How We Chose the Best Above-Ground Pool Filters

We considered the type of filter—cartridge or sand—as that distinction affects the ease and level of maintenance you’ll need to perform to keep your filter running smoothly. All of our selections are combined pump-and-filter units, so there’s no need to worry about filter compatibility with an existing pump.

In addition, the gallons per hour (GPH) flow rate and system flow rate are critical components of choosing the best filter for your above-ground pool: too low a rate and your pool will be cloudy, or too high and you’re wasting money on electricity. Finally, we examined the ease of installation and use, handy features such as skimmer and timers, strainer baskets, and any extra components you might need to purchase separately.

Our Top Picks

We used the above considerations to narrow down the field of pool filters to some of the best models on the market. These filters include light-duty models for above-ground pools under 10,000 gallons and larger models for pools up to 57,000 gallons.

What to Consider When Choosing an Above- Ground Pool Filter

Understanding the type and size suitable for a specific pool and pump is essential to selecting the right filter for an above-ground pool. To help with your search, keep reading to learn more about these factors and other vital characteristics of above-ground pool filters.


Above-ground pool filters can use three different types of media to remove particles from the water: DE, cartridge, or sand.

  • DE filters are the most effective. They consist of diatomaceous earth, which is fossilized remains of microscopic organisms and skeletons from tiny animals. DE is a powder that coats the grids inside the filter. As water passes through the filter, the DE removes particles as small as 2 microns, which include algae, dirt, and some, but not all, bacteria. DE is one of the more costly media, as it must be changed about once a month and replaced with new DE to the tune of 1 pound for every 10 square feet of filter surface area.
  • Cartridge filters aren’t as effective as DE filters but still perform well. They use a standard filter cartridge that fits inside the filter. As water passes through the filter, it removes contaminants as small as 10 to 15 microns, which is tiny but still visible to the human eye. This includes dirt and tiny insects but not oils, bacteria, or viruses. Cartridge filters aren’t as effective as DE but are popular because they are easy to maintain. Whereas DE requires you to backwash the system once a month, cartridges can simply be removed and replaced about once every 2 weeks.
  • Sand filters are among the most popular options because they work well and are inexpensive. Sand filter systems have large tanks that hold sand. As water passes through, the sand removes contaminants as small as 20 microns. Like DE, sand filters require backwashing. However, they don’t need a continuous new supply of sand, as the sand can last about 5 years before needing to be replaced.

Pump Compatibility

For the filter to work correctly with an above-ground pool, it must be compatible with the pump to ensure there is the right amount of flow and pressure to send water through the filter. If the filter is too large for the pool pump, the pump won’t produce enough pressure to push water through the filter adequately. With too small a filter, the pump can overload the filter, hurting its performance and even damaging it.

Most manufacturers rate their swimming pool filters by flow rate, which is the amount of water they can filter in an hour. Pool pumps also have a flow rate, which is directly related to the horsepower of the motor. A pump and filter should operate no more than 8 hours each day to avoid straining the pump and filter and running up the electric bill. They should be able to turn over all the water in a swimming pool once during that period.

  • A pump with 1 horsepower produces a flow rate of about 3,000 GPH, while a 1.5-horsepower pump has a flow rate of about 4,000 GPH.
  • A pump between 0.75 and 1.5 horsepower is typically enough to handle any inground pool.
  • A 0.75-horsepower pump, which can move about 1,500 GPH, is adequate for small- to medium-size inground pools of under 15,000 gallons.
  • A 1.5-horsepower pump is suitable for larger pools of up to 60,000 gallons.

Some filters and pumps are conveniently sold as a single unit, eliminating the need to determine compatibility.

Additional Features

Above-ground pool filters include features that make them easier to use. Some higher-end models have pressure gauges, which allow you to monitor the pressure of the pump and filtration system. The pressure inside the filter is a good indicator of how well the system is drawing water and helps to determine if the filter is full and needs to be backwashed.

Using the filter’s drain port, sand and DE filters must be periodically backwashed to clear out the debris they’ve collected from the swimming pool. By attaching a hose to these drain ports, you can direct the waste to an appropriate drainage area when backwashing the filter.

Some filters have removable skimmer baskets that help collect and remove large debris such as leaves and twigs.

Ease of Use

Above-ground pool filters vary in their ease of use. Sand and DE filters are more complex, requiring you to adjust the filter to different settings to backwash, rinse, and even winterize the filter. They also require you to add sand or DE to the system periodically.

Cartridge-based filters are easy to use. Most cartridge filters consist of a combined pump and filter. When the filter is full, you simply turn off the pump, open the top of the filter, replace the cartridge with a new one, close the lid, and turn the pump on. They require no backwashing and typically have a single switch that turns the pump on and off.

Higher-end models of all three types of filters may have programmable timers that automatically cycle the pump and filter on and off, eliminating the need to turn the pump on and off manually.


Unlike inground pool filters, which are more complicated to install and often require professional installation, most above-ground filter installations are simple. Many models feature filters integrated with pumps, eliminating the need to make connections between the two pieces.

Installation typically involves connecting tubing from the pump to the pool, which draws water into the filter and an outflow that sends the water back into the pool. The inflow connection is typically on the wall near the bottom of the pool, while the outflow is usually on the wall near the surface of the pool water.

DE and sand models are usually more complicated, requiring connections between the pump and filter as well as the application of the sand and DE media. These filters generally take about an hour to set up. In contrast, setting up a simple cartridge filter system can take 10 minutes or less.

Cleaner Type

While pool filter systems do an excellent job of removing contaminants and impurities floating in the water, they can’t remove muck sticking to the walls or floor. Pool cleaners that attach to the pool filter perform this duty. Pool cleaners consist of three types: robotic, pressure side, and suction side. Suction-side pool cleaners are suitable for smaller pools with less powerful pumps, while robotic and pressure-side cleaners are ideal for pools with larger pumps and filters.

  • Robotic pool cleaners are the most advanced of these options. These pumps move around the pool automatically, crawling along floors and climbing walls, removing debris and dirt as they go. Some are so sophisticated they can “see” the pool’s surfaces and dimensions, ensuring they don’t miss a spot. Robotic vacuums typically run off of rechargeable batteries.
  • Pressure-side cleaners, per their name, attach to the pressure side of a pump. The pumped water propels them throughout the pool, allowing them to collect debris in an attached filter bag. While these models are cheaper than robotic cleaners, they sometimes require a booster pump to have enough power to operate, which can add to their cost.
  • Suction-side cleaners are the most affordable of the three options. These vacuums attach to the suction side of the pump, using that force to draw water and debris into the filter, which catches the dirt and sends the water back into the pool. This type of cleaner will wander randomly around a pool or can be operated manually. While suction-side cleaners are the most affordable pool cleaner, they do put more strain on the pool filter.


If you’re wondering how large a filter you need for your pool or how to install and operate your new above-ground pool filter, then read on for answers to some of the most commonly asked questions about these pool accessories.

Q. What size filter do I need for my above-ground pool?

The filter size depends on how many gallons of water the pool holds. Generally, a pool filter should be able to treat the entire contents of the pool in 8 hours. A filter capable of treating 750 GPH is suitable for pools with 6,000 gallons of capacity, whereas a pool filter capable of treating 7,000 GPH is suitable for a pool with up to 56,000 gallons of water.

Q. Is a sand filter better than a cartridge filter?

It depends on the application. A sand filter is more efficient at removing contaminants from a pool; however, it does require more maintenance. You must backwash a sand filter to rinse out impurities periodically, whereas a cartridge filter system uses disposable cartridges that can be replaced in a few minutes. With this in mind, most cartridge filter systems are well suited for smaller pools of 10,000 gallons or less, including those that aren’t used year-round. Sand filtration systems are ideal for larger permanent above-ground pools.

Q. How often should I run the filter on an above-ground pool?

The filter on an above-ground pool should be run daily when used regularly. It should be run long enough to filter the entire pool’s contents. The size of the pool, filter, and the power of the pump will obviously have an impact, but for most people, this will mean running the filter for 6 to 8 hours a day. Many experts say that the filter doesn’t have to be run consecutively. In other words, it could be run for 4 hours in the morning and 4 hours in the evening. This schedule may make it possible to benefit from lower electricity rates by running the filter at off-peak times.

Q. Do I leave the above-ground pool filter on all the time?

No. Leaving an above-ground pool filter on all the time will wear out the filter and pump, and it isn’t necessary to clean the water. The filter should run long enough to turn the pool water over once a day, a process that should not take more than 8 hours.

Q. How often should you change an above-ground filter?

A number of things will impact how often you should change an above-ground filter, including the type of filter medium or cartridge, frequency of use, product quality, and how well it is maintained. A key issue is always following manufacturers’ recommendations to maximize the filter’s working life. Generally speaking, life expectancy is likely to be 5 years or more, though this could be as low as 3 years in areas where lots of debris gets into the pool. A drop in pool water quality indicates the filter is past its best.

Q. How do I change my pool filter?

Changing a pool filter involves the following steps:

  • Begin by assembling the pool filter according to the manufacturer’s instructions.
  • Make sure the pump is turned off and unplugged.
  • Attach a hose that runs from the filter’s pump port to the discharge side of the pump.
  • Next, attach the filter’s return port to a hose that connects to the side of the pool.
  • If you have a sand or DE filter that requires backwashing, then connect a hose to a waste port that extends to a drainage area.
  • Turn the pump on to check for leaks and to make sure the system has the appropriate pressure.
