I love it so much I bought another one. The Pure Enrichment PureZone Halo HEPA Air Purifier is a cootie killer! If you have allergies to dust, pollen or dander, this is going to be a game changer for you. My youngest teen is allergic to everything and this has helped her sleep better without a doubt. Regularly $100 and discounted to $59.99. NEW shoppers (or create a new account with a new e-mail address) enter HSN2022 to take an additional $20 off at checkout. The price drops to $39.99 with FREE shipping!
