Which Pool Filter Should I Use For A Residential Pool?

1. Sand Filters

Pool sand filters have long been a popular choice among residential pool owners due to their reliability and ease of maintenance. These filters catch and remove pollutants from pool water by using a bed of finely graded sand. A pool sand filter functions by allowing water to flow through the sand and trapping particles in the sand grains.

Advantages of Sand Filters

Sand filters have a big advantage in that they require less maintenance. Backwashing is a simple operation that reverses the flow of water to drain away trapped particles and is all that is required to clean the sand filter. Pool sand filters are thus an attractive option for pool owners who prefer a simple filtration system.

Limitations of Sand Filters

However, sand filters do have some limitations. They are less efficient at trapping finer particles than DE and cartridge filters and need occasional sand replacement (typically every five years). Sand filters are ideal for pools in areas with minimal debris but may not be the best choice if your home pool is frequently exposed to heavy leaf fall or fine debris.

If you are looking for a good pool sand filter, Pool King's Fiberglass Topmount Sand Filter is a fine option! The pool sand filter comprises 7 layers to give more effective and efficient cleaning.

2. Cartridge Pool Filter

Cartridge filters are gaining popularity among pool owners for their superior filtration capabilities and low maintenance requirements. These filters use a pleated cartridge made of polyester or other materials to trap particles as water passes through. Cartridge pool filter excels at capturing both large and small debris, making it a top choice for those seeking ideal pool water quality.

Advantages of Cartridge Pool Filter

What makes a stand out? A cartridge filter has remarkable efficiency in removing fine particles, leading to clearer water and reduced chemical usage. Cartridge filters also require less frequent cleaning compared to sand filters. You only need to remove and clean the cartridge element once or twice a season, depending on pool usage and water conditions.

Another advantage of cartridge filters is their compact size, which can save space in your pool equipment area. This makes them ideal for smaller residential pools or situations where space is limited.

Limitations of Cartridge Pool Filter

However, it is important to note that a cartridge filter may have a slightly higher initial cost compared to sand filter, but its long-term benefits in terms of water clarity and lower maintenance costs often make it a wise investment.

For reliable filtration, Pool King's Single Element Cartridge Filter is an excellent option. Its filter construction is robust, UV resistant and non-corrosive for extended life. With two input ports, the intake plumbing can be positioned at either 900 or 1800 from the output, providing greater installation flexibility.

3. DE Filters

Diatomaceous earth (DE) filters are the gold standard when it comes to pool filtration. A DE pool filter uses a fine powder made from fossilized diatoms as the filter media. DE pool filters offer exceptional filtration capabilities, capable of capturing particles as small as 2-5 microns, which is significantly smaller than what sand or cartridge filters can achieve.

Advantages of DE Filters

DE filters are renowned for their ability to provide the clearest and most sparkling pool water. They are the go-to choice for pool owners who demand the highest water quality. If you are a perfectionist when it comes to water clarity or if you have a pool in an area with heavy debris, a DE pool filter is the best option.

Limitations of DE Filters

Maintenance-wise, DE pool filters require more attention than sand or cartridge filters. They need to be backwashed and recharged with DE powder periodically, requiring more resources than other filters. However, the exceptional filtration performance justifies the extra effort for many pool enthusiasts. 

Choosing the Right Filter for Your Residential Pool

Now that we have discussed the primary types of pool filters, let's look into how to choose the right one for your residential pool. Your decision should be based on several factors:

1) Pool Size and Usage

§ For small to medium-sized pools with moderate use, a cartridge pool filter can provide excellent filtration without needing frequent maintenance.

§ Larger pools or those with heavy use may benefit from the exceptional filtration a DE pool filter offers.

§ Sand filters are suitable for small to medium-sized pools in low-debris areas.

2) Water Quality Goals

§ If you prioritize crystal-clear water and are willing to invest in maintenance, a DE filter is the top choice.

§ Cartridge filters strike a good balance between water clarity and maintenance effort.

§ A pool sand filter is adequate for maintaining generally clear water with minimal maintenance.

3) Budget

Consider your initial budget as well as long-term maintenance costs. While pool sand filters are the most budget-friendly initially, cartridge filters offer good value over time and DE pool filters are a premium choice.

4)  Debris and Water Conditions

Evaluate the type and amount of debris your pool encounters. DE filters are best for fine debris, while cartridge filters work well for various debris types. You should also consider your water's hardness and mineral content; DE pool filters can handle hard water better.


Choosing the right swimming pool filter for your home pool depends on various factors, including pool size, water quality goals, budget, available space, debris and water conditions. Each type of filter—sand, cartridge and DE—has its own advantages and disadvantages.


Ultimately, the best pool filter for your swimming pool is the one that aligns with your specific needs and preferences. Consider your priorities, consult with a pool professional if needed and make an informed decision to ensure your pool water remains clean and inviting throughout the swimming season.
