Polyester material filter bag with pull straps for the Vortex D-1 diatom filter. Can be periodically cleaned. Review: Great filter - This is the best filter to really polish up your tank and it makes it crystal clear. I will say it can be a bit messy to change the filter media. Once change the filter media once or twice you get the hang of it Review: Great filtration - I have used many of these these bags in 2 diatom filters for gravel cleaning for over 35 years. Great filtration when used with the diatom powder. I would recommend using a coating of aquaium silcine on the filter around the plastic neck at the top as that is the area prone to wear over time and holed develop if you take the filter on and off a lot. The silicone will help you get better milage.

Really Cleans the Water
If you need this filter then you need THIS filter. The old school setup with the glass mason jar is a little unnerving but man does the Diatom filter clean tank water. amazing clarity. 10 thumbs up !

perfect
worth every penny as a replacement for the original filter bag. I have been using these filters for 10+ years now have never seen something that works as good at polishing the water.

Had original 10 years
Restores efficiency to the filter. Really you can't replace this filter with any other product. It's one of a kind, and they last for a very long time.

Diatom filter replacement bag for D-1
Bag was not 100% sealed. Tried using super glue to close about a one inch opening in the bag. See how long it will hold together?

Do yourself a favor and buy the Magnum water polishing filter it is just a good if not better
Do not buy this product as well as the D-1 Filter. It should not be sold as it is not ready for production. It worked for me just once and then the Motor went dead! I really did want this to work as I had one years ago! Do yourself a favor and buy the Magnum water polishing filter it is just a good if not better.
