Key Features of the GermGuardian AC4825, 3-in-1 Air Cleaning System

Feature #01. True HEPA Filtration

True HEPA is superior in quality when it comes to filtering allergens from the air. True HEPA filters are proven to capture 99.97% of airborne allergens such as household dust, pet dander, mold spores, and plant pollens and particles as small as .3 microns in size. That can make a big difference in air quality.

Feature #02. The Power of UV-C

UV-C light kills bacteria and viruses, including rhinovirus, E.coli, and Streptococcus. UV-C light sanitizes by permanently damaging the DNA of germs, so they die.

Feature #03. Indicator Lights for Filter and UV-C Bulb Replacement

The GermGuardian AC4825 is equipped with indicator lights that automatically blink when it is time to replace the Filter or UV-C bulb. No more trying to remember the last time you replaced your filter. If the reminder lights are blinking when the air purifier is turned on for the first time, just reset the system by holding the UV button for at least 3-5 seconds or until the reminder lights stop flashing. The product is now set and ready to go.

Feature #04 ENERGY STAR Qualified
