Review on 2-Pack Tineco A10/A11 Hero A10/A11 Master PURE ONE S11 Series Cordless Vacuum Replacement Pre Filters by Bill Sorenson

I needed a replacement filter for my vacuum cleaner so I could keep vacuuming while the other filter was being washed and dried. Simply wash this filter in the sink and let it dry. I usually let the filter dry for 24 hours. It collects dirt and needs to be washed, so I needed a backup filter.
