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.

Rated 5 out of 5 by from Great air pump and it is quieter than all others I've been using a Whisper 40 air pump as well as a Whisper 100 for the past year. The Whisper 100 has been powering my LED bubble wand, bubble volcano, and animated treasure chest with more air to add more things as needed (I put some entertainment in my 2 year old's show tank). I have some old pumps that I used to use in the 1990s and both are very quiet compared to all of those pumps. You need to make sure to put them on a level and proper surface for maximum quietness.

Rated 4 out of 5 by from Great Service I purchased a ex40 pump and it was great, has lots of power, and is quieter than a cheaper one I had. But it did break after a month, suspect some defect. I recieved fantastic service from Laura in consumer relations. She stood behind the product and got me a new unit within a week. Very impressed with the service from Tetra. Will definately purchase more products from Tetra

Rated 2 out of 5 by from Pump is noisy and short lived I purchased the pump a little under a year ago. The air flow was great at the time of the purchase but the pup was so noisy that I ended up putting it in a closet and running the air tubing through a wall, 3 datys ago one side of the pump stopped delivering air. I rerouted all of the tubing to be fed from the working side. Within 24 hours, it also stopped delivering air. I dismantled the pump and found the rubber diaphragms were cracked around the mounting screws as others had found. As a temporary measure I super glued the cracks. One side gave out within 24 hours but the other side is working 48 hours later. I found the repair kits on Ebay for around $16.50 but the new pumps are selling for $23. If the repair kits were about $5.00, the pump would be worth it, because dismantling the pump is easy and replacing the diaphragms takes about 5 minutes.

Rated 1 out of 5 by from Was wonderful for a month This airpump worked great and it was very quite. However after about a month it became incredibly noisey and it did not pump air affectivly. I wish Tetra would make better quality products.

Rated 2 out of 5 by from The pump is incredibly loud The reason I gave it two stars is because it's relatively inexpensive and works as it should. The downside is that it's so incredibly loud. I can hear the hum over my television or music, even when the volume is cranked. What's worse is that it's called the 'whisper' when it does anything but.

Rated 1 out of 5 by from My Tetra whisper 100 worked for less than 2 yrs It is generally a pump that can not last long. My pump suddenly lost pressure and then by opening it up, I found both of the rubber diaphragms cracked and teared. I thought i,m still cover under warranty for less than 2 years. However, the warranty specifically stated of not covering any rubber parts.

My impeller doesn't work

Asked by: Pdhowell
The link you provided was for an air pump, not a filter. It would not come with an impeller. I will email you directly.BREX

I need a pump to operate an under gravel filter (with two filters) and a mid sized bubbler Decoration. I need at least three ports. How many ports do these have?

Asked by: Marissa
Good morning,Thank you for your inquiry. Unfortunately, the large sizes, Whisper 60/100/150/300 all only have 2 air ports for connections. We do not currently have any products with three ports on them for your application. We would however, recommend that you use a power head to control the undergravel filter from Marineland (MaxiJet series) and then use an air pump to power the bubbler as needed.MINI

hi, i have a 20 galloon TALL aquarium. To use this for my filter, would I need the whisper 20 or 40? I have heard for a tall aquarium it is harder for pumps to push bubbles. thx!

Asked by: layne
It's one small airstone; but that airstone is the filter in my setup. I am using a biorb tank. So still the 20?

How to make a air pump work that set on the floor and tubing in the tank then the air stops working

Asked by: John Rodriguez
Make sure you are using a check valve to prevent water from backing into the air pump. If water backs into it, it will ruin the pump. Also, make sure you do not have excess amounts of tubing. You should only need about 6-8 feet total.BREX

Where can I get a check valve for this unit?

Asked by: Skoger
We do not sell check valves. They are typically sold through local fish stores, and pet stores where aquatic supplies are available. You will either find them where air pumps and accessories for air pumps are sold, or you may have to ask a clerk if the store keeps them behind the register.BREX
