Should I Run My Pool Filter 24/7?

Summer is in full swing, and your pool is the perfect oasis to cool down during the hot days. However, with owning a pool comes the responsibility of maintenance, and one of the questions that pool owners often ask is whether they should run their pool filter 24/7. To help you out, we’ve gathered all the essential information on pool filters and their operations to answer this frequently asked question.

What Is The Purpose Of A Pool Filter?

Before we dive into the topic at hand, it’s essential to understand the purpose of a pool filter. The primary function of a pool filter is to prevent unwanted debris, dirt, and other small particles from clogging the pool circulation system, which can ultimately damage your pool equipment. A pool filter ensures that the water in your pool remains clean and clear, free of any contaminants that could cause harm or discomfort to you and your loved ones.

Types Of Pool Filters

There are three main types of pool filters; Sand filters, cartridge filters, and DE (Diatomaceous Earth) filters. Sand filters are the most common and are designed to trap particles by passing the water through sand. Cartridge filters work similarly, but instead of sand, they use a cartridge that traps particles. DE filters are the most efficient and have a fine mesh of fossilized diatoms that are coated on a grid which catches even the smallest particles.

Should I Run My Pool Filter 24/7?

There’s no straightforward answer to this question as some factors affect the optimal running time of your pool filter. Here are some points to consider:

Pool Size

The size of your pool plays a significant role in determining the optimal running time for your pool filter. The larger your pool, the longer your filter must run to ensure that all the water is filtered.

Bather Load

The number of people who use your pool regularly affects the amount of debris and contaminants that enter the pool. A high bather load means that more debris enters the pool, requiring a longer running time for the filter.


External factors such as wind, rain, and even sunlight affect the optimal running time of your pool filter. High winds carry more dirt and debris into the pool, while rainwater can affect the PH level of your pool water. It’s recommended to run your pool filter a little longer during bad weather to ensure that these factors do not have a significant impact on your pool.

Energy Costs

Running your pool filter for an extended period of time can lead to an increase in energy costs. While a few extra hours of running time may not seem like much, it can result in a substantial increase in your electricity bill at the end of the month.

The Bottom Line

So, should you run your pool filter 24/7? The answer is no. Running your pool filter for too long can be wasteful and increase your energy costs without any added benefits. Most experts recommend running your pool filter for at least eight hours a day, but this still largely depends on the factors listed above. It’s essential to strike a balance between the running time of your pool filter and energy costs while ensuring that your pool remains clean and clear.

In conclusion, your pool filter works tirelessly to keep your pool clean and clear, and it’s essential to give it the optimal running time to ensure that it does its job correctly. By considering the factors listed above and striking a balance between running time and energy costs, you can enjoy your pool without any worries.
