I have this in my bedroom. I'm always amazed at what this Blue Pure 211i Max collects that I don't see and think how happy I am that I didn't breathe that crap! I have ILD and grateful for this air purifier.
BlueEU Staging6 days agoThank you for sharing your feedback with us. That is incredible to hear, and your reaction is so relatable! It is always shocking to open up an air purifier filter and see the thick layer of dust, dander, and microscopic fibers that would have otherwise ended up in your lungs. The Blue Pure 211i Max is a powerhouse for a bedroom because its HEPASilent™ system traps 99.97% of airborne particles down to 0.1 microns (including invisible pollen, mold spores, fine dust, and pet dander) while cycling the air in a large room multiple times an hour. Wishing you many more restful, clean-air nights ahead!

BlueEU Staging1 week agoThank you for sharing your valuable feedback with us. That is so great to hear! Breathing clean air makes a huge difference in daily energy, sleep, and overall well-being. Blueair's HEPASilent™ technology is a standout in the industry, it uses electrostatic charging alongside mechanical filtration to trap 99.97% of fine particles down to 0.1 microns while keeping noise levels super low. Enjoy that clean air!

All you need to do is look at the photo - the Blueair 300i+ Max and its filter system deliver on what they promise! I have an indoor cat and I keep the purifier a few feet away from his litter box. My one regret is not buying this system years ago.
