Tetra Carbon Filters for Whisper EX Power Filters Medium by Tetra

I order frequently from Pet Mountain and have always been pleased w/prices and service ( and sales too!) Merchandise is A+ and sent to me fast.

Just as pictured. great price.

My dogs love these products. Dingo makes great chews and Pet Mountain has great prices. Fast shipping!

Have used these filters exclusively for many months now. We have 7 fish that are all doing very well. 2 were born in the tank and are now full grown female adults (one is an orange-yellow plattie, the other a brick-red plattie), the other five are 3 cory cats, 1 good sized algae eater, and I still not sure what the 7th is, but is about the size of a small guppie. We no longer have the "parents" of the platties. The one mother was given away and daddy died, and the one over a year old I believe her mother died, and Daddy was given away. The 7 have all been healthy except for one brief period where the red plattie seemed ill, but recovered well.. I change about 25% of the water with filtered water every 1-2 weeks, along with 2 new filters; this seems to work very well for these little ones, and they all get along great!

My pump for my 30 gallon goldfish tank takes these filters. Very reasonably priced.

The filters we ordered were MUCH cheaper than a competitor website website and they were here in no time. Will definitely order from here again!

I have purchased these filters twice and am very happy with the low price as well as the reliable service, thank you! Highly recommended!

Just what I needed at a great price!

After so much searching for filters at a reasonable price, I have found out that if one buys in bulk, you can save a little money in the long run. PetMountain has it. Not only in aquarium filters, But in all your needs for your fish tank. Thank You Pet Mountain.

Only bought replacement filters so nothing special about them except that we got them for a good price and transaction went smooth.

I normally buy my filters for all my aquariums in stores but after I found out how much I could save by buying these filters in bulk, I've never gone back to a store for filters again. Wooo!

I purchase a year's supply of these filter cartridges when I buy them. Pet Mountain always has the best prices.

Tetra filter cartridges are efficient and economical.

If you need these filter pads and don't know how to make your own, this is the lowest price I've found.

It works very well and came with everything described.

Smooth order and delivery, well done.

I like these better than the kinds with the frame where the carbon pellets tend to escape if you try to wash it.

I wish i had purchased an undergravel filter for my new aquarium. It would be much quieter and I would not have to keep purchasing disposable filters. The filters themselves are fine - great price here compared to the big box stores.
