The GermGuardian AC4900 is a 22-inch tower air purifier with a True HEPA Pure filter, an activated carbon pre-filter for odors, and an optional UV-C light. It moves a 150 sq. ft. room's air every 12.5 minutes and cleans up to 728 sq. ft. per hour, with three fan speeds and a low-speed quiet mode for bedrooms. It suits people with allergies, pets or smoky rooms who want odor and particle control in one tower. Against rivals, it adds UV-C and carbon odor control at a lower build tier, and it needs genuine GermGuardian filters to keep its certified performance.

Owners generally find the AC4900 effective at cutting dust, pollen and pet odor, and quiet enough for bedrooms on low. Complaints center on filter and bulb replacement costs and on performance in larger rooms.
The GermGuardian AC4900 is a 22-inch tower air purifier for medium-sized rooms. Its True HEPA Pure filter captures 99.97% of smoke, dust, pollen, and pet dander as small as 0.1 microns, which helps reduce allergy and asthma triggers. This is an initial efficiency value, measured on air passing through the filter media.
An activated carbon filter targets common household odors from pets, smoke, and cooking. An optional UV-C light works to reduce airborne allergens, bacteria, germs, mold spores, and VOCs. The UV-C claims were tested with Staphylococcus Albus, Escherichia Coli, Aspergillus Niger, and Phi-X174.
The purifier has 3 fan speeds. The lowest speed is a quiet mode for sleeping. A UV-C control and a filter change indicator are built in.
