I got sent this NeverChange Air Purifier from Shark completely free and I love it. Living in such a dry place like I do with such dry/dusty air it helps keep the air cleaner and healthier to breathe. I spend a lot of my time in my house so making the space I spend so much time in easier to breathe in is bonus for me! I love the scent feature on top which you snap/twist in which ever odor neutralizer scent you prefer and through out the day the machine purifies and adds scent to your home!
