Bought 4 of these little worthless items plus 4 replacement filters plus the lifetime warranty!! I spent $360 to get the shaft!!! Emailed them and have not heard anything back. Doubt if I will. So I am going to make a complaint to the Attorney General office of the State of Oregon and see if they can get some results and shut this fraudulent company down! And hopefully get my money back!!! Denise B. User's recommendation: Don't waste your time or money!! Total fraud!!
