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

Excellent for Aquariums

I like my filter that why I buy it its cheaper then store

VERY DISAPPOINTED! I order these somewhat regularly and have NEVER had this issue. They are always on a plastic bag (not these). The carbon was all over everything in the box i received, including my white Sleep gown. Thankfully I was able to save the gown. The price is great however these appear as re-dos...not brand new...

Great value

These are all standard products function as expected

Muy buena calidad y pronta entrega

Nothing beats the OEM original stuff!

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

It sit and works perfectly

These fit perfectly and the price is great
