Worked amazing, I loved it, but the only issue I had was then I had to plug the cord into the air purifier. It was very lose so the purifier wouldn't turn on. Had to hold it in for it to turn on hope that nothing would move it so it wouldn't turn off because it was a hassle turning it on. But other than that it made a big difference in the air the first day. But I didn't want to keep fighting with it so I returned it.
