FreAire KN-6391RGB Air Purifier with RGB Lights: 3-level high-efficiency filtration system
Here’s where it gets even cooler. Thanks to its dual-channel air inlet and 360-degree air outlet, this little powerhouse can flip the air in a 215 ft² / 20 m² room five times an hour. (Yeah, it’s that fast.) Need some shut-eye? Flip on sleep mode, and it’ll whisper at a barely-there 22 db. Plus, there’s a sneaky little feature—toss your favorite essential oil on the aroma pad, and boom, your room smells like a spa. (Or a bakery. No judgment here.)
