Tetra Whisper Air Pump with Minimal Noise and Maximum Air Flow

I recently purchased the Tetra Whisper Aquarium Air Pump, and I must say it has exceeded my expectations. This air pump offers fantastic value for the money and has proven to be a reliable choice for my aquarium needs. First and foremost, I appreciate the affordability of this pump. It is competitively priced, making it a great option for budget-conscious aquarium enthusiasts like myself. Despite its reasonable cost, the quality and performance of this pump are outstanding. While the name suggests "whisper" quiet, I have found that these pumps are not completely silent. However, they do operate quietly enough for my needs. I can comfortably enjoy the peaceful ambiance of my aquarium without being disturbed by excessive noise. It strikes a good balance between functionality and noise level. One of the standout features of the Tetra Whisper Air Pump is its versatility. It is suitable for a variety of tank sizes, including deep tanks. I have always opted to purchase one size up from what I actually need, and it has worked exceptionally well for me. This flexibility ensures that you can rely on this air pump regardless of the size or depth of your aquarium. Durability is another aspect that impressed me. The Tetra Whisper Air Pump has a solid build quality, and it has lasted me around 4-5 years on average. This longevity is commendable, especially considering the price point. It offers peace of mind, knowing that I won't have to worry about frequent replacements or malfunctions. Overall, I wholeheartedly recommend the Tetra Whisper Aquarium Air Pump to anyone in need of a basic, yet reliable air pump for their aquarium. It provides excellent value for the money, operates quietly enough, and is suitable for a range of tank sizes. With its durability and longevity, it will surely become a trusted companion for years to come. 🐟🐠🐟🐠

I first began using Whisper air pumps as a child over thirty years ago. (Back then they were tan and the air filter could be popped out.) They were the best then and I am pleased to say that I find them to be the best now. I am using the Whisper 20 for an over stocked ten gallon tank. It is working very well to supply a large air stone. This pump was a replacement for an identical pump that was eight years old. The old pump had lost its power, but it was still going strong and it was ever so quiet. This new one is doubly powerful. I had no idea I had lost so much performance with the old one. I know I could have purchased a parts kit to fix the old one, but it was just easier and less hassle to buy a new one. The new pump is slightly louder than the under performing old pump, but the difference is negligible. I would expect no less of a brand new replacement device with about double the output of the old device. I am very happy with my purchase. I highly recommend this product for performance, longevity and silence. UPDATE September 30, 2021 - Just a few comments concerning longevity. I have purchased this pump from Amazon three times. This most recent third purchase a couple days ago was to replace my second pump which LASTED OVER 7 YEARS!! - That’s a pretty good run. While the old pump still did work, it had developed a terrible rattle. I noticed the new model says it’s for 10-30 gallons as opposed to 10-20 gallons like the older model. They’ve updated the color from blue to charcoal gray. (See my side by side photos of the old model on the left and the new on the right.) - I think they have phased out the 10-20 version. I didn't notice a change in air pressure on my tank. HOWEVER, IF YOU ARE CONCERNED ABOUT THIS PUMP DELIVERING A HIGHER PRESSURE, PLEASE NOTE THAT THERE IS NOW A VALVE INCLUDED TO ADJUST PRESSURE. And THEY HAVE NOW INCLUDED A CHECK VALVE. It’s really about time they did that because it’s a cheap fix to prevent tank water siphoning into the pump if the power goes out. That’s a disaster in the making. The valve even has an arrow to indicate which way the air flow should go (please notice my photo). If you are new to keeping fish, for safety reasons: Please keep in mind to always use a check valve, no matter where you position your pump.

Smooth airflow and very quiet. Great, compact size for my shelf.

I have purchased 5 of these pumps. Still using them all. pretty quiet. Strong air supply. two of the pumps started pumping less air over time. That's one of the reasons I bought new pumps. the repair kit for this pump is $15 and the new pump is $20. But after a second pump went out I did buy the kit. One side of each pump started to be very weak. Thought it was going to be a bad rubber pumper but what went bad on both units was the outlet check valve. the small silicone valve wore out and didn't keep the air going in the outward direction. So, one repair kit fixed the two pumps. replaced the bad parts but kept the rubber plungers for when they might go out later on. Still, $15 for the repair kit vs $20 for a whole other new pump... tough call But, one kit to fix two pumps, I am okay with that

Great price, I bought this item on sale for 9 dollars, it works great. It is really quite, at full output. Now full output for me was a bit too much. I used the adjustable flow rate to decrease output. Now one thing I did notice here is when you lower the flow rate it gets louder. Now its not loud or anything of the sort but it gets louder. If you twist rapidly to change the flow rate it starts to vibrate more, and if bumping against something it can get loud. After playing around with the adjustable flow rate, I notice if I adjust the flow rate slowly there are no vibrating issues, and as long as its not hitting something on the site you won't hear it. The bubbles it produces is louder than the motor itself. Where you set it depends on the noise itself. Its a rotating motor, so if you put it on wood its going to sound like your phone on vibrate. * Buzz buzz*. I set mine on my desk on top some cloth. No issues what so ever. Great price. *Note does not come with a check value* If you set it below the height of your tank, and you turn off the motor, it may be possible for water to leak back in and damage, or make your motor much louder. Two solutions, place this air pump at least 12 ft above your max water level or use a check value (about $2)

10 years and 6 months. This is how long this air pump has lasted ---- so far. It's been sitting outside half of that time. Still very quiet and working fine. The only thing that has broken is 1 of the 2 air outlets that broke off about 3 years ago. Guess the plastic aged a bit too much. But air continues to come out of that little hole. I only need 1 of the 2 air outlets for now for a small pond but can glue air tubing directly on there any time if needed.

I do some fish/shrimp breeding and own about 5 of these pumps in various sizes. After years of running them here’s what I’ve found. 10-30 gallon (2 stars) ended up sounding like a tattoo machine after an hour so I returned it. 20-40 gallon (5 stars) these are hands down my favorite. Super quiet. I’m sensitive to low humming noise in my house and you can barely tell they’re running. 30-60 gallon (3 stars) a workhorse but also a little on the loud side. About the same sound level as the 10-30 gallon. 10-30 gallon tested at 68dB at 1” away 20-40 gallon tested at 62dB at 1” away 30-60 gallon tested at 69dB at 1” away Interesting how the small pump puts out the same amount of sound as the larger one but it’s just how they are. If you’re on the fence about one because of the reviews about noise trust me, the 20-40 is the one to go with. I own two and they’re both pretty quiet. If you’re using in a dedicated fish room or breeding in a garage etc the 30-60 pump probably won’t bother you. But for anyone using the pump in their house or office etc I strongly suggest the 20-40. I thought maybe I just got a quiet one, but both of mine sound exactly the same. Even if you’re using it in a smaller tank, just get the 20-40 and dial it back with the adjustable valve it comes with. If you tried the 10-30 pump and didn’t like it because of the noise, try the 20-40 before convincing yourself they’re all loud. Hope this helps!

Its always a hit or miss with a tetra air pump, they're either gonna be completely silent and be a work horse, or be extremely loud and worthless. I personally think its worth the risk, but if you want a consistent brand i can't recommend this.

Es una bomba excelente, buena potencia para las piedras aireadoras de 15 cm de largo. EL nivel de ruido es casi cero, si está en una superficie firme; de hecho, es prácticamente cero cuando la suspendes en la mano. Me encanta porque por la noche no produce ruido que genera ruidos que afecten conciliar el sueño o lo interrumpan aunque esta a unos 10 metros de mi cama.

Produto realmente EXCELENTE! ZERO RUÍDO!!! Impressionante.

I previously had several Aqueon QuietFlow Air Pumps and while they were good generally, the last one did not last as long and got very loud, burned out 2 outlets on my powerbar and in the end, I replaced it with this pump. It is very quiet and functions well for my 20-gallon tank (with an sponge filter and airstone)

Better do not buy this item as it makes too much noise. It is as if you are running an IC engine after removing the silencer! I opened the pump and saw that the diaphragm holding vibrating arm has not been cut to corret size and it was hitting against the body of the pump which was causing the loud noise. Even if this problem is resolved, the vibration of the pump is simply unbearable! There are other pumps in the market almost in the same price range and are lot quieter and with less vibration!

Just set up this air pump and I am SO happy - I can't hear it because it's quieter than my filter; before this, I was using another air pump which drove me absolutely crazy - had to turn it off at night because it was too loud. It's a little bigger than my old one but given how quiet it is, I don't care that it takes up more space. It's also extremely strong, lots of air bubbles coming out compared to my old one (which worked fine but there is a very noticeable difference between the two). It come with a control valve, so if you don't want such strong circulation, you can always attach and adjust air flow accordingly.
