Mi Air Purifier 2 Filter

Traps from all sides

How well a filter performs depends on its
purification ability and aerodynamic design.
Supplied by top-quality suppliers, the triple layers
consist of a primary filter, high-density EPA filter
and activated carbon filter. Easy to use and
replace, its balance of power and quality is
what makes Mi Air Purifier 2 so effective.

Clean air for the whole family.

PET primary filter

360° filtration of large particles

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.

Ultra-dense EPA filter

Finely folded to trap respirable particles

Mi Air Purifier 2 uses an ultra-dense Toray EPA filter to trap PM2.5, PM0.3, pollen
and other respirable particles, allowing only clean air to pass through.

Activated carbon filter

Removes formaldehyde, odours and more

Activated carbon adsorbs harmful gases across a large surface area. It is combined with
an anti-formaldehyde formula that effectively adsorbs harmful chemicals such as
formaldehyde, benzene and ammonia, as well as odours and smoke.

Filter replacement is a breeze

Change filters in 10 seconds

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

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

Replace every 4-6 months
