H12 grade true HEPA filter captures 99.97% of airborne particles down to 0.3 Micrometre — removes fine dust, pollen, mold spores and many airborne allergens for cleaner breathing air. Fine preliminary filter traps larger particles such as dust, hairs, pet fur and lint, protecting the HEPA media and prolonging overall filter life. efficiency activated carbon filter absorbs household odors from pets, cooking, smoking, wildfire smoke and harmful VOCs, reducing smells and chemical irritants. Multistage construction (preliminary filter + H12 true HEPA + activated carbon) provides layered protection for both particulates and odors while maintaining airflow performance. Made of material for greater durability and reliable daytoday use; designed to deliver consistent filtration performance over its service life. Performancefocused specification: true HEPA H12 standard and 99.97% capture at 0.3 Micrometre ensures measurable removal of fine particles commonly linked to indoor air issues. Use scenarios Home with pets: captures pet hair and fur in the preliminary stage and reduces dander and fine allergens with the H12 HEPA layer, while the activated carbon lowers pet odors. Kitchen and living areas: removes cooking odors and airborne grease particles, and reduces lingering smoke from occasional indoor smoking or nearby wildfire smoke. Allergy relief and indoor air quality: improves breathing comfort for allergy sufferers by removing pollen and dust mites and reducing VOCs from cleaning products and offgassing materials. Compatibility and care Designed as a multistage replacement filter assembly (preliminary filter + H12 true HEPA + activated carbon) for air purifiers that use those filter stages. Check your device specifications for H12/true HEPA and activated carbon filter requirements. For results, follow your air purifier manufacturer's replacement schedule and handling instructions to maintain filtration performance.
