New upgrades
360° complete and effective deep-level purification

a.Integrates a primary filter, a 99.97% efficient HEPA filter and high-quality activated carbon layer all into one.
Not only does the filter effectively remove PM2.5, but it also filters out formaldehyde that off-gases from
household furniture, allergens such as pollen, as well as a range of everyday odors.

Primary filter

99.97% efficient HEPA filter

High-quality activated carbon

Primary filter
Fully intercepts large particles

The filter delivers high-efficiency filtration of dust, pet dander, fine particles as well as other large
particles and is resistant to creases, oil, acids, alkalis and more to ensure a long service life.

Dust

Fine particles

Pet dander

Floccules

Powerful high-precision filter

Uses a 99.97% efficient filter material that fully intercepts inhalable particles, protecting your family'shealth.

0.3 μm PM

Allergens such as pollen

Evenly folded peaks Increased air flow efficiency

The filter is made from folded HEPA materials and featuring uniform folds thanks to high-pressure folding provided by precision machinery, delivering improved airflow and reduced air resistance.

High-pressure folding reduces air resistance—Air passes through quickly

Precise monitoring of distance between
folds—Air passes through evenly

Laser positioning and gluing

High-quality activated carbon formula Effectively absorbs formaldehyde and odors

Ample amounts of powerful catalytic activated carbon have been packed into each layer of the filter structure to increase contact time between the air and the activated carbon, and the efficient contact area effectively removes harmful gases such as formaldehyde as well as everyday odors.

Formaldehyde

Odor

TVOC

Large size, Huge dust capacity The filter can be used for up to 14 months

The large surface area of the H13 filter paper and ample amounts of high-quality activated carbon offer high-efficiency purification and long-term cleaning.

Smart status alerts All-in-one filter for easy replacement

An OLED screen automatically displays the filter status once the purifier is switched on. Use
the Mi Home app to check at a glance filter usage as a percentage while the all-in-one filter
design makes replacement both quick and easy.

*Changing the filter every 10–14 months is recommended: In accordance with GB/T 18801-2015G.2.1, the Mi Air Purifier Pro H Filter can filter a CCM of 47,000 mg of PM indoors with a surface area of 72 m2, a room height of 2.4 m and an average outdoor fine PM concentration of 150ug/m3 when using the purifier on automatic mode for an average of 12 hours a day. Values for air change rate, penetration coefficient, PM sedimentation concentration, indoor fine PM target concentration, etc. are based on GB/T18801-2015 G.2.2.1. The recommended filter replacement period of 10–14 months was calculated with reference to formula (G.4). Service life is an estimate and is provided as a reference for replacement cycles only.
 *Up to 99.98% filtration efficiency for 80–90 nm particles: The material used for the filter of this product was able to filter up to 99.98% of 80-90 nm particles when tested at an air flow rate of 0.0533 m/s. The counting efficiency of other PM particles of different diameters was also measured. Data obtained from the China Household Electrical Appliance Research Institute (CHEARI). Test No.: WCv-20-40030.
*The filter medium can remove >99.97% of particles as small as 0.3 microns in charged condition, according to GB/T 6165-2008 test method of the performance of high efficiency particulate air(HEPA) filter-—Efficiency and resistance.
*99.97% filtration efficiency of 0.3 pm for PM: According to tests carried out by the National Quality Supervision and Inspection Center for Air Conditioning Equipment, the filter material used in this product has a filtration efficiency of 99.97% for PM ≥0.3 pm. Report No.: NCSA-2019H-0002.
*Expanded filter paper surface area of 35,000 cm: Data obtained from Smart Mi Lab, and may vary slightly due to differences between individual products. *CCM of formaldehyde >F4: According to "Air Filters" (GB/T 18801-2015), a Cumulative Clean Mass (CCM) of formaldehyde ≥1500 mg meets Grade F4 levels. The CCM of formaldehyde in the Mi Air Purifier Pro reached 2000–2500 mg which exceeds Grade F4 levels. Data supplied by China Household Electric Appliance Research Institute (CHEARI). Report No.: WCk-19-50352.
*CCM of PM 3 times greater than Grade P4: According to "Air Filters"(GB/T 18801-2015), a Cumulative Clean Mass (CCM) of PM ≥12,000 mg meets Grade P4 levels. The CCM of PM in the Mi Air Purifier Pro H reached 47,453 mg which is 3 times greater than Grade P4 levels. Data obtained from China Household Electric Appliance Research Institute (CHEARI). Report No.: WCk-19-50352.
