How to Properly Maintain Your Pool Filter

by dailynewsvalley.com

Owning a pool can be a great way to relax and cool off during the hot summer months. However, a key component of keeping your pool sparkling clean and ready for swimming is maintaining your pool filter. Proper maintenance of your pool filter is essential for keeping your pool water clean and clear, and for preventing costly repairs down the line. In this article, we will discuss how to properly maintain your pool filter so you can enjoy your pool all summer long.

Types of Pool Filters

There are three main types of pool filters: sand filters, cartridge filters, and diatomaceous earth (DE) filters. Each type has its own pros and cons, but all require regular maintenance to keep your pool water clean.

1. Sand filters: Sand filters are the most common type of pool filter and are relatively low maintenance. They work by trapping debris and impurities in the sand, allowing clean water to pass through. To maintain a sand filter, you will need to backwash it regularly to clear out trapped debris and replace the sand every five years or so.

2. Cartridge filters: Cartridge filters are a popular choice for pool owners because they are easy to maintain and cost-effective. They work by trapping debris on a pleated filter cartridge, which can be easily removed and cleaned with a hose. Cartridge filters should be cleaned every few weeks and replaced once a year.

3. DE filters: DE filters are the most efficient type of pool filter, trapping even the smallest particles in the diatomaceous earth powder that coats the filter grids. To maintain a DE filter, you will need to backwash it regularly and add fresh DE powder as needed.

Now that we have discussed the different types of pool filters, let’s delve into how to properly maintain your pool filter.


Regardless of the type of pool filter you have, backwashing is an essential part of proper maintenance. Backwashing involves reversing the flow of water through the filter to flush out trapped debris and impurities. To backwash your pool filter, follow these steps:

1. Turn off the pool pump.

2. Turn the filter valve to the “backwash” position.

3. Turn the pool pump back on and let it run for a few minutes until the water in the sight glass runs clear.

4. Turn off the pool pump again.

5. Turn the filter valve back to the “filter” position.

6. Turn the pool pump back on and resume normal filtration.

Backwashing should be done at least once a month, or more frequently if you notice a drop in water pressure or the water looks cloudy.


In addition to backwashing, your pool filter will also need to be cleaned regularly to remove trapped debris and maintain proper filtration. The frequency of cleaning will depend on the type of filter you have, but as a general rule of thumb, you should clean your filter every few weeks. To clean a cartridge filter, simply remove the cartridge and hose it down with a high-pressure nozzle. For DE filters, you may need to disassemble the filter and clean the grids with a hose and brush.


Over time, the filter media in your pool filter will become clogged with debris and will need to be replaced. For sand filters, the sand should be replaced every five years or so. Cartridge filters should be replaced once a year, and DE filters will need to be recharged with fresh DE powder every few months. It is important to follow the manufacturer’s recommendations for replacing the filter media to ensure proper filtration and prevent damage to your pool equipment.

Routine Maintenance

In addition to regular backwashing, cleaning, and replacing the filter media, there are a few other key maintenance tasks that should be part of your pool filter maintenance routine:

1. Check the pressure gauge: Your pool filter has a pressure gauge that indicates when it is time to backwash or clean the filter. Monitor the pressure gauge regularly and backwash or clean the filter as needed.

2. Check for leaks: Inspect the filter housing and plumbing connections for any signs of leaks. Leaks can cause water loss and damage to your pool equipment, so it is important to address them promptly.

3. Maintain water chemistry: Proper water chemistry is essential for keeping your pool filter and equipment in good working order. Test your pool water regularly and adjust the pH, chlorine, and alkalinity levels as needed.

By following these tips for properly maintaining your pool filter, you can ensure that your pool water stays clean and clear all season long. Remember that a well-maintained pool filter is essential for keeping your pool in top condition and preventing costly repairs. With regular maintenance and care, you can enjoy your pool to the fullest and make the most of the summer season.
