Breathe easier and purify your space with the GermGuardian AC4825 22" Tower Air Purifier. Designed for rooms up to 743 sq. ft., it’s perfect for bedrooms, living rooms, and open spaces. Its True HEPA 3-layer filtration captures 99.97% of dust, pollen, smoke, and pet dander as small as 0.1 microns*, helping reduce allergy and asthma triggers. The optional UV-C sanitizer adds extra protection by targeting airborne germs, bacteria, mold spores, and viruses**, while being independently verified Zero Ozone Certified. With three speed settings and whisper-quiet operation, it provides gentle white noise at night. An activated carbon layer traps larger particles and neutralizes odors from pets, cooking, and smoke. For optimal performance, use genuine GermGuardian replacements: HEPA Filter B (FLT4825 series), UV-C Bulb LB4000, and carbon filter FLT22CB4. Designed and tested in the USA, GermGuardian has delivered cleaner air you can trust since 2005.
