How to Clean Above Ground Pool Filter: A Comprehensive Guide

Maintaining an above-ground pool can be quite a task, with keeping the water in pristine condition being the most challenging part. However, it is crucial to pay attention to the pool filter, as it helps in trapping unwanted debris and chemicals that enter the pool water. Cleaning the pool filter regularly ensures that it functions efficiently, preventing frequent breakdowns and pool water turning green.

If you're not entirely sure how to clean the above-ground pool filter, then this guide is for you. We aim to provide you with a comprehensive understanding of how to clean an above-ground pool filter so that you can keep your pool crystal clear.

Part 1: Types of Above Ground Pool Filters

There are three main types of above-ground pool filters, and cleaning each filter involves different steps. Here is a brief overview of the three types:

1. Sand filters - This type of filter uses sand as the primary filtration agent. The water flows through a layer of sand and removes dirt and debris.

2. Cartridge filters - In a cartridge filter, water passes through a layer of pleated mesh or polyester fabric that traps dirt particles.

3. Diatomaceous earth (DE) filters - A DE filter uses a porous, fossilized rock called diatomaceous earth as the filtration agent.

Part 2: Signs Your Pool Filter Needs Cleaning

Before diving into the cleaning process, it is essential to recognize when your pool filter requires cleaning. Here are some signs to look out for:

- Slow water flow: If water is not flowing out of the pool jets as it should, it could be due to a dirty pool filter.

- Dirty pool water: If you notice that the pool water is not as crystal clear as it usually is, the pool filter may be clogged.

- Pressure gauge reading: Most pool filters have a pressure gauge that indicates when it's time for cleaning. A reading above normal suggests that the filter needs cleaning.

Part 3: How to Clean Sand Filters

Cleaning a sand filter requires backwashing, which involves reversing the water flow to flush out trapped debris. Follow these steps to clean a sand filter:

1. Turn off the pool pump.

2. Turn the filter valve to the backwash setting.

3. Turn on the pool pump and let it run for around two minutes or until the waste water runs clear.

4. Turn off the pool pump and turn the filter valve to the rinse setting.

5. Turn the pool pump back on for 30 seconds to flush out any remaining debris.

Part 4: How to Clean Cartridge Filters

Cleaning a cartridge filter involves removing the cartridge filter and hosing it down to remove dirt and debris. Follow these steps to clean a cartridge filter:

1. Turn off the pool pump.

2. Open the filter cover and remove the cartridge filter.

3. Use a garden hose to rinse the filter from the top to the bottom to remove dirt.

4. For stubborn dirt, use a cartridge filter cleaner and soak the filter for a few hours.

5. Rinse the filter again until the water runs clear.

Part 5: How to Clean DE Filters

Cleaning a DE filter involves backwashing and adding fresh diatomaceous earth powder to the filter. Follow these steps to clean a DE filter:

1. Turn off the pool pump.

2. Turn the filter valve to the backwash setting.

3. Turn on the pool pump and let it run for around two minutes or until the waste water runs clear.

4. Turn off the pool pump and add the recommended amount of fresh diatomaceous earth powder.

5. Turn the filter valve to the filter setting and turn on the pool pump.

In conclusion, cleaning an above-ground pool filter is an essential part of pool maintenance. With proper cleaning, you can keep your pool crystal clear and extend the life of your pool filter. Remember to follow the steps and precautions mentioned in this guide when cleaning your pool filter. Happy swimming!
