FreAire KN-6391RGB HEPA Air Purifier with RGB Lights: 3-level high-efficiency filtration system
Here's the kicker: with a dual-channel air inlet and 360-degree air outlet, this little powerhouse can cycle the air in a 215 ft² / 20 m² room five times an hour. That's like giving your room a breath of fresh air, literally. And when it's time to hit the hay, the sleep mode whispers at a barely-there 22 db—so quiet, you'll forget it's on. Plus, for those who love a good scent, the aroma pad lets you infuse the air with your favorite essential oil. Because why settle for clean air when it can also smell like a spa?
