What is the best cheap air purifier?

Best cheap air purifier for most people: Levoit Core 300S. It’s a strong budget pick because it has a true HEPA-style filtration setup, smart controls, an auto mode, and a compact size that works well in bedrooms, offices, and small-to-medium rooms.

If you want to spend less upfront, choose the Levoit Core 300. If you want the lowest ongoing hassle for a bedroom, consider the Blueair Blue Pure 511. If you need a cheap purifier for a larger room, look at the Winix 5500-2 when it’s on sale.

Before buying any cheap purifier, check three things: replacement filter price, room size rating, and noise level on the setting you’ll actually use.
