how to clean and reuse a pool filter

Pool filters are an important part of pool maintenance. They help to keep your pool water clean and sparkling by filtering out dirt, debris, and other contaminants. But after a certain amount of time, pool filters get clogged and require cleaning. Many pool owners end up replacing their filters when they get dirty, but with a little bit of effort and attention, you can clean and reuse your pool filter, saving you both money and time. In this article, we will guide you on how to clean and reuse a pool filter with simple steps.

What are Pool Filters?

Pool filters are designed to remove unwanted debris, microbes, and even algae from your pool's water. They are available in different types - sand, cartridge, and diatomaceous earth (DE). The most popular types of pool filters are sand and cartridge filters, and they work differently to keep your pool clean.

Sand filters consist of a large tank filled with sand, which acts as the filtering medium. The water is pumped through the sand, and the sand traps debris and contaminants, leaving clean water to flow back into the pool. Cartridge filters, on the other hand, use paper or polyester filters to trap debris, and they require less cleaning during the pool season.

Why Clean and Reuse a Pool Filter?

Cleaning and reusing a pool filter is essential for maintaining clean and healthy pool water without breaking the bank. Replacing a pool filter is expensive, and it's not something you want to do frequently, especially if you have a large pool. By cleaning and reusing your filter, you extend its life and save yourself money in the long run. You also contribute to the environment by reducing waste, as old pool filters can cause a significant amount of waste in landfills.

Steps to Clean and Reuse a Pool Filter

Cleaning and reusing a pool filter is not rocket science. However, it requires a bit of attention to detail and following the correct steps. Here are simple steps to follow when cleaning and reusing a pool filter.

1. Turn off the Power and Release Pressure

Before starting the cleaning process, turn off your pool pump's power to avoid any accidents. Next, release the air pressure from the filter by turning the air release valve counter-clockwise. This releases any pressure that may have built up in the tank and helps to prevent the filter from cracking.

2. Remove the Filter from the Pool System

After releasing the pressure, remove the filter from the pool system. There are two ways to do this, depending on the type of pool filter you have. For sand filters, switch the handle on the valve to the "BYPASS" or "RE-CIRCULATE" position to relieve pressure, and then turn off the pump before removing the lid from the valve. For cartridge filters, turn off the pump and remove the filter from its housing.

3. Clean the Filter

Once you have removed the filter from the pool system, it's time to clean it. Use a hose with a high-pressure nozzle to remove any debris that may have accumulated on the filter. Be gentle when cleaning the filter, taking care not to damage the filter's pleats or cartridges.

For sand filters, the backwashing process should be done at this stage. Simply place the filter in the backwash position and let the water run through the filter for 3-5 minutes, or until the water runs clear.

For cartridge filters, use a filter-cleaning solution such as muriatic acid or a specially formulated cartridge cleaner. A thorough cleaning will help to eliminate any residue that may not be visible but will reduce the filter's efficiency.

4. Reassemble the Filter

Once the filter is clean and dry, reassemble it back into the pool system. Make sure all connections are tight and secure, then replace the air release valve.

5. Restart the System

After reassembling the filter, restart the pool system and check for leaks. Once you're sure there are no leaks, switch the handle back to the "FILTER" position and start enjoying your clean pool.

Conclusion

Cleaning and reusing a pool filter can save you money, help keep your pool clean, and reduce waste. With the easy steps above, you can save yourself the trouble of frequently replacing pool filters and extend the life of your current filter. It’s recommended to clean it once a month during the peak pool season, but with proper maintenance, you could use it for a whole season without the need for replacements. A clean and properly maintained filter is an essential part of an organized pool care routine.
