I’ve never owned a Air Purifier before but thought that this could help me get over being sick (if it was in the air) since I have been for 2 months already. Well we put it together the day it arrived, which was really easy and started using it right away. The air felt cleaner and I actually started getting better. I can’t express how much I love this machine, as far as I’m concerned, it was the BEST decision I’ve ever made! The reviews from other satisfied customers is what prompted me to give it a chance and I have NO regrets.
