How to Choose the Best Aquarium Filters

There are so many different kind of aquarium filters out there, you might be wondering which is the best kind for you. Well, you can stop wondering because we did our research and looked at some of the newest and best-selling filters to help you choose. Before we get into our aquarium filter review, let’s take a quick look at some of the features you need to consider when choosing the best aquarium filter for you.

Best Aquarium Filters

Capacity - The size of your tank determines how powerful a filter you’ll need. Obviously, a 100-gallon tank will need something a little more substantial than a 5-gallon tank. Getting the right size is key to getting clear water.

Best Aquarium Filters

Pump Output - For filters with a pump, this is the measure of how fast it filters the water. It should be roughly 3 times the tank capacity. Some filters don’t use these kind of pumps, though, and you’ll need a separate air filter instead.

How to Choose the Best Aquarium Filters

Accessories - No, we aren’t talking about decorations. We consider filter media to be the only accessories your filter needs. It’s a nice bonus if everything you need to get started - mechanical, chemical, and biological filter media - is included with your pump.

Best Aquarium Filters

Quiet - None of these filters are loud. Sure, some are louder than others, but they’re all relatively quiet. For filters that require an air pump, keep in mind that you’ll need to consider the noise it makes, too.

Best Aquarium Filters

Dimensions - Filters come in all shapes and sizes. Wide, short, narrow, tall. That’s good because you know what else comes in all shapes and sizes? Aquariums. Find one that suits the shape of the one you have.

Product Intro Icon

Warranty - Warranties are always important. Make sure you know what’s covered and what isn’t. Some filters have more moving parts than others and are therefore more likely to break. A good warranty can help offset that.
