Large particles such as dust and pollen are captured in the first layer
consisting of larger fibers. In this stage particles are electrically charged and trapped by direct contact with the filter fibers.
Second Layer: This layer consists
of a finer fibers that collect smaller particles such as
bacteria and allergens. This layer of the filter intercepts the smaller particles that escaped the first
Third Layer: In this layer, much smaller
particles like viruses, mold, pet dander and minute particles are
filtered out. This layer consists of ultra-fine fibers, as small as 0.5
micron. Minute Particles enter this layer with an imparted negative charge and
easily adhere stick to the fibers, thus capturing particles as small as
0.1 micron at 99.97% efficiency.
The new Dual Protection Replacement Filter provides:
Uncompromised Particle Removal:
The new Blueair DPF (Dual Protection Filter) efficiently removes micro-plastics, dust, mold, pet dander, viruses, bacteria, pollen and more. 99.97% of particles down to 0.1 microns. To put that in perspective 0.1 microns is 1/500th the diameter of a human hair. That's really tiny. And this filter does this without reducing the Clean Air Delivery Rate.
Much Faster Gas and Odor Reduction:
The Blueair Dual Protection Filter utilizes finely granulated activated activated coconut shell carbon. This renewable resource carbon efficiently removes gases and odors like traffic exhaust, smoke, cooking odors smog, airborne chemicals pet odors and more. Efficiently reducing these airborne contaminants up to 4 times faster than other carbon filters.
No Chemicals Added:
With the natural capabilities of pure activated coconut shell carbon the new DPF filter needs no additional chemical additives. Just sustainably sourced high quality, high porosity coconut carbon. The new Blueair Dual Protection Filter combines high efficiency particle removal with the best gas and odor reduction filtration that Blueair has ever produced.
