Buying Guide: Best Above Ground Pool Filters

When in search of the best above ground pool filter for you, there are a few features that you’ll want to keep in mind. Let’s dive in and find out what you should pay attention to! 


One of the first features that you should think about is the weight. If your filter for the above ground pool is heavy, it can be hard to move, manipulate, and transport. While some people don’t have to move their pump often, some do – depending on the pump itself and whether it can handle the outdoor conditions. If you have a big pool and require a big pump to keep your water circulating, and in the right condition – go ahead. If you need a pump for a small pool and you don’t plan on using it that often, then consider getting a pump that won’t cause more inconvenience than the enjoyment. 


Materials that make up the filter pump are the piece of the equation that can’t be overlooked. One of the main features that materials that make up the pump should be is corrosion-free. The pump will inevitably come in contact with the water, and if you want it to last very long, it should be corrosion-free. Anything else just isn’t going to cut it. Look for the pumps that have a protective coating and that are made of polymers, and then you might find the best pool filter.


Gallons per hour is a unit that explains how much water a pump can move during an hour or a minute. It will tell you a lot about its power and possibilities. Of course, you want this power to go as high as it can. To calculate which GPM your pool requires, you can turn to this Pool Gallon Calculator. 

The size of a pool

Before you start looking for the filter pump, you’ll have to know the exact dimensions of your pool. You can then use the calculator to help you determine how many GPHs your ump should have and how much power it should be able to generate. When you’ve determined those variables, make sure your pump is suitable for the pool you have. 

Frequently Asked Questions (FAQ)

1) Question: Which type of pool filter is best?


• Sand filters

There are several types of pool filters. One that’s most commonly used is the sand filter. The filters are filled with sand and they collect the small particles and the dust that appear in the water. There is a barometer at the top of the filter where you can see the pressure inside. When there is a lot of dirt, the pressure rises so you know that you need to backwash the filter as soon as possible. This requires a multiport valve and it can have many different consequences as a result. They are not very effective, so why are we using them? Because they are affordable, easy to use, the sand doesn’t need to be replaced often – in fact, it should be replaced every 5 years, and last, but not least, they don’t require a lot of maintenance.

• Cartridge filters

Cartridge filters are good at filtering the small particles between 10 and 15 microns. These kinds of filters are the easiest to clean and maintain. The only thing you need to do is to take the garden hose and to wash it off. It’s very easy to install, convenient when it comes to filter-changing, it’s also easy to clean but it’s a great place for the algae to make it a home, so you’ll have to clog the cartridge.

• D.E. Filters

D.E. Filters, or Diatomaceous Earth filters are the most effective when it comes to filtering the particles out of your pool. It works on a principle that’s similar to the sand filters, but instead of the sand, it uses the fossilized remains of diatoms and filters out the particles that are between 2 to 5 microns big. Its maintenance costs are a little higher, and it takes more time and energy to disassemble the filter grids. Furthermore, it also gets cleaned by backwashing, which can cause additional complications.

As you can see, the answer to this question isn’t simple. All of the filters are good in their way. The sand filter is the most convenient, but the D.E. Cleans the smallest particles. Cartridge filters are easiest to clean. The ones that have to backwash can affect the water itself, as well as pool draining.

2) Question: How to select the right pool filter for your pool?

Answer: As you can see from our buyer’s guide, and from the different types of filters we’ve talked about in the previous question, there are many features that you want to keep in mind when choosing the best above ground pool filter for you. Take into consideration your budget, for starters. How much money are you willing to spend? Is this a really important investment for you and you plan on using the pool and the pump every day? Do you need the better, stronger model? What does my new filter need, that the old one doesn’t have? Those are just some of the questions that you should ask yourself to decide which filter is right for your pool.

What you must pay attention to, and what isn’t optional, is that you must select the filter that matches the size of your pool and that’s compatible with it. Before deciding to purchase your filter pump, make sure you check the hoses, connection points, and see if they’re compatible. Make sure you also maintenance costs into consideration, as they’ll be part of your monthly budget. Sand Filter is the one that’s most convenient if you want low monthly fees.

3) Question: How does the above ground pool filter work?

Answer: That depends on the type of filter that you buy. As we’ve explained earlier, there are different types of filters. All of them use a certain mechanism to trap unwanted particles. The water goes through the sand or fossilized remains that are in a canister, and the particles remain trapped inside, while the rest of the water goes out into the pool with the help of a pump. The particles get stuck in between, and thus, the efficiency of the filter increases. When it becomes overwhelming, the barometer on the top of the filter will show high pressure and you’ll know that it’s time to clean the filter.

Many variables need to be taken into consideration, but once you make the right decision – you can enjoy crystal clear water all day long.
