Filter Socks

Discover an extensive collection of aquarium filter socks and pond filter bags at Finest Filters. Whatever you’re looking for, we’ve got filter socks to suit your fish tank or pond. Our filter socks come with welded plastic rings, and are ideal for using with a sump tank. Meanwhile, our pond filter bags typically feature a drawstring, which allows you to tie the bag around the gravity return pipe to your garden pond.

You can choose from felt filter socks, nylon filter socks, pond filter bags, and filter sock holders, depending on your needs. Felt filter socks are among the most popular options, and we have them available in 100 and 200 micron ratings. The nylon filter socks in our collection come in the same choice of ratings, and it’s worth bearing in mind that they can be much easier to clean than felt filter socks.

Find pond filter bags to use with a gravity return filter to help remove particulate waste from your pond. These bags are even able to remove smaller waste particles that may have passed through the first mechanical stage of filtration. What’s more, you can keep your filter socks in place with our specially designed holders for aquarium filter socks. Shop either 4 inch filter sock holders or 7 inch filter sock holders in our collection, depending on the size of your fish tank filter.

At Finest Filters, you’ll find a wide range of aquarium filter media and pond filter media, featuring filter socks, Japanese filter matting, air stones, filter brushes and more. Browse our full collection today.
