi Smart Products, Mijia Air Purifier 4 Pro H does have Wi-Fi capabilities as well as Mi Home App control. You can download the Mi Home App on Google Play Store, or Apple Store. You can set some automation through the app to ensure that it matches your needs and your lifestyle if you do not trust the laser sensor much.
