Recirculation on Pool Filters: What it is, How it Works, and Why You Need it

If you happen to own a swimming pool, then you know how important it is to keep it clean and safe for everyone to use. This is where a pool filter comes into play. A pool filter is designed to remove dirt, debris, and other contaminants from the water and keep the pool clean. One important component of a pool filter system is recirculation. In this article, we will explore what recirculation on pool filters means, how it works, and why you need it.

What is Recirculation on Pool Filters?

Recirculation is the process by which pool water is circulated through the filter system multiple times to ensure that it is purified properly. In simple terms, recirculation means that the water is partially or completely pumped back into the swimming pool after passing through the pool filter. This process is necessary to maintain clean, healthy pool water.

How Does Recirculation on Pool Filters Work?

The recirculation process on pool filters works in three stages. First, after the water enters the filter system, it passes through the pump, which feeds it into the filter. Second, the filter removes dirt, debris, and other contaminants from the water. Lastly, after the water passes through the filter, it is either immediately returned to the swimming pool or further processed through other equipment such as heaters, motors, or chemical dispensers.

Why You Need Recirculation on Pool Filters

Recirculation is crucial for maintaining clean and safe pool water. When used properly, a pool filter system with recirculation can reduce the amount of dirt, debris, and other unwanted substances in your pool water, which can cause health issues for swimmers. Additionally, recirculation helps to maintain the effectiveness of other pool equipment, such as heaters and motors. Lastly, a pool filter system with recirculation can save you money by reducing the amount of water and chemicals you need to add to your pool.

Maintaining the Recirculation System for Optimal Pool Maintenance

To ensure that your pool filter system maintains optimal performance, it is important to maintain the recirculation system. One way to do this is by backwashing the pool filter regularly. Backwashing involves reversing the flow of water through the filter to remove any debris trapped inside. You should also regularly clean the skimmer basket and the pump strainer to prevent blockages and maintain proper water flow.

How to Choose the Right Pool Filter System for You

When it comes to choosing the right pool filter system for your pool, there are several factors to consider. These include the size of your pool, the type of contaminants you anticipate, and your budget. In general, there are three types of pool filters: sand, cartridge, and DE (diatomaceous earth) filters. Sand filters are the most popular and affordable option, while cartridge and DE filters provide higher levels of filtration.


Recirculation on pool filters is an important process that ensures clean and safe pool water for swimmers. By understanding how recirculation works and maintaining your pool filter system, you can enjoy your swimming pool without worries about contaminants. If you are considering purchasing a pool filter system, it is important to understand your options and choose the right one for your needs.
