Blueair Classic 280i Air Filter Systems : How It Purifies Air

The purification process begins with the smart integrated filters that closely monitor the air quality to detect even the slightest changes in the air quality.

These readings are then used by the air purifier to manipulate the fan speed to optimal levels to draw the air into the purifier with the help of its ultra-silent fan.

Upon entering the air purifier, the particles in the air become electrostatically charged so that they are forcefully attracted to the filter material.

The combination of HEPA particle filter and the SmokeStop™ filter successfully captures all kinds of impurities.

A combination of this ionization technique and mechanical filtration allows the highest air velocity and giving you maximum clean air with minimal noise and power consumption.

The fresh air is pushed into every corner of the room.

The filters of Blueair air purifiers are specifically designed to suit each device’s airflow and unit size to ensure maximum air purification efficiency.
