How Much Does a Pool Filter Cost to Run?

Swimming pools are a great addition to any home, providing a fun and refreshing way to beat the heat during the summer months. However, owning a pool comes with its own set of responsibilities, and one of them is keeping the water clean and clear. A pool filter plays a crucial role in ensuring that the water remains free of debris and bacteria, but it also comes with some costs. In this article, we will delve into the details of how much a pool filter costs to run and investigate some ways to cut down on these expenses.

Understanding the Different Types of Pool Filters

Before we dive into the cost aspect, it's important to understand the different types of pool filters available in the market. There are three main types of pool filters:

1. Sand Filters: These filters use a layer of sand to trap particles and debris. They are affordable to purchase but require more frequent backwashing, which can increase water consumption.

2. Cartridge Filters: Cartridge filters use replaceable cartridges to filter out debris. They are more expensive than sand filters but require less maintenance and are more effective.

3. DE Filters: Diatomaceous Earth (DE) filters use microscopic fossilized remains of diatoms to trap debris. They are the most expensive but the most effective as well, providing the highest level of cleanliness for your pool.

Understanding the Cost to Run a Pool Filter

The cost of running a pool filter largely depends on the size of the pool, the type of filter, and the electricity rates in your area. However, on average, a pool filter can cost anywhere from $50 to $200 per month to run. Here are some factors that affect the cost:

1. Pump Size: The larger the pump, the more electricity it will consume to run the filter.

2. Filter Type: As mentioned earlier, DE filters are the most expensive to maintain and run, while sand filters are the cheapest. Cartridge filters fall somewhere in between.

3. Pool Size: The larger the pool, the longer the pump needs to run to filter the water, leading to higher electricity consumption.

4. Electricity Rates: Depending on where you live, the cost of electricity can vary significantly.

Tips to Reduce Pool Filter Costs

Now that we know the factors that affect the cost of running a pool filter, let's look at some ways to reduce these costs:

1. Optimize Pump Size: Consult a professional to ensure that your pump is properly sized for your pool. A smaller pump can help you save on electricity costs.

2. Invest in a High-Efficiency Pump: Upgrading to a high-efficiency pump is a smart investment as it can help you save on electricity bills in the long run.

3. Install a Programmable Timer: A programmable timer allows you to set the filter's run time and avoid unnecessary filtering.

4. Regular Maintenance: Regularly cleaning and maintaining your pool filter can help it run more efficiently and extend its lifespan.

5. Cover Your Pool: Covering your pool when not in use can significantly reduce water evaporation and, in turn, save you on water and electricity bills.


In conclusion, owning a pool comes with its own set of expenses, one of which is running the pool filter. While the cost may vary depending on several factors, there are ways to reduce these costs. Investing in a high-efficiency pump, optimizing pump size, and regular maintenance can help bring down the cost to run a pool filter. It's important to weigh the initial costs versus the long-term savings and select a filter type that suits your budget and maintenance schedule.
