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.

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 H11-grade HEPA filter 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.

Finely folded 161 times

The ultra-dense HEPA filter measures 7.7m when fully extended. Although ideal for air purification, this creates high air resistance.
To get around this, considerable thought has been put into creating the folding process.

Perfectly folded corners

The sharp, precisely machine-folded corners allow air to flow more smoothly, reducing air resistance.

Carefully calibrated intervals

Intervals between each corner are carefully kept at precisely 3.5mm to maintain an even airflow.

Laser-positioned glue injection

Staggered glue injection with laser positioning ensures consistency and precision.

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 57,000m², or 8 soccer fields.

Conventional activated carbon filter

Higher ash content and impurities, smaller specific surface area, less effective than coconut activated carbon of the same weight.

Mi Air Purifier's coconut activated carbon filter

Greater purity and microporosity (5x that of typical activated carbon), greater specific surface area, relatively lightweight.

Absorbs all kinds of odors and harmful substances

Home renovations and other activities may release substances such as formaldehyde, benzene and TVOC, which can cause harm at high densities. Mi Air Purifier's coconut activated carbon filter absorbs hundreds of harmful substances in these situations, keeping your home clean and your family healthy.

Filter replacement is a breeze

The filter design integrates three layers in one for easy replacement. When separated, each filter layer has its own lifespan and can be hard to tell when replacement is needed. Secondary contamination from dust may also occur when replacing filters separately. By integrating all 3 layers, Mi Air Purifier's cylindrical filter addresses these issues and keeps filter costs low.

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.
