Types of Pool Filters

Sand Filters

One of the most popular types of pool filters is the sand filter, which uses a bed of sand to separate debris from the water. Sand filters work by directing water through a distribution system and into the top of the sand bed. As the water passes through the sand, small particles and debris get trapped, while the clean water exits through the bottom and returns to the pool. Sand filters have several advantages, including their affordability and low maintenance requirements. They are also highly effective at removing small particles and debris, making them ideal for pools located in areas with high levels of environmental debris. However, one of the main disadvantages of sand filters is that they require backwashing to clean the sand bed, which can be a time-consuming and wasteful process. Additionally, sand filters may not be as effective at removing larger particles, which can lead to clogs and reduced filtration efficiency. Overall, sand filters are a popular and effective choice for many pool owners, but it’s important to carefully consider your specific needs and maintenance preferences before making a decision.

Cartridge Filters

Cartridge filters are a popular type of pool filter that utilizes a replaceable filter cartridge to capture debris and prevent it from re-entering the pool water. These filters work by passing water through a pleated, corrugated, or spun-bonded filter cartridge that traps dirt, debris, and other contaminants. The cartridge itself is made of a porous material that allows water to pass through but captures the dirt and debris. One of the main advantages of cartridge filters is that they require very little maintenance compared to sand filters and DE filters. Additionally, they provide excellent filtration, easily trapping particles as small as 10 microns. However, they do require regular cleaning and replacement of the filter cartridge to ensure proper performance. Cartridge filters are an excellent choice for pools with relatively low levels of debris and for those who want a low-maintenance filtration system that provides excellent water clarity.

DE Filters

DE filters, also known as Diatomaceous Earth filters, are considered to be the most efficient type of pool filter. They work by using a porous powder made from fossilized diatoms to capture debris and dirt particles. As water passes through the filter, the debris is trapped by the powder, allowing only clean water to pass through. DE filters are able to capture particles as small as 2-3 microns, making them more effective than sand or cartridge filters.

One of the advantages of DE filters is their ability to maintain high filtration rates for longer periods of time compared to sand or cartridge filters. They also require less maintenance, as the DE powder can be easily refreshed with a recharge or backwash. Since DE filters require a lower pressure to operate, they also promote better water circulation, leading to better overall pool health.

However, there are also some disadvantages to consider when choosing a DE filter. They are typically the most expensive type of pool filter, and their installation and maintenance can be more complex than other types. Additionally, the use of DE powder can create a mess during installation and recharge, and proper disposal of used DE powder is necessary to avoid environmental damage.

Overall, DE filters are a great choice for pool owners who value efficiency and higher filtration levels. Their ability to capture even the smallest particles in water makes for cleaner and safer pool water. However, their higher cost and maintenance requirements may not be practical for every pool owner.

When the water pressure in the pool drops, it can signal that it’s time to replace the pool filter. There are steps that pool owners can take to identify the cause of low water pressure, including checking the pool filter for dirt and debris. They can also check the pump to see if it’s working correctly.

Replacing a pool filter can be a daunting task for new pool owners, but it is a simple process that can be done in a few steps. First, the new filter should be chosen based on the size of the pool and the filtration needs. Next, the pool filter should be shut off, and the pool pump should be disconnected from the filter. The old filter can then be removed and replaced with the new one. The connections should be checked to ensure they are tight and leak-free.

Regular maintenance of the pool filter is essential to ensure that it runs efficiently and provides clear and healthy water. Filters should be regularly checked for debris, and they should be cleaned or replaced as needed. A well-maintained filter can significantly reduce the risk of low water pressure and other pool-related issues.

Dirty Filter

One of the reasons why pool water turns cloudy is due to a dirty filter. Over time, pool filters become clogged with debris and dirt, causing the filter to lose its effectiveness in removing impurities from the water. To ensure that the pool filter is working correctly, it’s essential to carry out regular inspections. Visually inspecting the filter can help identify if it’s clogged with dirt and debris. Start by turning off the pool pump and opening the filter housing.

Next, take a closer look at the filter media, ensuring that it’s free of dirt and debris. Rinse the media with a hose to remove any accumulated debris. Lastly, check the pressure gauge; it should be within the appropriate operating range. If the pressure is low, it’s an indicator that the filter needs cleaning or replacing. In sum, inspecting the filter regularly can save pool owners from having to deal with cloudy water and low water pressure.

When to Replace a Pool Filter


The age of a pool filter can significantly affect its performance. Over time, filters can become clogged with dirt, debris, and other contaminants, leading to reduced water flow and increased pressure within the system. As filters age, they also become less effective at removing smaller particles from the water, leading to decreased water quality and potentially harmful conditions for swimmers. Furthermore, as filters age, they may begin to break down and deteriorate, leading to cracks, leaks, or even failure of the entire system. It is essential to monitor the age of your pool filter and replace it when necessary to maintain the highest level of water quality and performance. Regularly replacing pool filters can help prevent unnecessary repairs and prolong the life of other pool equipment, ultimately saving you time and money in the long run.


The manner in which a pool filter is used significantly affects its performance and overall lifespan.
