I order a lot of things online so it would be helpful if you were specific about the product that you supplied to save me having to research it. In this case it was an electriQ Antiviral Air Purifier 7 stage cleaning with True HEPA UV TiO2 Ioniser. This is a lovely bit of kit. Well made, virtually silent on sleep mode and the built in Ultra Violet lamp claims to deal with viruses. You really notice the fresh air affect even with windows closed. Delivered early next day. It has been on continuously since it arrived. Well done, I'm thinking about getting another one.
