My mother has a Shark vacuum cleaner. She likes it very much. However, the filter is aging and looks fairly familiar. Mom went to all the shops to find a replacement filter. When she found them she thought they were too expensive to buy. I told her I could find her on Revane and she said come on. We found what we were looking for and bought it. They were less than what you would pay at most stores. This is IF you can find them in stores. Looks like the filters worked. Mom hasn't told me anything since we got them except "They fit! Many Thanks!"
