Are you planning on building your first above-ground swimming pool? Yes? Then you might be in search of an above ground pool filter suited for your brand new pool.

You might be currently researching what the best pool filter for an above-ground pool is. And with lots of available options, you may be overwhelmed.

But here we are to the rescue! This article will teach you the importance of having a pool filter system, selecting the right filter, and the best available options in the market.

Why Pool Filters Are Important For Above Ground Pools

Pool filters are essential to keep a swimming pool clean. It is a basic part of the pool filtration system along with the pump, pipes, and valves.

Above Ground Pool Filter

To understand why it’s essential, we need to know first how the pool filtration system works.  As the water in your pool circulates into the filtration system through the force applied by the pump. And as the water circulates, the filter removes dirt, debris, and other particles that contaminate the water. This continuous filtration process keeps the pool water clean and clear. [1]

Even though most above-ground pools are small, having a pool filter is still essential unless you want to replace the water after every use, which is quite wasteful and costly. 

Quoting Patrick Ness, an American writer, “A man without a filter, is chaos walking.” True enough, installing a pool without filters allows contaminants in the pool that can create health chaos and problems in the family. 

Now that we’ve established its importance let’s now move on to knowing the factors that constitute the best above-ground pool filter.

How To Select The Best Filter For An Above Ground Pool

Frankly speaking, there is no absolute best above-ground pool filter. However, there is a pool filter best suited for your needs. There are four steps that we’ll talk about that you’ll need to consider in order to buy the best pool filter suited for your above-ground pool. 

Compute The Pool Size

The first step to selecting the best-suited above ground pool filter for your pool is to compute your pool size. It’s essential to understand the volume of your pool to ensure you get an above ground pool filter that can efficiently handle the water capacity. When we discuss pool size in this context, we’re not referring to the perimeter measurements or the depth of the pool, but rather the total volume of the pool.

Typically, since above-ground pools come pre-made and only require assembly, the pool volume is mentioned in the product specification. This makes it easier for homeowners to choose an appropriate above ground pool filter. However, if you misplaced the pool brochure or can’t locate the specifications online, you’ll need to determine the volume manually.

To accurately compute the pool volume using manual measurements, measure the perimeter of the pool and multiply it by its depth. Once you have the volume, it’s crucial to convert this measurement into gallons to determine the right above ground pool filter capacity. Modern smartphones often feature calculators with conversion tools to assist with this. If your device doesn’t have this feature, use the conversion multipliers: 7.48 for volume in cubic feet and 264.172 for volume in cubic meters. This will give you a clear idea of what size of above ground pool filter you should be considering.

Choose The Type Of Filter To Use

There are three types of filters that you can use for an above-ground pool. These types of filters have their own pros and cons, which we’ll be talking about briefly. Take a moment to consider and compare each one which type will suit your needs best.

Sand Pool Filters

These filters are the cost-effective options out of the three available options. It uses sand as its filter medium, but you can replace it with alternative filter media such as glass and zeolite.

Although sand filters can only filter up to 20 microns, which removes most dirt and debris, you can pair it with a chemical treatment to effectively make the water clean.

Cartridge Pool Filters

This type of filter uses fabric-like material to remove dirt, debris, and particles in the pool water. As the name implies, cartridge filters have cylindrical cartridges in which the filter media is wrapped around.

A cartridge pool filter can remove particles up to 10 microns, much better than a sand filter, but it’s more expensive. So if you’re on a tight budget, then this might not be for you.

Diatomaceous Earth (DE) Pool Filters

This type of pool filter uses diatomaceous earth powder, fossil remains of aquatic diatoms, as its filter media. The powder is contained in cartridges or septums inside the filter tanks.

A DE filter is the most effective pool filter since it can remove particles up to 1 micron. It is also the most expensive out of the three options. So if you’re looking for a budget-friendly and nature-friendly filter, then this might not be for you.

Learn here about the importance of cleaning your pool’s filter as well as the proper procedures to follow.

Check For The Turnover Rate Of The Filters

After computing the pool volume and selecting the pool filter type, the next thing we have to consider is the turnover rate of filters. 

In the pool industry, the turnover rate of filter systems refers to the amount of time a volume of water (equivalent to the total pool water of your pool) can make one pass filter in a certain time period. 

If you try looking at a pool filter brochure, you can usually see that it has three to four turnover capacity rates with a unit of gallons per hour. The gallons per hour rating indicates how much pool water volume, in gallons, it can filter for every set number of hours.

For example, if we look at this Pentair brochure for their Clean and Clear cartridge pool filter. [2] On their CCP240 filter, you’ll notice that there are three turnover capacities indicated: 43,200 gallons per 8 hours, 54,000 gallons per 10 hours, and 64,800 per 12 hours. What this means is that it can filter 43,200 gallons of pool per 8 hours.

The Dilution Effect

You might wonder why the specifications have this weird hourly rating of 6, 8, 10, and 12 instead of the usual 25 hours. The reason? Dilution effect. 

The natural dilution effect states that although by computation, the amount of pool water that passed through the filter is equal to the total pool volume, it does not guarantee that all contaminants have been filtered. This is because the newly filtered water mixes with the unfiltered pool water.

That is why it is recommended for a swimming pool to make four or more complete pass-throughs to ensure maximum filtration. And this diluting effect is the reason why they use an hourly rating instead of using a rating per day. [3]

So let’s say that you have a 15,000-gallon pool. You’ll need to find a pool filter that can filter that amount in six hours. But you still need to consider if you want to operate the filter system for 24 hours. If not, then you’ll need to adjust the selected pool filter accordingly. But remember that it is still your choice if you want to follow the recommended number of turnovers per day. 

Ensure That The Pump And Filter Matches

A pool filter alone is not enough. You’ll also need the right pool pump to induce water circulation in the system. Selecting the right pump will ensure two things: high filter efficiency and high power efficiency. 

To know the best-suited pump, take a look at the product specification of your filter. You’ll find the gallons per minute (GPM) rating that it needs. 

Let’s take a look again at the previously mentioned Pentair filter. Notice that the flow rate needed is 90 GPM for the CCP240. So you’ll need to find a pump with the same GPM rating.[2]

Manufacturers make this pool pump selection process easy by offering filter system bundles that include filters and pumps together. So you can skip this step by buying these bundles. Again, the choice is up to you.

The Role of Filters and Pumps

Maintaining a pristine pool isn’t just about water. It’s about the systems behind it.

The ground pool pump is like the heart of your pool, circulating water and preventing stagnation. As it pumps, it pushes water through filters that ensure clean water returns by trapping debris. Tailoring your equipment is crucial; a smaller pool needs a smaller filter, while larger pools demand bigger ones.

Among popular filters is the Ground Pool Sand Filter Pump, which uses sand to trap impurities. Then there’s the Ground Pool Filter Systems, specifically the D.E. filters. They provide exceptional clarity, filtering to 5 microns, but might lose pressure faster and need more upkeep than sand or cartridge systems.

Lastly, investing in top-notch above ground pool filter replacement filters helps keep your system optimal and the water clear. In short, choosing the right equipment is vital for both clarity and safety.

The Best Above Ground Pool Filters In The Market

Now that we’re done with understanding how to select the best-suited filter for you let’s take a look at the best above-ground filters when it comes to cost, reliability, and features. While looking through the pool filter selection, try to compare and see what best fits your needs and budget.

How do I choose the right filter for my above-ground pool?

Consider factors such as pool size, maintenance requirements, budget, and personal preference for filter efficiency.

Can a filter keep my above-ground pool free from algae and bacteria?

Filters help remove debris and small particles but should be used in conjunction with proper chemical balance and sanitation to control algae and bacteria.

What is the maintenance difference between a sand filter and a cartridge filter?

Sand filters require backwashing and occasional sand replacement, while cartridge filters need regular cleaning and periodic replacement.

What size filter do I need for my pool?

The size depends on your pool’s volume of water. Generally, a filter should be capable of cleaning the entire volume of pool water in about 8 hours.

Is a DE filter better than a sand filter?

DE filters can trap smaller particles than sand filters, offering superior filtration, but they are also more expensive and require more maintenance.


In summary, it’s important to have an above ground pool filter even if you only have a small above-ground pool. Filtering ensures that above ground pools remain clean and clear.

When buying an above ground pool filter, there is no such thing as the ultimate or the best above ground pool filters. Selecting the best one means the right one for your pool. That is why you need to consider many factors such as pool size, filter type, turnover rate, and the pool pump capacity.

There are many great pool filters to choose from in the market. You can try choosing from great brands such as Hayward, Pentair, Doheny, RayPak, and WaterWay.
