6-Pack, Size B, Rite-Size Cartridge Refills

About the only kind available. Soooo

The box was completely smashed when it arrived. It was sent in a plastic bag instead of a box. Most of filters seemed ok but the little “filter rocks” were everywhere. I’m assuming it will affect the quality somewhat.

My fish are happy so I am Happy! Thank you

It’s a great product, I’ll keep buying for my tank but Last two times I’ve gotten it from Amazon the box comes crushed and one of the filters are broken I would have sent it back I needed to change my water in my tank.

They fit in the fish tank

These are all standard products function as expected

Ive used these for years and are a fair value when bought in bulk.

Love the filters

It does not fit as described for my model

Great
