12 Best Quiet Fish Tank Filter Reviews – 2020 Guide

Looking after a fish can be more work than you think, especially when it comes to ensuring their tank is equipped with everything they need to survive. Not only do you need to ensure they have the right tank, the right substrate and the right food, you also need to ensure you purchase the right aquarium air pump and the right filter so their water stays clean and non-toxic.

Fish tank filters can be known to make a lot of noise and this, therefore, limits where you can keep your fish. If you’re trying to concentrate in your office or trying to sleep in your bedroom, a noisy filter is going to distract you or keep you awake, so you might have to place your fish tank in another room.

Fortunately, there are fish tank filters on the market that are designed to operate quietly. This gives you the freedom to keep your fish wherever you want, without the worry of disturbance. In our buying guide below we explore how fish tank filters work, the types of filters available and what you should be looking for in the best quiet fish tank filter. We’ve even included some of our top picks out there, so if you want to learn more, keep reading on.


How Does A Fish Tank Filter Work?

An aquarium filter uses three different types of filtration systems to ensure that your fish’s home is clean and safe for them to live in. These are biological filtration, chemical filtration and mechanical filtration. Some filters use all of these types of filtration, while others only use one.

Biological Filtration

Biological filtration helps to remove any waste from your fish tank. Your fish is constantly producing waste and over time this will build up in the tank and cloud the water. Biological filtration usually works by converting your fish’s waste into a substance that is less toxic for your fish.

Mechanical Filtration

Mechanical filtration, also known as physical filtration, works by removing any particles from the water. A mechanical filter strains the water and catches any of these particles before they can dirty the water.

Chemical Filtration

Chemical filtration helps to remove harmful substances and impurities in the water that can harm or even kill your fish. Chemical filtration is usually done by activated filter carbon that is found in most filters and helps to remove chemicals.


Types of Fish Tank Filters

There are a few different types of fish tank filters out there available to you. It will be up to you to decide which one is going to be best for your tank.

Canister Filter

A canister filter is great for any tank of 40 gallons in capacity. They are great for mechanical, biological and chemical filtration because they are much larger than other filters. These filters have both a siphon tube and a flexible pipe that go from the filter to the tank. They are particularly good for cichlid, planted or saltwater fish tanks.

Sponge Filter

A sponge filter, also known as an air driven filter, is the most basic filter on the market and don’t do much when it comes to biological, mechanical and chemical filtration. However, they are great for breeding tanks, hospital tanks or tanks with small fish. The sponge filter is run by an air pump where the water is pulled through the sponge material and catches any debris.

Under-Gravel Filter

An under-gravel filter is a filter that you place under your gravel or substrate. They work by pulling water up through uplift tubes. This filter offers both biological and mechanical filtration, but chemical filtration does not happen with this filter.

Power Filter

A power filter, also known as a hang-on back filter, is probably the most common filter out there. These offer chemical, biological and mechanical filtration and hang on the back of your fish tank. These filters work by sending the water through a suction tube that is inside the aquarium and pushing the water through a filter pad. The filter pad often has activated carbon in it to help remove any harmful toxins.

Internal Filter

An internal filter is a compact filter and therefore great for small tanks or nano tanks under 20 gallons. They are stuck to the inside of tanks using suction cups. You get biological, mechanical and chemical filtration from an internal filter.

Wet/Dry Filter

A wet-dry filter is one of the most uncommon filters but are normally used by experienced tank owners. They are also usually used for saltwater tanks. These filters provide great biological filtration but do not provide good mechanical filtration as the water is not as restricted as it is with other types of filters.


Things To Look For In A Quiet Fish Tank Filter

Once you have decided which type of filter is going to be right for you, you’ll want to make sure it is quiet! Take a look at the features we think you should be looking out for in your quiet filter.

Noise Level

First and foremost, you’ll want to ensure your fish tank operates quietly. Fish tank filters are known to make some noise, especially a humming or buzzing noise. Fortunately, quiet filters are becoming more common these days, but you must be aware you may not find a filter that is 100% silent. The filters in our list are some of the quietest out there on the market, so take a look.

Size of Tank

Fish tanks can come in many different sizes from as small as 3 or 5 gallon fish tanks to very large, meaning fish tank filters also come in many different sizes. You’ll want to get one that is the right size for your tank so it does it’s job properly and doesn’t harm your fish. This will also mean it doesn’t make any unnecessary noise.


A filter is only going to get noisier the longer is goes without maintenance. Therefore, maintaining your fish tank filter and cleaning it accordingly is very important. If your fish tank filter is difficult to assemble or has lots of fiddly parts, then you’re going to be less inclined to service it and check it is working properly. Ensure it is easy to maintain before buying.


Fish tank filters can come at a range of different prices. You should be able to find one that fits within your budget and is of good quality. The more expensive, the better quality the filter is likely to be. This can help prevent rattling or excess noise due to poor manufacturing. However, there are many good filters out there at a lower price, too.
