Best Above Ground Pool Filter Systems
Before we get into which pool filter systems was chosen as our best picks I want to mention that this was a much tougher than picking the best above ground pool or ladder. There are some great filter systems for above ground pools and the differences between them are minimal. I will give you the names of the others and explain these small differences, but first I want to elaborate more on the types of pool filter systems available, how they work and what the advantages are to each. It’s also important to note that above ground pools typical use a filter “system” which combines a matched filter and pool pump mounted to a based for easy set up and minimal plumbing. These filter systems also include all the fittings, hoses and clamps required for installation.

For you die-hard bargain shoppers or pool customizers out there, I mentioned somewhere on this site before that you should never use price as your only criteria when shopping for a specific pool item, and filter systems are a perfect example of what I mean. What you may think is a huge savings on a new filter system may turn out to be a total mistake, so a little knowledge will go along way here.
When bargain shopping it’s very important that you pay close attention to the details, because practically every filter system is available in many configurations that can greatly effect their price and usability right out of the box. For some people or pool builders these variations in product offerings are great news, but for the average pool owner this can be a pitfall. Here’s an example of the ways a same named filter system could be configured.
- Different power cords. Some are standard cord while others are twist-lock. They don’t plug into the same power outlet as the prongs on the cord are in different locations.
- Different size motors available on the same filter system. Most above ground filter system are available in .75hp, 1.0hp and 1.5hp
- Different grade pumps available on the same filter system. Dynamo pump , Matrix pump, Power Flo pump, Power Flo II pump, etc.
- Some systems come with or without the hose kit. No hose kit means no out of the box way to hook the filter system to the pool. You must create your own plumbing.
- Some systems come complete with everything mentioned above minus the actual filter element inside. That’s sold separately and can cost an additional $100-$200.
- Shipping cost. Make sure to factor in the total price of the system including shipping and handling. Often not advertised.
- How A Cartridge Filter Works – When the pump is running, water coming from the pool enters the filter tank and passes through the filter’s pleated cartridge element. As the water is forced through the cartridge, hair, dirt, bugs, algae and other debris are caught on the outside of the cartridge and clean filtered water passes through and is returned back to the swimming pool.
- Cleaning The Cartridge – Like all swimming pool filters, the cartridge filter needs cleaning on a regular basis. Doing so is a easy operation. First turn off the pump and release any pressure within the filter tank by opening up the air relief valve. Now remove the upper half or top of the filter tank and remove the filter cartridge for service. Once removed, spray off the exterior and between the pleats with a garden hose. Use a nozzle to create a blasting or pressure cleaning effect. This step should take only 5-10 minutes to perform a good rinsing. Once cleaning of the cartridge is complete, simply reinstall the filter cartridge and reassemble the filter tank. Once back together, you are good to go for another week or two.
- Cartridge Replacement – Time, cartridge size, bather load, hours of use, chemicals, suntan lotion and more will eventually take their toll on the filter cartridge. They become clogged and the fibers that make up the cartridge begin to break down and water can no longer pass through efficiently. The factors described above dictate the life of the filter, but as a general rule most cartridges last 2-3 years in North Florida.
- Cartridge Filter Pros & Cons – The cartridge filter is a simple design with few moving parts inside. This makes for a reliable long lasting pool filter. Cartridge filters often have a tall and slender design which makes them perfect for tighter spaces. Compared to sand filters, they offer a larger filtering area making them an attractive option for most any swimming pool owner. The micron rating is greater making the cartridge system more capable of filtering out much smaller particles in the pool water than the sand filter. This makes removing fine contaminants like algae much easier to do. This is especially important in hot southern climates like North Florida where water temperatures can easily reach 90°+. When water temperature are this warm algae grows very quickly is adequate chlorine levels aren’t maintained. The only downside compared to a sand filter in my book is the amount of work or time spent cleaning the system. I feel that the additional 10 minutes and the inconvenience of getting my feet wet are a small price to pay for much better system for most applications. A cartridge filter would definitely be the choice for my pool.
How A Sand Filter Works – In swimming pools, water is pumped into a large tank that is filled with #20 Silica sand. As the water enters the top, a diffuser sprays the water out evenly across the top of the sand bed, ensuring perfect distribution.This water settles down through the sand bed entrapping the debris and returns back to the swimming pool filtered.
As the amount of debris, hair, bugs, algae, oils and more increases, the sand starts to become clogged. This restriction is noticeable on the pressure gauge located on the filter tank. The increase in tank pressure indicates the the filter is in need of cleaning or back-washing. The back-washing process rinse the sand of impurities and allows the water to flow freely again. The ease of flow lowers the pressure within the tank and the process starts over again. Keep in mind that the more a sand filter plugs up, the finer the particulates that are captured so its ok to let the pressure climb some, and not backwash too frequently. Normal operating pressure varies by filter but typically it runs between 10-20 psi. When the pressure within the tank increases by about 10 psi or more, back-washing is needed. Allowing too much pressure to build in the tank can damage the pump and possibly the filter tank.
Cleaning The Sand Filter – To clean or back-wash a sand filter, cut the power to the pump and set the control valve to backwash, then turn the pump back on. The filter will now rinse the sand within the filter tank, sending dirty water out the back-wash port. This water can be directed away from lawns, flowers or gardens as it is chlorinated and may cause damage to plant life. This is done simply by using a backwash hose attached to the back-wash port. Continue to backwash for about two minutes or until the water runs clear through the sight glass if equipped. Shut the pump off again and return the control valve to filter mode.
Sand Filter Pros & Cons – Sand will filter down to about 20 microns. This is small and enough to capture most all impurities in your pool water but this isn’t good enough to make the filtering out of algae an easy take. I have seen the algae pass right through the sand tank and back into the pool water. This can be quite frustrating when trying to get a green pool clear again. Sand filters will also becomes clogged and cakes up over time due to the accumulation of oils, lotions, hair and other debris. Even with regimented maintenance the sand within the filter tank should be replaced every 3-5 years for best results. About the only advantage sand filters offer in Florida is they’re easier to clean than the cartridge filter.
