[This review was collected as part of a promotion.]  OK to start off neither have I, nor any of my family members ever owned an air purifier in any of our homes but after I open this product, set it up and begin to use it, I now recommend this to not only my family but my friends, because the things that I saw that this purifier was cleaning open my eyes to what I could be breathing. For starters cooking is a medium threshold in this house, but upon introducing any kind of perfume or any kind of allergens or any heavy chemicals used to clean the house, this purifier would let me know immediately of what was going on. .
