You’ll pay a premium, but it’s hard to beat the high-quality purification you get from a top-of-the-line Dyson purifier. With its sleek open design, the TP07 combines HEPA and charcoal filters with smart sensing tech that automatically detects airborne contaminants and “air multiplier” tech that draws in pollutants from across the room.

According to the brand, Honeywell is the number one choice among allergists, experts on the effects of contaminated air and the benefits of breathing clean air. With a certified HEPA filter that can trap contaminants down to 0.3 microns in size (a typical size for viruses, smoke, and bacteria), and outfitted with advanced filters to combat your specific air antagonists, the HPA5300B is a clear winner.
