The GermGuardian Hi-Performance is a tower air purifier for large rooms up to 335 sq ft. It combines a true HEPA filter, a charcoal odor filter, an optional UV-C light and an optional ionizer, with three fan speeds. It suits bedrooms, living rooms and pet or allergy households that want odor and germ control as well as particle filtration. Against rivals it adds UV-C and an ionizer at a modest build quality, and owners say it cleans well but is loud on high and needs filter replacements.

Owners say it noticeably reduces dust, pet dander and odors in large rooms and runs quietly on low. Many find high speed too loud for a bedroom and dislike the cost of replacement filters.
This GermGuardian air purifier is a four-in-one unit that combines a HEPA filter, a charcoal filter, UV-C light and an optional ionizer. It is designed for large rooms up to 335 sq. ft.
The HEPA filter captures 99.97% of dust and allergens as small as 0.3 microns, including household dust, pet dander, mold spores and plant pollen. The charcoal filter reduces common odors from pets, smoking and cooking. The optional UV-C light works with titanium dioxide to reduce airborne bacteria, viruses, germs and mold spores.
The purifier has three fan speeds, and the low speed runs ultraquiet. An optional ionizer can be turned on to boost allergen control.
