I would recommend these filter pads. Review: Fit perfectly. You could make your own, but WHY? - These pads are well cut and fit my SunSun perfectly. Sure, I could buy a roll of filter fabric and cut my own, because, you know, I like to work with scissors. Beats watching the game. For the price I would buy these every time versus making my own. Maybe your time isn't worth anything. Balance out your purchase with Replacement Coarse Filter Pad for Sunsun Super Grech Perfect HW-304, Set of 3 , as ideally you want more course than fine filters. I place a layer of two course filters at the very bottom, topped with a fine filter. Do not place a fine filter at the top (ie very top, just under the motor housing) of your stack! A filter in that location will certainly keep the particles from entering the aquarium, but a the expense of trapping the particles in the rest of your media (biolgical, carbon etc). ## Features - 3 White Pads and 1 Blue Coarse Pad - Fits SunSun HW-304B and other re-branded canister filters - Dimension: 8.5” (L) x 8.5” (W) x 0.75” (H) - Provides both mechanical and biological filtration ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,128 Reviews | ## Images ![HW-304B White Blue Pad HW-304 Canister White and Coarse Filter Pad - Image 1](https://m.media-amazon.com/images/I/81EetFd123L.jpg) ## Questions & Answers **Q: Can I cut the pad to fit the sunsun 402b?** A: not sure but I believe so, I orederd these & they were the wrong size for my filter.
