As you can tell from its name, the Aqueon QuietFlow Power Filter is designed to generate as minimal noise as possible during operation. Even though it is a power filter, it comes with an internal pump that effectively dampens noise, allowing for almost silent operation.

I also love that the pump starts up automatically following a power interruption or clean-up, making your work a lot easier.

What to Consider When Looking for the Quietest Fish Tank Filters

Here’s the thing, the best quiet fish tank filter might not necessarily be the ideal choice for your aqua life simply because it is convenient for you. That is the harsh truth. The most important thing to consider is how effective the filter is at purifying your fish tank’s contents.

As such, it is crucial to understand the different types of aquarium filters, and how they work so you can determine whether the quiet is a good trade-off.

Types of Aquarium Filters

As mentioned, there are several types of fish tank filters, with each having its inherent advantages and disadvantages. Needless to say, the filter’s design plays a significant role in the amount of noise it generates during operation.

There are three main types of aquarium filters: internal filter, hang-on-back filter, and canister filter.

Internal Filter

Internal filters, also known as sponge filters, are the most basic aquarium filters. This unit requires only three parts to work: a sponge filter inside the aquarium, an air pump outside, and tubing connecting the two.

Internal filters are the poster child of mechanical filtration; the air pump forces air into the sponge filter, resulting in air bubbles that draw the tank’s water into the sponge. The sponge works as both a mechanical and biological filter media.

The benefits of using an internal filter include cost-effectiveness and reliability. Since they are so basic, making one yourself is ridiculously simple, as seen in this video.

However, they take up too much space inside the tank, making them unideal for smaller aquariums. Moreover, since they rarely utilize chemical filtration, they are not as thorough as you would want them to be.

Nevertheless, internal filters are reasonably quiet during operation.

Hang-On-Back Filter

Also known as power filters, hang-on-back (HOB) filters are arguably the most common type of aquarium filters today. As its name suggests, the HOB filter is designed to hang outside the tank, with an intake tube dipping into the aquarium’s waters.

Most HOB filters today utilize all three filtration techniques, i.e., mechanical, chemical, and biological, to purify the tank’s contents.

Since HOB filters use a motor to suck water into the filter box for purification, they tend to be rather loud. However, some manufacturers today are taking steps to reduce the noise generated by utilizing noise dampeners.

If you are looking for a happy medium between cost and effectiveness, HOB filters are arguably the best option for you.

Canister Filter

The canister filter is the Lamborghini of aquarium filters. This unit comes in the form of a lidded plastic cylinder that houses the filter media and a motor. The cylinder sits under the fish tank, with hoses connecting to the aquarium’s water.

The mechanism is simple: the motor draws water into the canister, the numerous levels of filter media perform their magic, and it is then returned to the tank.

Canister filters typically come with all types of bells and whistles to make filtration and maintenance a breeze. Most importantly, they are the quietest fish tank filters in the game today.

Their inherent design ensures that no sound is generated during operation since the filtration box is encased inside a pressurized chamber.

As you can imagine, these units are not cheap by any means. However, they are the sturdiest, most aesthetically pleasing, reliable, and quietest of all aquarium filters. Finally, and most importantly, canister filters can handle any tank size.


Which is the quietest aquarium filter?

Canister filters are your best bet when choosing a silent fish tank filter.

How can I make my fish tank filter quieter?

Adequate maintenance is key to ensuring a smooth and quiet filtration process. If the cartridge gets clogged, the motor will work harder to pull water into the filter, thus increasing the amount of noise generated.

Do fish mind the noise generated by filters?

As long as there’s nothing inherently wrong with your filter, your fish won’t mind the hum produced by most filters.

Final Thoughts

If the constant hum of your fish tank filter is a never-ending source of annoyance, you should consider switching to the Aqueon QuietFlow LED Power Filter. It features top-tier filtration tech and does not make a fuss during operation. Moreover, it comes with a lifetime warranty.

If you want the quietest filters money can buy, a good canister filter such as the AMOSIJOY is the safest pick. This is because it has been designed to be essentially noiseless.

I hope that this guide has been insightful in your search for the quietest aquarium filters.
