Last year I was given a hand held vacuum (which uses these disposable replacement filters) but it only came with one filter. I clean this filter every time I use the vacuum, but I haven't actually changed/replaced the filter myself since I got the handheld vacuum. I was nervous that these filters might not fit my particular model but they fit perfectly and while you can definitely tell these filters are not as well made as the original/branded ones they still work very well and are great Filter. Replacement - I would buy again!
