Hipanda Filter Foam Sponges, Bio Sponge Filter Media Pad, Cut-to-Size Foam for Aquarium Fish Tank (9" x 9" x 1",2pcs)

These filters worked perfectly. Lots of comments about not being thick enough, but after soaking and rinsing expanded just fine. Tough, and lasts through multiple cleanings. 75gal freshwater tank with 2 large HOB filters. Will buy again if needed.

Nice value and more than enough for my needs. Can cut to size needed and filters the water great. Should last a long time. I had more than enough for extra filtration. Water is so clear that I haven't even used the charcoal filter the my pump came with. All plants and fish are doing well and rarely change water

Works good

Unlike some other people, I appreciate that this product is vacuum sealed. Takes up less room than the huge bundle of filter floss I have!After letting the product sit in some water, it does rise, but I wish it was at least 1” thick, but it’s not. Still works great, though. I’m able to reuse it when I use filter floss with it. The floss does seem to do most of the work, but whatever it doesn’t trap, this little sponge does.

Great value and word great in my filter. Very durable and easy to clean. Amazon home delivery was very convenient

Once soaked in warm water these filters expanded to normal size in just seconds.I cut to size and used them as vacuum filters.

I couldn't find an air filter for an old Snapper mower I have so I bought this and cut it to match the breather. Then I put the lid on an let it expand overnight. It worked perfectly!

There what i wanted but a little bit too thin its a nice big sheet of 2
