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

Perfect fit and great amount so I dont run out.

very good.

Quick transaction and perfect for what I needed ! Thanks

Works well

Nothing beats the OEM original stuff!

These fit perfectly and the price is great

great colors and clear water

works in aqua-tech filters also

In this last shipment, the carbon had shaken out of the filters and was all over the inside of the shipping box. Usually thats not an issue. Kinda messy.

Great price works great
