Best Overall Basement Air Purifier
Hathaspace Smart Air Purifier
This five-in-one air purifier filtration system removes particles as small as 0.3 microns while also eliminating 99% of smoke. Equipped with a four-stage HEPA filter, the Hathaspace does a number on dust and allergens, pet hair and dander, smoke, VOCs, viruses, bacteria and musty odors—effectively cleaning up to 700 square feet of air per hour. We also love how the freestanding unit’s slim profile means you can lean it up against a wall or on a counter so it’s out from underfoot.
