Blueair 450 E Air Filter Systems : How It Purifies Air

With the help of its purification technology, the Blueair 450 E is able to remove particles as small as 0.1 microns with 99.97% efficiency.

This level of purification is achieved because the filter media is made of millions of tiny fibers of different sizes, which are layered and then folded in a pleated arrangement to allow for an increased filtration surface area.

The physical make of a particle filter along with the device’s airflow is what allows for efficient mechanical filtration of larger air contaminants.

Each Blueair air purifier, including the 450 E, is fitted with a built-in ionizer that releases negatively charged ions.

These ions cling to the smaller incoming particles and are then attracted to the positively charged filter media.

The combination of these two types of filtration techniques allows Blueair to use thinner filters, which means that less energy is consumed, and less noise is generated to push the air through the filters and out into the room.
