Perfect fit for the Aqueon Quiet flow 300.
These are meant to be changed once per month and they do a great job of filtering debris out of the water and keeping it clear. Theyâre very easy to change, as they just slide in and out of the filter unit. The price was very reasonable. I would definitely recommend Aqueon products.

A filter you can rely on.
Buying these Aqueon 12 pks. Which I couldn’t find in my favorite pet store, is actually saving me money.The filtering quality is great which means I only have to change the filter once a month. Changing filters are easy, pull used one out, slide a new one in.

Fit well. Proper replacement.
These fit and work well, but in my opinion are pretty expensive. I usually rinse them off under a powerful sink several times before I replace them with a new one. Seems to work for me.
