I have this set of filters so I have two to switch between. I found that I wouldn't properly clean my vacuum cleaner filters with just one set. I went to sweep, noticed they were dirty and just brushed the dirt into the bin instead of cleaning them completely by rinsing with cold water because I then wanted to sweep and not wait for the filters to dry after washing. Now with two sets, if I notice they need cleaning, I can just put in another set and sweep on. They seem to be just as good as the original filters.
