How to Determine Square Footage of Pool Filter

Pool filters are an essential part of any swimming pool, ensuring that the water remains clear and clean. However, it is important to ensure that your pool filter is the correct size for your pool to function efficiently. One important factor in determining the size of your pool filter is the square footage of your pool. In this guide, we will take you through how to determine the square footage of your pool filter.

1. Understanding what square footage is

Before we get into the nitty-gritty of measuring your pool filter, it is important to understand what square footage means. Simply put, square footage is the area of a two-dimensional object or space. In terms of your swimming pool, this refers to the surface area of your pool.

2. Measuring the surface area of your pool

To determine the square footage of your pool filter, you first need to calculate the surface area of your swimming pool. This can be done by measuring the length and width of your pool and multiplying the two measurements together. For example, if your pool is 20 feet long and 10 feet wide, the surface area would be 200 square feet.

3. Determining the flow rate of your pool

The flow rate of your pool refers to the amount of water that is circulated through your pool filter each hour. This is measured in gallons per minute (GPM) or gallons per hour (GPH). To determine the flow rate of your pool, you will need to refer to your pool’s pump specifications or consult with a professional.

4. Knowing the filter’s minimum flow rate

Once you know the flow rate of your pool, you need to ensure that your pool filter has a minimum flow rate that is equal to or greater than your pool’s flow rate. The minimum flow rate of your pool filter is determined by the square footage of your pool filter. A rule of thumb is that there should be at least one square foot of filter area for every 10,000 gallons of water in your pool.

5. Calculating the square footage of your pool filter

To determine the square footage of your pool filter, you need to know the model number or size of your pool filter. Typically, this information can be found on the filter housing or in the manufacturer’s manual. Once you have this information, you can refer to a pool filter sizing chart or contact the manufacturer to find out the square footage of your pool filter.

In conclusion, determining the square footage of your pool filter is an important step in ensuring that your swimming pool remains clean and clear. By calculating the surface area of your pool, determining the flow rate of your pool, knowing the filter’s minimum flow rate, and calculating the square footage of your pool filter, you can ensure that your pool has the right filter to keep the water clear and healthy for swimming.
