True HEPA filter
Triple-layer filtration

To get the best purification results, we've upgraded to highly effective HEPA filters that remove 99.97% of particulate matter of size 0.3μm or larger, creating a room full of clean, pure air so that you can breathe easy.

PET Primary filter
360° cylindrical filtration

Made with PET (polyethylene terephthalate), the outer layer is 3 to 5 times tougher than comparable models. It has high flexural strength and is resistant to folding, grease, fats, acids, alkalis and most solvents. The cylindrical shape provides 360° filtration of dust, hair and other larger floating particles.

Filter replacement is a breeze
Change filters in 10 seconds

Typical air purifiers require you to change filters layer by layer. Mi Air Purifier 2H simplifies this by integrating all three layers. Simply pull out, and push in. It's that easy.

  • Pull out old filter
  • Pop in new filter

Alerts you to change filters
Monitor filter usage in real time

All filters lose effectiveness over time and must be replaced promptly. Filters not replaced on time may not block harmful substances or may cause secondary contamination. Contrary to what others may advertise, cleaning old filters with water or a vacuum cleaner does not guarantee that the filter will regain its effectiveness.

We recommend you change filters every six months or less, depending on usage. Use the Mi Home app to monitor filter lifespan and receive notification reminders when your filter needs replacing.

  • Smart filter alerts
  • Replace every 4-6 months
