Not as pictured

Product not as pictured. Overwhelming Powdered carbon dust made filters black and is difficult to rinse out. Buying these for years and never have I come across this.

Filters are appropriate, priced the same as other sites, wish you would offer size large.

i love chewy but.... disappointed this time.

i love chewy and i will continue to use them but i bought quite a few of these and there is charcoal matter everywhere and all over the white part of the filter. i am going to try to clean it up a bit but i don't even know if they are usable. we shall see. disappointed. i think it was not tightly packed enough

Fishy Filters

These filters have always been great. The last batch was defective, activated charcoal spilled everywhere, but usually this is a great no fuss product. Chewy makes saving and reordering pet supplies a breeze.

Tetra Whisper Bio Bags

These filters are perfect size. They were half the price at other big box stores. Delivery was only 2 days. Always use Chewy for all my supplies.

Best Filter

The filter for the quiet tank filter fits perfect and is easy to use. There’s no problem putting it in and when it’s time to change all you have to do is pull it out and replace with another. It can’t get much easier than that!!
