Typical HEPA air purifiers trap allergens and contaminants, which accumulate on the filter and interfere with efficiency. The BioGS HEPA filter traps and reduces common allergens* to support optimum filter efficiency and prolong filter life.

Stage 1 - Pre-filter (washable and permanent)
Traps and reduces large sized allergens, dust, and particles.
Stage 2 - Medium Filter
Traps and reduces airborne particles larger than 1 micron in size, such as pollen, mold, and pet dander.
Stage 3 - BioGS HEPA Filter
Traps allergen and particles 0.3 microns in size at 99.97% efficiency, and reduces common allergens to support optimum filter efficiency and prolong filter life.
Stage 4 - Customized Filter
Choose from a variety of customized filters including Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.
Stage 5 - Charcoal-Based Activated Carbon Filter
Made of high-grade granular activated carbon, our AC filter is much more effective than typical AC filters, which are coated with a thin layer of activated carbon. Chemicals and common household odors can be effectively reduced.
Stage 6 - Negative Ion Generator
Produces beneficial negative ions to fortify the air you breathe and freshen your indoor environment.
