Key item features

  • Guarding Your Air: With 3 layers of 360 degree protection, the genuine HEPA Pure air filter captures 99.97% of particles as small as 0.1 micron from all directions. With over 155 pleats and 14 square feet of filter area, our True HEPA air filter traps dust, pollen, and pet dander.
  • Intellisense Air Quality Monitor: Measures the room air quality 60 times per minute using a PM 2.5 sensor detecting tiny particles in the air smaller than the diameter of a strand of human hair. It automatically adjusts the speed when poor air is detected and returns to a lower speed after cleaning the dirty air. Always Monitoring, Always Cleaning - every second of the day.
  • Clean Air in 12.5 Minutes: Circulate and filter the air in a medium 226 sq. ft. room every 12.5 minutes or in a large 1080 sq. ft. room every 60 minutes. Efficacy testing is performed in 30 cubic meter testing chambers to ensure accurate results and performance that is replicable in the real world.
  • Reduces Odors: 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.
  • Traps Allergens: filter captures airborne particles such as dust, pollens, debris and pet dander
  • Quiet Operation: 4 speed options with the lowest setting being utilized as gentle white noise for a quiet, restful night's sleep.
  • Genuine Filters: Replacement filter is GermGuardian HEPA Filter V (FLT151, FLT151SM, FLT151VO). Genuine GermGuardian replacement filters for certified fit and maximum filtration. Off-brand filters often fail HEPA testing standards, fit incorrectly, reduce efficacy, and may cause damage to the air purifier.

Excellent Air Purifier at a Great Price

Great value and performance. The price was much better than other big box stores, and delivery was fast!!! I already own four other GermGuardian products, and this one does not disappoint. I really like that it shows when the air quality isn't good—it's a helpful feature. It's also super quiet when running on auto mode.
