About this item

Product details

The GermGuardian Home Air Purifier Tower is ideal for pet lovers, remote workers, new parents refreshing a nursery, cooking enthusiasts, and anyone who cares about their home's air quality. Perfect for your living room, kitchen, or nursery, this pet air purifier circulates air every 12.5 minutes in a 153 sq. ft. room and is ideal for large spaces. Equipped with a True HEPA 3-layer system filter, UV-C light, and activated carbon filter, this indoor air purifier captures 99.97% of dust, pollen, and pet dander as small as 0.1 microns.* Most air purifiers for bedroom spaces stop at capturing particles; this one adds an optional UV-C light to help reduce allergens.** Pick from three speeds, with sound as low as 40dB on the lowest speed, making it perfect for nurseries. Refresh any stuffy basement, dusty bedroom, and busy office with this plug-in air purifier. Upkeep is simple: vacuum the pre-filter monthly to help extend filter life, swap HEPA filter every six months, carbon filter every three months, and the UV-C bulb every 10 to 12 months. For the best results, use only Genuine GermGuardian replacement filters: HEPA Filter B (FLT4825, FLT4825SM, FLT4825VO, FLT4850PT, FLT420B), UV-C Bulb LB4000, and carbon filter FLT22CB4. Zero Ozone Verified, CARB- and ETL-certified, and engineered in the USA. *Initial efficiency value. As small as 0.1 microns from the air passing through the filter media. **Testing was performed with non-living organisms.
  • True HEPA 3-Layer Protection: This tower purifier works around the clock. The True HEPA filter captures 99.97% of smoke, dust, pollen, and pet hair as small as 0.1 microns.* Ideal as a large room air purifier, it cleans 153 sq. ft. in 12.5 minutes or 743 sq. ft. in one hour.
  • UV-C Light, No Sprays Needed: Most home air purifiers stop at capturing particles. GermGuardian goes further. As air passes through the filter, optional UV-C light helps reduce airborne germs, bacteria, and mold spores.** It works without sprays or added fragrances and is independently verified Zero Ozone.
  • Advanced Air Filtration System: This activated carbon air purifier captures VOCs and larger particles, helping to extend HEPA air filter life while reducing odors from pets, cooking, and wildfire smoke.
  • Quiet When You Need It: Three quiet speeds, from gentle 40dB white noise to powerful airflow, make this bedroom air purifier perfect for nurseries. Turn it up after spring cleaning or to air out basements.
  • Easy Care: Swap the HEPA filter every six months, the carbon filter every three months, and the UV-C bulb every 10 months. Fits HEPA Filter B (FLT4825, FLT4825SM, FLT4825VO, FLT4850PT, FLT420B), UV-C Bulb LB4000, and carbon filter FLT22CB4.

Air Purifier

I am happy with my Air Purifier purchase so far, as I received them today, so I haven't had them long enough to thoroughly test them out. i love that they are very quiet and easy to use.
