    • They fit great
Size: Large Style: 1 Count
They fit great and the whisper filter. They say they last for a month but I usually change mine every two weeks it’s not been two weeks yet, but so far everything seems to be working well and my tank is a lot cleaner.

    • Perfect fit
Size: Small Style: 6 Count
Got these filters to replace the one on my granddaughter's fish tank. This is the better buy than some other options on here. Just take it out of the package, run it under the faucet to remove any excess charcoal, and slip it in the holder. Make sure you get the right size for your tank. Really, so easy to use. ... show more
