Best purifier & long filter life

"I expected my filter to go in 6 months but it lasted 9 plus. The air is so fresh and clean. I love it"

— Heather (5/5)

"Expensive but excellent product"

— Patrick (5/5)

What a gimmick.

"9-12 months my ass. I’ve had this air purifier since January. Running on the lowest speed 24/7. It’s May and this thing is shot. At this rate it may as well be a car payment to circulate some air in an average sized apartment. Duped. I’d consider something at 1/5 the cost to accomplish the exact same results."

— William (1/5)

Great air filter

"I’ve tried several air purifiers and I love all the features of the i35. The odor filter does work the best and I have noticed a big difference in the air quality and less dust since I’ve been using this air purifiers."

— Brain (5/5)

Q&A

does fresh filters capture pet dander as well ? does the odor filter do everything the fresh filter does and then some ?
Pet dander is a particulate so the Fresh filter would caputre it, but not neutralize the odor of the dander. Yes, the odor filter covers all the concerns of the Fresh Filter plus odor protection
