Really good air purifier that has an app too for remote control. Looks immaculate to me, no dust that I can see. Was purchased from Amazon Warehouse (guess an unused return) and used in our empty office for a few months. Filter looks brand new to me but is used, and is reported as needing replacement, which is an easy purchase off eBay. Weight of package 8.5kg, this is a proper sized unit, not a tiny desk one: 52cm H x 31cm D x 28cm W
