Awsome Price

I have only found one pet store that carries this style of filters and they are over 3 times the cost of the filters here. I always have one box extra on hand and the price is so cheap I have to keep my self from ordering too many!

Great cartridges, great price.

I have been purchasing these cartridges in the 6 pack form from Pet Mountain for about a year now. The cartridges perform well, can be rinsed and re-used a few times before replacing. Pet Mountain's price on these cartridges are about 1/3 of what that are locally (even with shipping!).

Good Filter Cartridges

Good filter cartridges at a great price from Pet Mountain.

Harvey, Milford CT on 04-16-2010
Excellent Service

I ordered these filter cartridges and received them without any problems. Excellent company to do business with.

S, Sterling VA on 12-03-2009
No surprises

A simple and straightforward order for filter cartridges. I have ordered from Pet Mountain and as previously the order was correct, neatly packaged and received sooner than expected. All I ask for in a simple order is simple service, to receive what was requested, expedient shipping and clear communication in the event of a problem. Pet Mountain has easily fulfilled my expectations and I will order from them in the future. S.
