Coming clean

How well a filter performs depends on its purification ability and aerodynamic design. Supplied by the top 3 US air purifier manufacturers, the filter combines an aerodynamic 360 cylindrical design with a powerful triple-filter consisting of primary, HEPA and activated carbon layers. Easy to use and replace, its balance of power and quality is what makes Mi Air Purifier so effective.

Ultra-dense H11-grade HEPA filter

Filters up to 99.3% of PM0.3

HEPA (High-efficiency Particulate Arrestance) is frequently used in hospitals and labs to filter out micron-sized particles. Mi Air Purifier uses an ultra-dense Toray PP and PET HEPA filter to trap PM2.5, PM0.3, pollen and other inhalable particles, allowing only clean air to pass through. It measures 7.7m when fully extended and effectively filters out 99% of PM0.3 particles and 99.99% of PM2.5 particles.

Quality coconut activated carbon

Filter sourced from Southeast Asia

Activated carbon absorbs harmful gases that HEPA is unable to filter. Mi Air Purifier's coconut activated carbon 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 odors and smoke. It offers a total specific surface area of 57,000m, or 8 soccer fields.

Real-time usage monitoring

All filters lose effectiveness over time and must be replaced promptly. Filters not replaced on time may not be able to 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 your usage. Use the Mi Home app to monitor filter lifespan and receive notification reminders when your filter needs replacing.

Special activated carbon

Filter to tackle formaldehyde

Found in many paints and in furniture made from plywood, formaldehyde is harmful to the human body and dissipates slowly. We built the special activated carbon filter specifically for the purpose of removing formaldehyde and other harmful substances.
