how to change pool filter


Author: Poolking - Swimming Pool Equipment Manufacturer


Having a pool can be a lot of fun in the summer, but it requires maintenance to keep it clean and safe for swimming. One of the essential parts of any pool maintenance routine is the pool filter. A pool filter helps trap unwanted dirt and debris, keeping the water clear and clean. Over time, a pool filter can become clogged and dirty, leading to decreased efficiency and possibly even damage. In this article, we'll outline the steps for how to change a pool filter, so you can keep your pool in top condition.

Subheading 1: Determine the Type of Filter

Before you begin the process of changing your pool filter, you will need to determine which type of filter your pool uses. There are three main types of pool filters: sand, cartridge, and diatomaceous earth (DE). Each type of filter requires different steps to replace, so be sure to identify your filter before proceeding.

Subheading 2: Gather Your Tools and Materials

Once you've determined the type of filter your pool uses, you'll need to gather the necessary tools and materials to change it. Some tools you may need include a screwdriver, pliers, and a filter wrench (if applicable). You'll also need the appropriate replacement filter, which can be found at most pool supply stores.

Subheading 3: Shut off Power and Drain Water from Filter

Before you begin working on the filter, you'll need to shut off power to the pool and the filter. Next, you'll need to drain the water from the filter tank. To do this, look for a valve near the bottom of the filter and turn it counterclockwise to release the water.

Subheading 4: Remove the Old Filter

Now that the filter is drained, you can begin to remove the old filter. Depending on the type of filter, this may involve unscrewing it from the tank or simply pulling it out of the housing. Be sure to follow the manufacturer's instructions to avoid damaging the filter or causing a mess.

Subheading 5: Install the New Filter

Once you've removed the old filter, it's time to install the new one. Again, depending on the type of filter, this may involve screwing it into place, inserting it into the tank, or reassembling the housing. Be sure to follow the manufacturer's instructions carefully to ensure proper installation.


Changing a pool filter may seem like a daunting task, but with the right tools and a little know-how, it's a job that can be done easily and quickly. By following the simple steps outlined in this article, you can keep your pool filter working efficiently and extend the life of your pool. So next time you notice your pool water looking a little murky, don't hesitate to change your filter and get back to enjoying your pool!
