The GermGuardian AC4870 is a 4-in-1 digital tower air purifier designed for large rooms up to 743 square feet. Standing 22 inches tall, it combines a true HEPA filter, activated charcoal filter, UV-C light sanitizer, and odor reduction technology in a single unit.

The HEPA filter captures 99.97% of dust and allergens as small as 0.1 microns, including pet dander, pollen, mold spores, and dust mites. The UV-C light helps reduce airborne bacteria, viruses, and mold that pass through the unit. The activated charcoal layer tackles household odors from pets, cooking, and smoke. CADR ratings are 118 for dust, 125 for pollen, and 99 for smoke.

A digital control panel offers 5 fan speeds including an ultra-quiet low setting, a programmable timer up to 8 hours, and UV-C on/off control. Built-in filter and UV-C bulb replacement indicators take the guesswork out of maintenance. The filter requires replacement every 6–8 months. The unit is Energy Star certified, measures 22" H x 10.25" W x 6.75" D, weighs 8.55 lbs, and includes a 72-inch power cord. Backed by a 3-year warranty.
