I have been checking out air purifiers for a long time and they are really pretty pricey. Daily Checkout has a Plug In Silent Air Purifier With Nightlight for only $5.99 for today, 12/26 only. It’s on the smaller side which is nice to keep in the bedroom as well as the fact that it has a “whisper quiet fan” that won’t keep you up at night. Shipping is $4.99.
