I was given this by Influenster in exchange for a review. I've been using it for about 3 week so I could give a more thorough review. It definitely helped filter the air and we notice a difference in our allergies when it's not on. Smoke from cooking dissipated much quicker than normal. As you can see in my picture, having the air purifier running showed us we had an issue with our furnace so I'm thankful for that feature.  I don't think the odor neutralizer cartridge lasts as long as it claims though. I do like the fresh smell of it, it's light and didn't irritate my allergies. I will probably invest in another one in the future for the upstairs.
