Our take on the GermGuardian AC4625 HEPA PURE 22" Tower Air Purifier

The GermGuardian AC4625 is a tower air purifier with a 360° True HEPA filter that captures 99.97% of particles down to 0.1 microns, plus an optional UV-C light and activated carbon layer for odors. It cleans a 155 sq. ft. room in 12.5 minutes and up to 750 sq. ft. per hour, with three speeds including an ultra-quiet low setting. It suits bedrooms, living rooms, and offices where allergy and asthma triggers are a concern. Compared with rivals, it offers UV-C and a 360° intake at a mid-range price, but replacement filters and bulbs add to long-term cost and the UV-C lamp has a shorter life than the HEPA filter.
