Minimal noise, maximum air flow. The Whisper® Air Pump’s dome shape actually flattens sound wave frequencies. In addition, each model features sound-dampening chambers designed specifically for that model. And the air pump's rubber feet and suspended motor prevent sound waves from reflecting off surfaces such as tables and shelves.

Available in models for aquariums from 10 to 100 gallons, Whisper Air Pumps provide a powerful flow of air. UL listed.

Whisper 20 1 L/min

Tetra Whisper Air Pumps Help Keep Your Tank Quiet
Tetra Whisper Air Pumps keep your aquarium oxygen levels high, helping keep your fish healthy. And with seven different sized pumps, there is sure to be one that is perfect for your aquarium. This line of air pumps has a unique dome shape and rubber feet. This flattens sound wave frequencies and helps prevent them from reflecting off of surfaces such as tables and shelves, allowing your pump to produce minimal noise. Whisper Air Pumps can be used in deep tanks (up to 8 feet deep), and have enough strength to power long decorator air stones, multiple air stones in one or more tanks, and protein skimmers for salt water aquariums. Every Tetra pump also comes with a lifetime limited warranty.

Whisper Pumps Produce a More Oxygenated Aquarium
Tetra’s Whisper pumps will keep both you and your underwater friends happy. The pumps provide oxygen, which is good for your fish and tank, and also provide water movement. Combining these two benefits will lead to better water conditions overall. The underwater bubbles produced by the machine also add a mesmerizing touch enhancing the look of your aquarium. These pumps are the most powerful line that Tetra offers, ensuring that you are getting the best quality pump available.

Rated 2 out of 5 by from Tetra is falling off the top I purchased this pump for my 40 gallon to run two air stones. At first, I was very happy as I have used Tetra products for years now without complaints. However, this is a complete let down. It’s been a year and one month and the pump is loud it wakes my son up whenever he takes his nap by our living room (which is where the tank lives). I’m additon to being loud, it doesn’t pump any air out anymore. I had to replace it with another pump two days ago. What a totoal waste of money. The repair kit cost just as much as a new pump. I have older tetra pumps running just fine.

Rated 2 out of 5 by from Very Loud We bought a whisper 10 air pump a week ago, and it worked fine for a couple of days. Now it has a constant annoying hum/vibration. We replaced our first pump because it hummed and thought we needed a new pump. I guess that wasn't the case. We have tried everything to silence the pump. No luck so now we are on the lookout for a pump that is quiet. :(

Rated 5 out of 5 by from Extremely quiet!! I purchased the whisper aps 300 for my 180 litre tropical aquarium and it is very quiet. I had a Fluvel air pump before and it was very loud in comparison to this

Rated 1 out of 5 by from Brand New And Sucks! I bought this a couple of weeks ago and it doesn't pump air below the surface of the water. I have a ten gallon aquarium and the Whisper 10..... even at the top it has weak bubbles. It is letting out maximum air. I am very angry.

Rated 2 out of 5 by from Strange Problem I bought a Whisper 40 16 months ago. I use it for an air stone. Never had a problem. A day ago I heard a gurgling noise. What was all over the floor and the tank was one third down of water. I do have one way valve on it. I checked all tubing found no leaks. Tank didn't leak. I left the pump on and placed it on a table. That is when I heard the gurgling sound. The pump has water in it and I found a crack on the bottom of the pump shell.

Rated 3 out of 5 by from Great Customer Service I bought the Whisper 100 in Sept of 2017. It worked great for the first month or so and then started getting loud and then louder and louder. I've purchased many Whisper air pumps and this is the 1st one I've ever had a problem with. I called customer service and they sent me a diaphragm repair kit. Changing out both diaphragms worked for a few weeks but the vibrations and noise started again. This time my call resulted in the offer of a new pump. Sarah with customer service was great. Tetra products are great. Here's hoping they get the problem worked out with this air pump.

Rated 1 out of 5 by from Better box instructions I bought my kids a fish tank for Christmas. I bout the pump as well. You would think they'd tell you what's included & what's needed for the pump on the box. Instead I had to find out after I opened the box to read THE INSTRUCTIONS. Its definitely stressful putting a fish tank together for the 1st time, don't need the extra stress of having to make extra trips to the store. Not sure if it works yet bc I'm abt to go BACK to the store for what's not included. THANKS TETRA

Does these pumps go in the fish tank

Asked by: Lenora
Absolutely not, they are air pumps, and sit outside the tank. You attach airline tubing to the port and run it to an air stone or ornament inside the tank. BREX

How do I change the filter. The pump did not come with instructions.

Asked by: CC1972
If you are referring to the little air filter, you just pull it out. We do not sell that separately, only with a complete repair kit. You can use the original one to cut ones to fit out of a thin felt material. BREX

Even though I thought my tank was in a safe spot, my little sis somehow managed to knock it in my 20 gallon tank... Is it safe to try to use? I am draining it out as well as I can, it was brand new.

Asked by: lilyalisem
If it dries out completely enough that it will actually operate, yes, you should be able to use it. Open it and use a blow dryer to minimize damage. BREX

Hey there, new to fish tanks. Brand new unit and is really loud. Any suggestions, or return unit?

Asked by: Roach
Loudness can be due to how it is installed or an issue with the pump. Make sure you have chosen the right size pump for your tank and application. Do not go up in size as this will cause issues. If it has more than one port, you have to use both ports so tee them if you have only one air stone, for example. Remove any tubing not necessary, leaving only a very slight slack in the line of an inch or two. Call if you need more help, 1-800-526-0650. BREX
