About this list of Best External Filters for 2024
External Filters are used as aquarium filtration systems which sit on the outside of the fish tank, either freestanding, hanging on the rim or placed out of view in a cabinet. They differ from internal aquarium filters in such that they do not take up any space in side your fish tank, freeing up room for extra aquascaping or a more realistic habitat.
Above are listed the top 5 best aquarium external filters for 2024, based on Real Aquatics 2023 sales and reliability data from Real Aquatics outlets on eBay, Amazon and official websites.
The list above consists of both external and hang-on filters only, and does not include variations such as internal filters and sponge filters - these are featured in separate lists.
