what size pool filter

Swimming pools are an incredibly popular attraction in backyards all across America. They provide a fantastic way to stay cool during the hot summer months, and they are also an excellent spot for entertaining family and friends. However, keeping a pool clean and crystal clear can be a challenge without the proper equipment, especially if the pool filter is too small. In this article, we'll go over what size pool filter you'll need for your swimming pool and how to determine the right size.

Why the Size of Your Pool Filter Matters

For a swimming pool to remain clean and healthy, the water must circulate through the pool filter at least once a day. The pool filter serves as the main component in your pool's filtration system, removing dirt and debris and keeping your pool's water clear and safe for swimming. A small filter will not be able to handle the volume of water that needs to be filtered, which puts a strain on the filter and makes it less effective.

How to Determine the Right Size

When it comes to selecting the right size pool filter, it's essential to consider your pool's size and water capacity. The traditional rule of thumb for pool filters is that they should be able to filter all of the water in a pool within eight hours. However, this method doesn't take into account factors such as the pool's usage and environmental conditions, which can impact the amount of debris that gets into the pool.

1. Calculate Your Pool's Gallons

The first step in determining what size pool filter you'll need is to calculate your pool's gallons. One easy way to do this is to use an online pool volume calculator or a formula that takes into account your pool's shape and dimensions.

2. Determine Your Pool's Turnover Rate

The turnover rate is the amount of time it takes for your pool's water to travel through the filtration system once. A good turnover rate for most pools is at least once every eight hours. To calculate your pool's turnover rate, divide the number of gallons in your pool by the pump flow rate.

3. Choose the Right Size Filter

Once you know your pool's gallons and turnover rate, you can select the right size filter. Pool filters are measured in gallons per minute (GPM) or square footage. A filter's square footage represents the amount of filtering surface area it has. Generally, a filter should have one square foot of filtration area for every 10,000 to 15,000 gallons of water.

4. Consider Your Pool's Environment

Finally, it's important to take into account your pool's environment when selecting a filter. If you live in an area with a lot of trees and foliage, you may need a larger filter to handle the additional debris. If you have a lot of people using your pool regularly, you may also need a larger filter to handle the increased usage.

Conclusion

In conclusion, selecting the right size pool filter is crucial for maintaining a clean and safe swimming pool. By considering your pool's size, water capacity, turnover rate, and environment, you'll be able to choose the right filter to ensure that your pool remains clear and healthy all season long. Remember, a small filter may be cheaper initially, but it will cost you more in the long run due to increased maintenance and lower efficiency. So, don't skimp when it comes to selecting the right size pool filter!
