• GENUINE HEPA PURE FILTRATION – Experience the power of authentic HEPA PURE air filtration. Genuine GermGuardian high efficiency HEPA air filters capture 99.97% of dust, allergens, and wildfire smoke particles down to 0.1 microns from the air.

  • WHY HEPA PURE - HEPA PURE stands out with its multi-layer filtration technology. Backed by scientific testing, we combine extensive research and superior materials to outperform the competition. Beware of knockoffs that compromise on quality
  • PURE PARTS, PURER AIR - Genuine GermGuardian replacement filters guarantee certified fit and maximum filtration. Off-brand filters frequently fail HEPA testing standards, fit incorrectly, reduce efficacy, and may cause damage to your GermGuardian air purifier. Your purifier is only as powerful and effective as the filter you put inside.
  • REDUCES ODORS - The activated carbon pre-filter traps dust, pet hair, and other large particles, while extending the life of the HEPA filter. Treated carbon absorbs volatile organic compounds from the air and reduces odors from smoking, cooking and pets. The FLT21CB4 {ASIN: B08V98KPNQ} carbon pre-filters can be replaced every 2-3 months to help reduce common household odors and extend filter life.
