Tetra Whisper Internal Power Filter Description
Tetra Whisper In-Tank Power Filters provide the ultimate in convenience and quiet. These filters mount on the inside of the aquarium, rather than hanging from the outside - making it possible to place the tank flush against a wall.
- Motor is under the water for extremely little noise
- Functions in as little as 2 inches of water
- Includes one pre-assembled Whisper Bio-Bag filter cartridge
In-Tank Filters are unusually quiet, since the motor is under the water. Offering the same quality and performance as an external filter, the Whisper In-Tank Filter will function in as little as 2 inches of water - making it ideal for turtle tanks, or for creating a waterfall inside the tank.
Whisper In-Tank filters adjust easily to high or low water levels with mounting suction cups and/or clip. Each filter includes one pre-assembled Whisper Bio-Bag filter cartridge and mounting clip.

Tetra Whisper Internal Power Filter Customer Reviews
It is the only brand of filter I use and will ever use very dependable
I have one 40i and another (green one) that's similar but not as good. When the green one died, I made the mistake of buying a Cascade. Never again will I buy anything but a 40i. I had no idea how great this filter was until I tried something else. I spent more money on a filter that I do not like. Lesson learned. Only Tetra 40i's from now on!
These are the only internal aquarium filters I will ever use. They keep the water crystal clear. If a power outage occurs, they will restart in very little water. I almost had a house fire because another filter would not restart and the motor overheated. They come in three sizes. Perfect for any aquariust.
I have 6 aquariums. I have used the Marineland Bio wheel filters. They are expensive to replace cartridges and always having to take apart for cleaning and repairs. I have replaced some with Tetra 40I and love them. They are super quiet; a fraction of the cost for cartridges (I make my own). I have two in a 55 gal. And two in a 45 gal. When I can afford them I am going to order 4 more for other tanks. The best inexpensive filter yet.
This works perfect for my 2 turtles I went overboard but it keeps it clean! And smells good!
I have been using tetra Whisper filters and bio-bags for years. I have an aquarium and I have a turtle tank with four turtles. I use 3 intank whisper filters in the turtle tank and they work great!
THE TETRA 40I IS THE BEST FILTER I EVER HAD . ITS VERY EASY TO CHANGE.
We bought the pf-40i and a pf-20i and for our 55 gallon tank. They are working great and are so... quiet. They are also great because they take up no space on the outside of tank.
I purchased this in tank filter after my regular filter leaked on my hardwood floor twice. Very quiet and seems to do a good job. Excellent filter for the price.
This is a great filter we use them on all our turtle tanks!
I have two Tetra Whisper 40i submersable filters and I love them. I have a 55gln aquarium with lush plant life and many beautiful fish and thanks to the Whisper 40i I am gettig better results in this aquarium than I have with any other filter product.I definately recomend this submersable filter for anyone that wants great results for their aquarium and for a long life for their loveable fish buddies.You have to have one...or two. Heck I'm ordering another one for my 29gln aquarium today.:)
I purchased In-tank filter 101 and 401!They prove excellent filtration for two tanks, one a 10 gallon and one 45 gallon which each house a turtle. Turtles put out a lot of waste and these filters work the BEST I have ever used. The ease in which I can change the filters is wonderful!
I left my bio-wheel filter in South Carolina when I came home for the summer, and needed a cheap filter. I bought this one, and discovered that it is just as effective as my biowheel. There is plenty of space for beneficial bacteria to grow, and it clears the water out BETTER than my Penguin filter. I was very suprised. I would recommend this to anyone. When I get my other filter back, I'm going to use both of them to keep the tank clean and extra healthy. An amazing and cheap filter - great for all fish.
I love this thing all I had to do is open the box put the cartridge in then plug it in. It was that easy it cleans great and quietly too. This filter is great for the money :)
