I ordered a replacement filter but it just doesn't fit as well as the original filter and made the vacuum more difficult to assemble. It used to take 30 seconds to disassemble, clean and reassemble the vacuum cleaner. Now I have to fight to get it all back. The plastic part at the top of the filter is a bit longer and interferes with snapping into place. and there were times when it came loose when vacuuming and whatever I picked up ended up back on the floor.
