GermGuardian Full Room Air Purifier

Last updated: January 10, 2024

This air purifier does solid work without a lot of bells and whistles, at least on the outside. It's easy to use and replace the filters, but the extra charcoal filter (and optional UV-C light) make it equally good at trapping odors and allergens. And with a low power consumption, it's ideal for heavy use in medium-sized rooms.
