Xiaomi M1R-FLP Mi Air Purifier Anti-formaldehyde Filter
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.

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.

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.
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.
