Formaldehyde S1 filter for the Mi Air Purifier

This anti-formaldehyde filter has a cylindrical aerodynamic construction which provides 360 degree filtration, it is an efficient triple filter made with a base filter mesh layer, high efficiency E11 filter and an activated carbon filter. The Mi Air Purifiers are so effective thanks to their high quality and ease of use and replacement. This filter is compatible with Xiaomi Air Purifier 2/2S/2H/3H/Pro.

• PM2.5 particles
• Compatible with Xiaomi Mi Air Purifier 2 / 2S / 2H / 3H / Pro

Efficient HEPA filter

HEPA (High-efficiency Particulate Arrestance ) is often used in hospitals and laboratories to filter micron size particles. The Mi air purifier uses an ultra-thick Toray PP and PET HEPA filter to trap PM2.5, PM0.3, pollen and other inhaled particles, allowing only clean air to flow. The filter measures 7.7 m when fully developed and effectively filters out 99% of PM0.3 and 99.99% of PM2.5 particles.

Purification with activated carbon

Active carbon absorbs harmful gases that HEPA is unable to filter. Coconut activated carbon in Mi Air Purifier filters is among the most effective of its kind. It is combined with an anti-formaldehyde formula that effectively absorbs harmful chemicals such as formaldehyde, benzene and ammonia, as well as odours and smoke.

Monitor it in real-time

All filters lose their effectiveness over time and must be replaced eventually. Filters that are not replaced on time may not be able to block out harmful substances or may cause secondary contamination. Cleaning old filters with water or vacuum cleaner does not guarantee that the filter will regain its effectiveness. We recommend replacing the filters every six months or less, depending on the use. Use the Mi Home application to monitor the life of your filters and receive reminders to replace them.
