The Penguin Refillable Media Cartridges are better than media bags, the patented ribbed design keeps the media of choice evenly distributed for maximum water-to-media contact, and the snap open and lock tight design ensures no media spillage.

Easy to Use by Eco Friendly II07/30/2012
Easy to fill with the media...works well and no more throwing all the plastic away as with the standard filters!!
Buy Now!! Don't Wait. by BuzzStPoint11/07/2012
Can't believe I waited so long to buy these. I bought 2 of them, one to fill with charcoal and one I filled with poly fiber. No more of the expensive cartridges.
Awesome Product by ItchyNissan from Federal way wa01/07/2012
I purchased this product so I would not have to buy the ones that are not refillable. I purchased 2 because I noticed 2 slots in the penguin 200 filter. The filter cartridge is great. It's sturdy, holds a lot of media and fits perfectly. The price was awesome and the shipping was really fast. I purchased them and got them on the 2nd or 3rd day. I can't remember but I think it was the second day. Great company to buy from. I was satisfied and you will be to.
