Product review (5 stars): You can stretch the use of your filters by. Gently hand washing them.
Had mine 5 Years! Never had a problem til yesterday. Stopped running in middle of cycle. Opened back, checked the inline fuse per the schematic on side of unit. Fuse was SPENT. Got a new one in, and runs great again. Definitely got more than my moneys worth for it. I also custom made my own to fit the dryer vent. A good idea to clean inside the rotating circular screen filter free of lint. By wiping it with a used dyer sheet. Definitely buy extra filters!
