The GermGuardian AC4870 is a 22-inch tower air purifier with a 4-in-1 filtration stack: a pre-filter, a charcoal filter for odors, a true HEPA filter rated to capture 99.97% of particles down to 0.1 microns, and a UV-C light. It is rated for rooms up to 743 square feet and gives you five fan speeds, an 8-hour timer and a filter and bulb replacement indicator. It suits allergy sufferers and pet owners who want odor and particle control in a bedroom or living room. Against rivals it is a tall, lightweight tower with no oscillation and no remote, so it moves air in one direction and you set it by hand; the UV-C stage is a feature most competitors at this level leave out.
