How to Clean Pool Filter: Essential Maintenance Guide
How to Clean Pool Filter?
To clean a pool filter, start by identifying the type of filter you have: cartridge, sand, or D.E. filters.
Cartridge filters should be cleaned every other week by removing the large nut at the top and hosing off the filter.
Sand filters, the most common type, can be cleaned by using the multiport valve to backwash and rinse the filter.
D.E. filters require occasional addition of D.E. powder for efficiency.
Regular cleaning of your pool filter, every few weeks or once a month, is necessary to maintain water clarity and flow.

Did You Know?
1. The sand used in pool filters is not actually regular beach sand but specially graded filter sand. It has a larger particle size and more uniform shape, allowing for better filtration efficiency.
2. Pool filters can be cleaned using a technique called backwashing. This process involves reversing the flow of water through the filter, flushing out trapped debris and contaminants. It is recommended to backwash the filter regularly to maintain its effectiveness.
3. One alternative to traditional sand filters is the diatomaceous earth (DE) filter. DE is a fine powder made from fossilized diatoms and provides superior filtration due to its microscopic structure, capturing even the tiniest particles in the water.
4. Cartridge filters, another type of pool filter, use a replaceable cartridge made of pleated fabric to trap debris. The advantage of cartridge filters is that they require less frequent cleaning compared to sand filters and offer a convenient maintenance option.
5. Properly cleaning pool filters is not only essential for water quality but also for energy efficiency. A dirty or clogged filter increases the strain on the pool pump, resulting in higher energy consumption. Regularly cleaning and maintaining pool filters can help save on electricity costs in the long run.
Signs Of A Dirty Pool Filter
It is crucial to clean pool filters regularly in order to maintain water clarity and flow. One of the first signs that indicate the need for cleaning is cloudy pool water. When the filter becomes dirty and clogged with debris, it is unable to effectively remove impurities from the water, resulting in a hazy appearance.
Another sign that your pool filter needs cleaning is elevated filter pressure. If you notice that the pressure gauge on your filter is reading higher than normal, it is a clear indication that the filter is struggling to push water through the system due to blockages.
Additionally, a decrease in return water pressure can also indicate the need for filter cleaning. If you notice that the water flow from the return jets has weakened, it is likely due to a dirty filter hindering the circulation.
- Cloudy pool water indicates the need for cleaning
- Elevated filter pressure is a clear indication of blockages
- Decreased return water pressure can be caused by a dirty filter

Types Of Pool Filters
There are three main types of pool filters: cartridge filters, sand filters, and D.E. filters.
Cartridge filters are commonly used in smaller above-ground pools. They have a large nut at the top which needs to be removed in order to access and clean the filter.
Sand filters, on the other hand, are the most common type of pool filter. They have a potbelly shape and the filter housing is usually made of plastic. These filters are controlled by a multiport valve located on top or in front of the filter.
Lastly, D.E. filters are cylindrical in shape and generally have a stainless steel or metal body. These filters use a special type of filter media called diatomaceous earth (D.E.) which enhances filtration. D.E. powder needs to be periodically added to the filter to maintain its efficiency.
Cleaning Frequency For Pool Filters
The frequency at which you should clean your pool filter depends on various factors such as the type of filter, the amount of leaves and debris in the pool, as well as your pool setup and location.
However, as a general rule of thumb, it is recommended to clean your pool filter every few weeks or at least once a month. Regular cleaning not only helps maintain water clarity and flow but also extends the overall lifespan of your pool system. Consistent and proactive maintenance is key in ensuring that your pool remains clean and enjoyable.
Cleaning Cartridge Filters
If you have a cartridge filter, it is important to clean it every other week in order to prevent permanent loss of efficiency. To clean a cartridge filter, follow these steps:
- Turn off the pool pump and release the pressure from the filter by:
- Opening the air relief valve or
- Removing the filter lid
- Remove the cartridge from the filter housing by unscrewing the large nut at the top
- Rinse off any large debris using a hose
- Soak the cartridge in a filter cleaning solution to remove any built-up oils and contaminants
- Once the cartridge has soaked for the recommended time, thoroughly rinse it with a hose
- Reassemble the filter by placing the cartridge back into the housing and screwing the large nut tight
Remember to always follow the manufacturer’s instructions for your specific cartridge filter model.
Note: Regular cleaning of your cartridge filter will ensure its efficiency and prolong its lifespan.
Cleaning Sand Filters
To clean sand filters, backwashing is the typical process used. Follow these steps:
- Turn off the pool pump.
- Set the multiport valve to the “backwash” position.
- Turn on the pump and let it run for a few minutes or until the water coming out of the waste line runs clear.
- When the water is clear, turn off the pump again.
- Switch the valve to the “rinse” position.
- Turn on the pump and let it run for approximately 30 seconds to ensure any remaining debris is flushed out.
- Finally, switch the valve back to the “filter” position to resume normal pool filtration.
It is important to note that sand filters will eventually require a sand replacement, usually every 3-5 years.
Cleaning D.E. Filters
D.E. filters require more intensive maintenance compared to cartridge and sand filters.
To clean a D.E. filter, follow these steps:
- Turn off the pump and release the pressure by opening the air relief valve or removing the filter lid.
- Locate the filter’s manifold and remove it from the filter body.
- Clean the manifold thoroughly, removing any accumulated D.E. powder and debris.
- Carefully remove the filter grids or fingers from the filter body and hose them down to remove excess D.E. powder.
- If necessary, soak the filter grids in a cleaning solution to remove stubborn stains.
- Reassemble the filter, ensuring a proper seal.
- Add the appropriate amount of D.E. powder, as recommended by the manufacturer, through the skimmer with the pump running.
- Monitor the filter pressure regularly to make sure it remains within the recommended range.
Taking care of your pool filter is essential for maintaining clean and clear water. Regular cleaning, appropriate for your specific type of filter, will ensure optimal performance and prolong the life of your pool system. By being proactive in this essential maintenance task, you can enjoy a sparkling pool all season long.
