Particularly if you are a Canadian, do not buy this! I ended up paying $165 CDN (with two extra filters at $20 for both), and I had bought only one unit, would you believe? I agree with what other people wrote. You will just throw your money to the garbage!
I am very disappointed. I should have read the numerous negative comments before buying Arctic Air that I should rename Africa Air and not being far from the very truth!
Bottom Line: No, I would not recommend this to a friend
