What is an Aquarium Air Pump?
Aquarium air pumps are a piece of equipment that delivers oxygen to your aquarium. Air pumps are external devices. They need to be placed outside of your aquarium, which means they are not waterproof. The air they generate is delivered through airline tubing. You can use accessories like air stones and bubble decorations.
Air stones can distribute oxygen while bubble decorations add interest to your aquarium. They work in both freshwater and saltwater tanks. For saltwater, they tend to be use with wood stones in applications such as a Protein Skimmers. Since saltwater fish tank need to have more current than freshwater fish tank, a wave maker is a better fit for them.
The mechanics of an aquarium air pump are actually pretty simple. You have a magnet, which is the tan colored part above that turns on and of. As the magnet turns on and off, the lever on the bottom left of the photo moves up and down. This movement from the level pumps the rubber part in the middle called the diaphragm. The diaphragm is the part that takes in air and pushes it out to the airline tubing.
Do I Need An Aquarium Air Pump?
The main reason to get an aquarium air pump would be to provide oxygen in the tank. The most common application for an aquarium air pump are either with fish that need rich oxygen. Discus (due to higher temperatures) or Goldfish (Due to their size) are two examples. They are also great to use if you want to connect them to a Sponge Filter or Air Pump Powered Protein Skimmers.
Aquarium Air Pumps versus Wavemakers
I do get this question a lot. Why should I get an aquarium air pump over a wavemaker. Aquarium Wavemakers are great solutions for water movement and aeration. Yet, they are not for every aquarium setup. In freshwater tanks, there are certain setups where an air pump is more appropriate. For example, fish like African Cichlids need current. Other fish like Goldfish and Betta Fish, want calmer waters. With an aquarium air pump, you can have oxygen rich water without having a current that is too strong for fish.
Type of Aquarium Air Pumps
The are three type of air pumps in general. They are:
- Battery Powered
- Battery Backup
Plug-In Air Pump
This is going to be the more common air pump you come across. They plug into your outlet and run all day. Super simple and for the most part very reliable. They do not have an on and off switch and are meant to run 24-7. You can if you want control their operation of you have a controllable power outlet.
Battery Powered Air Pump
These air pumps operate off batteries. They are smaller air pumps and come in handy in the event of a power outage. The batteries tend to last a good while – usually around 8 hours. All battery powered air pumps are unfortunately very loud. It’s simply not their main design to be quiet. They are designed to be used in a pinch. They are not designed to be your primary air pump in your aquarium. I would recommend that you have a battery powered air pump on hand for emergencies. They will save your fish tank one day.
Battery Backup Air Pump
This air pump is a combination of the two previous types of air pumps. They plug into your outlet and have a bay to place backup batteries in the unit. When the power goes out, the battery backup will kick in keep your fish tank oxygenated. Lack of oxygen is one of the major reasons for a tank crash during a power outage. A high end unit will likely save your aquarium one day from a power outage. They are priceless units.
Tank Air Pumps – A Quick Comparison
There are many type of Air Pumps available today, but what is the best out there? The following air pumps have been reviewed with durability, function, and quiet operation in mind. There were many air pumps that did not make the cut. There were several that we cut from this list because we have field experience with these. The ones that I dropped are too loud, very expensive, or not very reliable. Below are the air pumps I would recommend.
In a hurry? I recommend Eheim Air Pumps!
The Best Aquarium Air Pump – The 7 Best (2021 Reviews)
Let’s dive deep and see why these made the list!
1. Eheim Air Pump – The Quietest Aquarium Air Pump
The Eheim Air Pumps are without a doubt the quietest aquarium air pumps you can buy on the market today. They are powerful, quiet, and well made. Afterall, Eheim is well known for producing excellent aquarium equipment for the hobby. The other great thing about this air pump is the diffuser that it comes with is pretty good. This eliminates the guess work with having to buy an air stone. They also give you a check valve in the box. It is a well engineered and well thought out package.
It is a plug in only air pump. This means if you want an air pump with backup abilities you will need need to shop for another unit. You could also buy a separate battery powered air pump. The Ehiem pump is on the pricey side among the plug-in air pumps on the list.
- The quietest aquarium air pump on the list
- Eheim brand name
- Comes with a great diffuser and check valve
- Plug in option only
2. Fluval Q Series – Great Bang for the Buck Air Pump
The Fluval Q Series Air Pumps offer an entry level price with the brand name we love in Fluval. Fluval, as they have always done, backs up their equipment with a generous 2 year warranty on this air pump model. For a brand name air pump, it has a get price point and should definitely be a consideration over cheaper Chinese made units out there. It is a powerful unit with dual air outlets.
Due to the units power, it does give off more noise than I would like. The sound level is more equal to lesser brand names. This is disappointing for a Fluval branded air pump. But given they are designed for larger tank capacities, it may be worth looking at if noise isn’t a concern for you. The price point for a brand name air pump is great.
- Cheap for a brand name air pump
- Fluval brand name
- Surprisingly loud given the brand name
3. Tetra Whisper – Great All-Around Air Pump
The Tetra Whisper Air Pump is a staple in our industry. Tetra and their name brand Whisper has been what what they are known for. The air pump is their major item in the Whisper line up. The Tetra Whisper has a good balance of features. It is very cheap compared to the others on this list and it is quiet. It also doesn’t look that bad in your cabinet or hanging outside of your tank due to its unique shape. I guess you could say there is a bit of a cool feature with it’s not boxy look.
It is cheap and gets the job done. If you are looking for value, the Tetra Whisper is for you!
- Good balance of features
- Not as quiet as the premium brand models
4. Tetra Whisper AP – The Best Large Tank Air Pump
The Tetra AP Series Air Pumps are pumps designed for larger tanks.This is Tetra’s best product within the Aquarium trade. It is super quiet for how powerful it is. It is not as quiet as the Ehiem air pump. But, it is close and operates at much larger aquarium capacities — up to 300 gallons in fact. Even with it’s large operating capacity, it is still retails at a great price. To top it all off, Tetra backs this air pump with a limited lifetime guarantee. What isn’t there to like here?
The only grip I have with this air pump is it only comes with a single airline outlet for the AP 150 outlet. That is fixed with a proper Gang Valve.
- Quiet for a large air pump
- Value Priced
- Limited lifetime guarantee
- AP 150 only has one airline hose outlet
5. Cobalt Rescue – Great Air Pump With Back-up Capability
The Cobalt Aquatics Rescue Air Pumps is our first pump on the list with back-up capability. It comes with an internal battery that can power the air pump for 24 hours in the event of a power outage. Add to the fact that it can be plugged in, this unit afters a primary air pump with power outage backup. It has a good amount of power output and should suit a medium sized fish tank.
Given that it is a unit that offers a battery backup function, it is on the pricier size. It has also been reported as loud compared to some of the more quiet models that we will be looking at later. If noise isn’t that much of a concern for you and you want a power backup option, this unit would be a great pick for you.
- Backup capability with internal that lasts up to 24 hrs
- Powerful out of the box – will suit most aquariums
- Not as quiet as other models
- Louder than other models
6. Penn Plax Silent – A Quality Battery Powered Air Pump
The Penn Plex Silient Air B 11 is the perfect battery powered air pump. It has a good amount of power, being able to handle tanks up to 29 gallons. The unit is powered by 2 D batteries that should give you a life of about 6-8 hours. The auto-on feature is a nice bonus as you can plug this to your outlet and it will monitor if a power outage occurs. If a outage occurs, the battery powered unit will turn on.
This is great piece of mind if you go out of town or away from your aquarium and an outage occurs. I feel that every aquarium owner should have one of these units. They will save your livestock one day.
It is more expensive than other battery powered air pumps on the market. Yet, the generic and cheaper alternatives out there are not very reliable. This is a piece of equipment you pull out when your pet’s lives are in danger. I’d rather spend more for something I know that is going to work. Going for a cheap unit that may or may not work when it is most needed can be disastrous. This unit is not built for quiet. In fact, it is the loudest air pump on this list by far. But, that’s not it’s function. It exists to save your pets lives in the event of a power outage. This is an air pump you should buy today as part of your emergency planning.
- Battery Powered
- Good power – works for up to 29 gallons
- Auto On Feature
- More expensive then other battery powered air pumps
7. Deep Blue Professional Hurricane Category 5 – The Ultimate In Battery Powered Backup Air Pumps

Armed with a lead acid battery pack, this unit does not mess around with its battery backup capacity. It not only comes with a 4.0 Ah battery out of the box, it will also operate with 12 Ah. It is some great piece of mind to know you can work the unit with these larger batteries if needed. Note that if you use a 12 Ah battery you will not be able to house the battery in the unit. It is a powerful air pump that is designed for mid-size aquarium. With dual airline outlets, this unit can serve as your primary air pump as well as your backup. This has everything you want in a good air pump.
You get what you pay for with this unit. It is the most expensive air pump on the list and its larger size will produce more noise than the Eheim. If you have a mid-size tank and want to protect your investment out of the box, this is the unit to buy.
- Battery backup that will run for days not hours!
- Dual airline outlets
- Louder than others on the list
What Is the Best Aquarium Air Pump (Our Recommendation)
So what is the best aquarium air pump on the market? Well, we have many factors to consider with sound level, budget, and the size of the aquarium. I broke it the list of recommendations in several categories to help with your decision.
Quietest Air Pump – Eheim Air Pump
Without a doubt the Eheim Air Pump line is the quietest aquarium air pump you can purchase today. If noise level is your top priority, look no further
Best Large Aquarium Air Pump – Tetra Whisper A Series
The Tetra AP Series Air Pumps are the ideal choice for larger aquariums. They are the most powerful air pumps on the list and quiet for their output. With larger aquarium you tend to get more solid stands like oak cabinets. This means you can likely get by with a noisier air pump.
Budget Option Air Pump – Tetra Whisper
The Tetra Whisper Air Pump is easily the best budget option pump on this list. They are cheap, get the job done, and are not that noisy. If you are on a budget, you can’t go wrong with it.
For those of you with higher end budgets, the Deep Blue Professional Hurricane Category 5 Air Pump is an excellent choice. A large tank can have hundreds of dollars of fish. These fish who have lived for many years that are only a power outage away from getting wiped out. Protect yourself with the best if you have a large setup.
Aquarium Air Pump Accessories – Getting the Essentials
So we have got through all the best aquarium air pumps available to buy today. Before you go get your air pump, let’s talk about all the essential accessories. You will want to look into these before setting everything up. They are:
- Airline Tubing
- Air Check Valve
- Air Control Valve
- Airline Connector
- Gang Valve
These connect your air pump to your air stone, bubble, or sponge filter The tubing transfers the air flow to your fish tank. They are very cheap to obtain and just about any you purchase will be very reliable. I would recommend Penn Plax’s Airline Tubing or Lee’s brand if shopping locally. All you do is measure and cut to length and you are good to go.
Airline Check Valve
An Airline Check Valve is an accessory that will prevent your airline tubes from siphoning water out of your aquarium. This can occur in the event of a power outage or equipment failure. They are a must for any air pump application.
Air Control Valve
An Air Control Valve is an accessory that allows you to have more precise control over your Air Pump’s output. They work by turning the valve to reduce or increase the air flow. All all control valves are created equal. I prefer the one pictured above by Fluval.
Air Stones and Bubblers
An air stone or aquarium bubbler helps better distribute the oygen into your aquarium. Without either, the airline connected to your air pump will generate big bubbles. These large bubbles can be loud and disruptive to your water line. In a freshwater fish tank, we prefer a smooth distribution of bubbles.
The finer the better as this provides more rich oxygen into the aquarium. Air stones are the standard that most of us in the hobby are used to and provide fine bubbles. Bubblers are more expensive than air stones and take it a step up producing a fine mist of bubbles. Air stones are cheap and get the job done, but if you want the best, go with a bubbler.
Airline Connectors are plastic pieces that allow you to split your airline in two or to connect your airline at 90 degree angles. They come in handy when you have a lot of airline that you need to work with. Airline tubes can get bent reducing the output of your pump. The connectors will create a good directional change for you preventing the issue.
A gang valve is an air pump accessory that will split your airline output into multiple lines. It also has an added benefit of being able to control the air flow of each line. It’s a combination of an air control valve and airline connectors. I would recommend Penn Plax’s Gang Valve if you are looking to get one.
How to Reduce the Noise From Your Aquarium Air Pump
A common question I get from readers is how do I reduce the noise from my air pump. Of all the features and models I listed on this best of post, the primary concern with an air pump is noise. The unfortunately truth is that all air pumps make sound. There are two things we can work on here when it comes to noise:
- Quality of sound
- Reducing sound
The quality or the type of sound that your air pump produces is a major factor. A lower quality air pump will rattle and bump while the higher quality brands like Eheims will hum along. An air pump that hum along tend to not annoy people, even if they are louder than the ones that rattle.
Reducing the sound itself is the next thing we can work on. We can do the following to further reduce the noise produced by our air pump:
- Raise the depth of our airstones
- Moving the air pump to a different location
- Fill any unused airline outlets
Raise the Dept of Your Air stones
For smaller pumps, they will work harder the deeper your air stones are placed in the tank. You can solve this by moving the air stones up or consider purchasing a larger air pump that can operate at those depths without having to work hard.
Move Aquarium Air Pump To A Different Location
Air pump location is a very important factor. If they are leaning on something, they can create more vibrations that can create more noise. Even the surface it sits on could create a problem. If the surface is an issue, you can consider moving it or place the air pump on a Neoprene Mat.
If you have an Aquarium Cabinet with doors, placing the air pump inside the cabinet can muffle the noise. Keep in mind that many budget built aquarium cabinets are made of particle board. Particle board and an air pump are a bad combination. Consider a neoprene mat to migrate the noise if you are using such a cabinet. Oak cabinets fare a lot better at noise absorption.
Fill Any Unused Airline Outlets
Some of the air pumps we have featured in this post have multiple airline outlets. This is great for having the ability to use multiple airlines out of the box, but can also create a problem if you do not utilize them. Unused airline outlets will be noisy as the air pump will push air to these outlets even if unused. To reduce the noise, one way would be to plug in airline tubing to the unused outlet. It will generate less noise then if the outlet was left open.
Conclusion – Best Aquarium Air Pumps
We went through quiet a lot today. We learned about how air pumps work. What different models are available for purchase. We looked at accessories for our air pump. We then provided a few pro tips to make your pump as quiet as possible.
The fact of the matter is air pumps do generate noise. There is no way around that. But, we want to reduce that noise as much as possible. We want a quality air pump that produces a sound that will not annoy us. An air pump should produce a smooth sound versus a banging or clanging sound.
