CMP B-43 Plus Filter Saver Pack
The Filter sock removes dirt and debris before it can get to the filter. This allows your filter to run a little longer between cleanings. Makes filter cartridge cleaning much easier and a lot less messy. When soiled, just toss it... or spray with a garden hose. Each can be reused several times, if desired. Fits any shape skimmer basket.
