Key Features Driving Consumer Adoption

HEPA H13 and H14 Filters: The Gold Standard

High-Efficiency Particulate Air (HEPA) filters remain the cornerstone of effective air purification. True HEPA filters (designated H13 or H14) capture 99.97% of particles as small as 0.3 microns, including pollen, dust mites, mold spores, and pet dander. The latest innovation is HEPA H14, which captures 99.995% of particles, making them hospital-grade technology now available for homes.

Activated Carbon Filters for Chemical Warfare

While HEPA filters excel with particles, activated carbon filters tackle gases and odors. These filters use adsorption (not absorption) to capture volatile organic compounds (VOCs) from paints, cleaning supplies, and furniture off-gassing, as well as cooking odors and smoke. Premium models feature multi-stage carbon filters with enhanced surface areas for maximum chemical capture.

UV-C Light Technology: The Germ Fighter

Ultraviolet C light has gained prominence for its ability to neutralize viruses, bacteria, and mold spores. When combined with HEPA filtration, UV-C creates a powerful one-two punch against biological contaminants.
