Review on EnviroCare Premium Replacement HEPA Filters for Royal Dirt Devil Type F1 Bagless Upright Vacuum Cleaners by Bonnie Nieves

Now that my vacuum cleaner has a new filter, it's happy again. It sounds better too. Be sure to replace the filter in time. Pay attention. Your brochure tells you when to replace the filter, but it's in small print. look for it. Mine says every six months. I think four or five months to replace it. I'm sorry I was late this first time.
