DEPEPE 10pcs 7.8 x 5.9 Inch Aquarium Filter Media Bags with Zipper for Activated Carbon, Biospheres, Ceramic Rings

They have the finest mesh ever seen. No pieces of carbon or zeolite getting through these. Unlike years of others!Great size, price, fast delivery. My turtle and tank much appreciate!🐢😃

These bags are very nice and of good quality. The zippers work smoothly and completely close to avoid spillage of the bag's contents. I am using one to hold activated carbon that I placed inside the filter box on my 40-gallon aquarium. None of the carbon has leached out, and it is doing a lot of good for my tank. I am very pleased with these bags.

These filters worked exactly as expected! They kept the water clear, helped reduce odors, and genuinely improved the overall environment in the tank. I noticed my fish seemed more active and comfortable once they were in use. Installation was easy, and they fit perfectly without hassle

Pretty sturdy has sharp substrate in it didn't tore. 2 different color types. I liked the black one

Versatile use of bags. Handy for small or larger items. Washable. Good price. Arrived on time and well-package.

Fast delivery, no issues at all with the order. Everything was just as promised.

I used these for some desiccant beads for my 3d printer filament storage. They hold the beads well and none are able to fall out through the wholes or along the zipper.

Not fine enough for purigen, dont make the same mistake I made. Should work for most other media's, but I bought simply for Purigen and the price tag.
