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

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!

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

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

This filter foam sponge is a great addition to any fish tank. It does an excellent job of trapping debris and maintaining water clarity. The only reason I'm giving it 4 stars instead of 5 is that it can be a bit difficult to clean. The foam is quite delicate, and I found that I had to be careful not to damage it when rinsing it out. But overall, it's a great product that I would recommend to any fish tank owner looking to improve their filtration system.

Works good

Just what I needed.

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

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