A pool filter is a vital component of any pool's circulation system, providing filtration to keep the water clean, clear, and free of debris. Filters for pools come in a variety of types, including: 

 ● Sand filters.

 ● Cartridge filters.

 ● and Diatomaceous earth (DE) filters.

When choosing a filter for your pool, you'll need to consider the size of the pool, the type of contaminants you want to remove, and the cost.


Sand filters are typically the most affordable option, while DE and cartridge filters provide the best filtration. Sand filters require backwashing on a regular basis to remove the accumulated dirt and debris. Cartridge and DE filters can be cleaned and reused, making them more cost-effective in the long run.


No matter which filters you select, proper maintenance is essential to keep your swimming pool clean and clear. It is essential to regularly inspect the filter to ensure it is free of clogs and debris.

Let's start to discuss the details of factors that should be considered before investing in filters for pools. With the proper knowledge, you can make better decisions.

Sand filters

Factors to Consider While Purchasing Filters for Pool

Factors to consider while purchasing filters for a pool include the size of the filter, the type of filter, the cost of the filter, the warranty, the efficiency of the filter, and the ease of maintenance. Additionally, it is essential to know the size of the pool and the kind of bacteria that will be filtered in order to determine the type and size of filter that is most appropriate.

1. Type of pool

The type of pool filter you need depends on your size and pool type. You will likely need a cartridge filter or a sand filter for an above-ground pool. For an in-ground pool, you may need a cartridge filter, sand filter, or a diatomaceous earth filter. You should consult a pool professional to determine the best filters for pool.

2. Filtration rate

The size of the swimming pool and the amount of debris that accumulates in it will determine the size and type of filter you will need. Generally, the larger the pool, the more filtration you will need. To determine the filtration rate you need, you will need to know the gallons of water in your pool and the turnover rate.


The turnover rate is defined as how many times the water in your pool should filter in a day. This is typically between 8 and 12 hours. Once you know the gallons of water in your pool and the turnover rate, you can calculate the gallons per hour (GPH) filtration rate you need. To calculate the GPH, divide the gallons of water in your pool by the turnover rate. For example, if you have a 15,000-gallon pool and the turnover rate is 8 hours, the GPH of filtration rate you would need is 1,875 GPH.

3. Maintenance requirements

Some filters for pool require regular maintenance and cleaning, while others require less maintenance. Some tips for care are:

 ● Regularly check the filter system for debris buildup and clean filters as needed.

 ● Monitor water clarity and adjust the filter system as necessary to maintain desired levels of clarity.

 ● Regularly check the pump, motor and all connections for proper operation and repair or replace components as needed.

 ● Clean the pool surfaces and maintain the pool deck to prevent slips and falls.

 ● Test and adjust the chemical levels of the pool water regularly to ensure proper sanitation.


 Inspect and repair any leaks that may occur:

 ● Keep the pool area clear of debris, leaves and other items that could clog the filter system.

 ● Schedule regular maintenance visits from a professional pool service technician to ensure the filter system is operating properly.

4. Cost

When selecting a pool filter, the cost is an essential factor to consider. Different pool filters have different prices, and the cost of a pool filter will vary depending on its size, type, and features. Some filters for pool are more expensive than others, but they may also offer better filtration and more features. Consider your budget and the cost of the filter before making a purchase.

5. Size

When selecting a pool filter, it is crucial to consider the size. The size of the filter depends on the area of the swimming pool and the type of filtration system you are using. If the filter is too small, it may not be able to efficiently clean the water, while a filter that is too large can cause excessive backwashing and excessive wear on the pump.

When to Replace the Pool Filters for Pool?

Generally, cartridge filters replace every 1-2 years, and sand filters should be replaced every 5-7 years. It is also important to check the filter pressure gauge regularly to ensure the filter is working correctly. If the pressure gauge is reading higher than normal, it may be time to replace the filter.
