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."

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)

"Expensive but excellent product"

Patrick (5/5)

"if it does it's job, then i won't have to reorder."

Chef (4/5)

Disappointing filter life

"The filter light came on in April for the filters I bought (2nd round) in December. They don't look dirty, so I don't know what to think. I have 2 i35s, and they are in small rooms - a bedroom and an office. The one in my bedroom is rattling now, and I've had to move it as far away from the bed as possible, as it was disturbing my sleep. I'm just not sure what to do. The next delivery isn't supposed to be until Sept. It feels excessive to be only getting 4 months, and the drum rattle is truly annoying."

Cynthia (2/5)

"Fresh opposed to the cheaper one!!! Hands down a no brainer overall air feels better and can certainly notice the difference in smell if you have pets!!"

Brayden (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
