Filter Socks & Holders

Filter socks are designed to trap free floating particulates from your water. They come in many different types and sizes, with the most common being a felt 4" or 7" diameter sock. Many sumps come with a pre-installed filter sock holder, but in some cases you may need to add your own which can be clipped onto the side of your sump or customized further based on your needs. We really like socks with plastic rings since it makes removing them from the holder a breeze and their is no draw string to tie and can eventually come loose.
