Our take on the GermGuardian AC4700 HEPA PURE 15" Tower Air Purifier

The GermGuardian AC4700 is a 15-inch tower air purifier with three filtration stages: a pre-filter, a charcoal filter for odors, and a HEPA filter rated to capture 99.97% of particles down to 0.1 microns. A UV-C light adds bacteria and mold-spore reduction, and the unit has three speeds, a UV-C on/off control and a filter change indicator. It is rated for rooms up to 728 sq. ft., but its CADR figures (106 dust, 106 pollen, 97 smoke) are modest for that size, so it cleans a medium room well rather than a large open space. It suits allergy sufferers and pet owners who want odor control and a slim footprint; against larger rivals it trades raw cleaning power for a light 7.55 lb body and a low quiet speed.

Questions and answers

How often do I replace the filter?
GermGuardian generally advises replacing the HEPA filter about every 6 to 8 months, and the charcoal filter more often, depending on use. The filter change indicator tells you when it is due.
Does it really cover 728 sq. ft.?
The 728 sq. ft. figure is a maximum. Its CADR of about 100 means it cleans a medium room well but will struggle in a large open space, so size down for better results.
What filters does it take?
It uses Guardian filter M (FLT4700) for the HEPA stage and the FLT47CB4 carbon filter pack. Using the correct parts keeps the filtration and warranty intact.
Can I turn off the UV-C light?
Yes. There is a dedicated UV-C control, so you can run filtration alone if you prefer.
Is it good for pet odors?
The charcoal stage is designed to capture odors from pets, smoke and cooking. Owners report it helps with pet smell in a closed bedroom, though it is not a whole-home solution.
How loud is it on high?
The low speed is the quiet setting owners praise. High moves more air but is noticeably audible, so most people use it on low or medium overnight.
