Snoop's Take

The GermGuardian 4-In-1 HEPA Air Purifier is a no-nonsense air cleaning machine designed to capture 99.97% of airborne particles and odors in rooms up to 743 sq. ft. It employs a True HEPA filter, activated carbon, and UV-C technology to combat allergens, smoke, and pollutants. Consumer chatter paints a polarized picture: on one hand, users rave about its efficacy—one even noted, “I've tried a couple of different air purifiers, but the one I use now is a GermGuardian, and it works great”—while others decry its gimmicky UV light and the maddening need to replace non-washable filters. The debates are as lively as they are pointed, with some users hailing its long-term reliability and others warning that cleaning the filter is a fool’s errand. Bottom line, while the device wins hands down on basic filtration and allergen reduction, its quirks and maintenance demands may not suit everyone; if you can live with its shortcomings, it's a solid choice in its class.

I've tried a couple of different air purifiers, but the one I use now is a GermGuardian, and it works great.

Positive Feedback

You damage the filter media by cleaning them, so it wont filter as well and smaller particles will make their way through it.
