A breakthrough combination of advanced filter media and an encapsulated ion particle charging chamber makes it possible for the Blueair air purification system to achieve better results than either mechanical or electrostatic technology alone. This filter contains millions of non-toxic ultra- thin polypropylene fibers that trap tiny particles as they pass through the pleats. 

Why polypropylene? Because it is one of the least harmful plastics for human health and the environment,  does not release any gas elements, and does not release any irritating microscopic fibers into the air.

Also, this type of fiber eliminates bacteria, viruses and mold naturally, without chemical additives also captures more dirt than competitive systems. The used filter media also decomposes into harmless carbon dioxide and water, a very environmentally friendly feature.

Particles that a normal HEPA filter alone might miss are captured with an electrostatic charge. HEPASilent™ technology moves particles through an enclosed ion chamber, which attaches a charge to the particle itself. Charged particles cling more easily to the filter media, resulting in higher filter efficiency overall. Because most electrostatic air cleaners charge the filter media itself, the charge dissipates over time and renders the filter less efficient. By constantly charging incoming particles, instead of the filter, HEPASilent™ technology keeps on working effectively and reliably.  Very important for those with allergies.

*Standard HEPA filters measure efficiency at 0.3 microns. A typical HEPA filter removes 99.97% of particles of the 0.3 micron size. The BLUEAIR HEPASilent technology removes 99.97% of particles at 0.1 micron on it's lowest speed

Outstanding filter technology from BLUEAIR--just one more reason to feel safe about the air you breathe.
