    Customized Filter


    Tailor the MinusA2 air purifier to fit your personal needs


    Germ Defense Filter

    Effectively traps and reduces airborne bacteria, mold spores and particles that carry viruses

    Pet Allergy Filter

    Traps and reduces pet dander and pet allergens

    Toxin Absorber Filter

    Traps and reduces volatile organic compounds (VOCs) and other chemicals

    Odor Remover Filter

    Advanced HEPA Filtration

    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.

    BioGS HEPA Filter vs. typical True HEPA Filter

    Typical True HEPA filter:


    • Traps allergen and particles 0.3 microns in size at 99.97% efficiency and over 99% efficiency for particles less than 0.1 microns


    BioGS HEPA Filter:


    • Traps allergen and particles 0.3 microns in size at 99.97% efficiency and over 99% efficiency for particles less than 0.1 microns**
    • Reduces buildup of common allergens including dust mites, mold, pollen and pet dander* trapped on the filter
    • Reduces the growth of bacteria and viruses on the filter***
    • Prolongs optimal filter efficiency


    *Test samples: mite allergen (Der f2), cedar pollen allergen (Cry j1), 4 types of mixed spores (Aspergillus niger, Penicillium citrinum, Chaetomium globosum, Myrothecium verrucaria), Cat allergen (fel d1)

    ** Test data shows our HEPA filter (brand new or like-new) can trap particles 0.3 microns in size at 99.97% efficiency. Research data shows True HEPA filters can trap particles less than 0.1 microns in size at higher than 99% efficiency.

    ***Test samples: type A influenza virus(H1N1), Escherichia Coli, Staphyllococcus aureus

    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.
