How Long Should I Run Intex Pool Filter?

If you're a proud owner of an Intex pool, you know that keeping it clean and sparkling is not only necessary for its longevity but also for your own health and comfort. The Intex pool filter is an essential tool that helps keep your pool clean and free of debris, dirt, and harmful bacteria. But how long should you run your Intex pool filter? Here are some tips to help you keep your pool clean and healthy.

Understanding Your Filters

The first step in determining how long you should run your Intex pool filter is to understand how the filter works. There are three types of Intex pool filters: sand, cartridge, and pump. Each filter has different operating times, and you need to know what type you have before you can set a schedule.

Sand Filters

If you have a sand filter in your Intex pool, you need to run it for at least eight hours every day. Sand filters have a slower flow rate, which means they require more time to filter the water. Eight hours should be enough time to ensure that your pool stays clean and clear of debris.

Cartridge Filters

The Intex pool cartridge filter is the most commonly used type of filter in the market. It is convenient and easy to clean. However, it requires more maintenance and frequent cleaning than the sand filter. A cartridge filter should run for at least six hours a day. You may need to change the cartridge every two weeks, depending on how frequently you use your pool.

Pump Filters

If you have a pump filter, you need to run it for a minimum of six hours daily. The pump filter has a higher flow rate than the other filters, which means it can filter water faster. However, it is more expensive than the sand and cartridge filters.

How to Choose the Right Filter

Choosing the right type of Intex pool filter depends on the size of your pool, the frequency of use, and the types of debris that you expect to find in your pool. If you have a large pool or expect to encounter a lot of debris, a sand filter may be a more suitable option. If you have a smaller-sized pool, a cartridge filter is suitable.

Maintaining Your Filters

After determining the type of Intex pool filter you have, you need to ensure that you maintain it for optimal performance. Cleaning your filter regularly ensures that it runs efficiently and prolongs its lifespan. It is essential to clean your filter at least once a week, or depending on usage, more often.


Backwashing is a cleaning technique used with sand filters. When your filter gauge shows that there is a decrease in pressure, it is time for backwashing. This is the process of reversing the water flow through the sand filter and discharging the dirty water through a waste line. After backwashing, you need to run the filter for an additional two minutes to ensure that it is clean.


After backwashing, you should always rinse the filter to ensure that all the dirt and debris are removed. This process involves running water through the filter. It helps to remove any remaining dirt, which could cause blockages and reduce the filter's performance.

Chemical Balancing

One essential factor in maintaining your Intex pool filter is keeping your water chemistry balanced. Chlorination helps kill harmful bacteria and algae in your pool. Too much or too little chlorine can cause filter blockages and slow down your filter's performance. Ensure that you maintain your chlorine levels between two and four ppm, according to the manufacturer's recommendations.


Running your Intex pool filter for the right amount of time is critical in ensuring that your pool stays clean and free of debris. The type of filter you have, the size of your pool, and the frequency of use determines how long you should run your filter. Regular maintenance is also important to ensure that your filter runs efficiently and prolongs its lifespan. Always keep your water chemistry balanced, and adhere to the manufacturer's recommendations in maintaining your filter. Your pool's health, longevity, and your swimming experience depend on it.
