Blueair Classic 680i Air Filter Systems: How It Purifies Air

Blueair’s unique HEPASilent™ technology combines two different filtration technologies.

While typical air purifiers rely on mechanical filtration, the Blueair Classic 680i is a potent combination of electrostatic and mechanical filtration.

The high airflow and electrostatic charging kill 99% of viruses and bacteria. The charged particles stick like magnets to the filter, trapping even the smallest particles.

The fan draws in the pollutants into the air purifier, where they become electrostatically charged.

The air then passes through the Blueair filter, making use of activated carbon and HEPA made with naturally antibacterial materials.

Activated carbon effectively adsorbs chemicals, smoke, and odors.

The three-step filtration ensures that the Blueair filters can be designed to be less dense, allowing higher airflow through the filters.

Therefore, the Blueair Classic 680i air purifier can produce more 100% clean air with lower fan speed.

This clean air is then dissipated throughout the room evenly !
