Tetra Whisper Ready-to-Use Disposable Filter Cartridges for Aquariums, Large, 1 Count

I have a fish tank and clean it each month and always purchase these filters, they are great, the price is good, not expensive at all, all come individually packed, which is great, at the end of each month they seem to catch on a lot of fich tank ''dirt''. I like them, use them all the time, great product!

Good filter for the aquarium.

Fits my filter perfectly and is carried in my store at Walmart.

I actually use these in a small outdoor pond so it has a big job to do. I know you aren't supposed to rinse them out a reuse them, but I do and have never had a problem. Since it's outdoors, it gets filthy fairly quickly so I spray them out to extend the life of them but still replace them once a month.

These filters are the best! The work perfect with my tank and keep it looking clean for months! I can go at least two months without changing it sometimes! High quality and I highly recommend.

Very absorbent and easy to replace

Great filter. Work's beautiful. It is the only one I will buy.

Great item works well and the price even better

They are great for my filter. They help me keep my turtles tank clean. I need to buy more lol

It works for our 20 gallon tank filter just wish it would offer 2 in a bag instead of 1 like other brands I purchased. But I think it doesn't filter as well as the other I have purchased before.
