How to Clean Paper Pool Filter?

Summer season is just around the corner and it’s time to open up your pool. After months of laying dormant, your pool is bound to have accumulated dirt, debris, and bacteria. This may cause the pool water to become cloudy and even unsafe for swimming. Therefore, taking the time to clean your pool filter is essential.

Nowadays, many pool filters are made of paper. These filters are economical, easy to clean, and one of the most common types of pool filters in use today. As paper pool filters trap small particles like debris and leaves, they become congested over a certain period, causing a reduction in water flow. This ultimately affects the water filtration process in the pool. Therefore, it's necessary to clean your paper pool filter on a regular basis. But how do you go about cleaning them effectively? This article will provide you with a step-by-step guide on how to clean paper pool filters.

Why is it Necessary to Clean Paper Pool Filters?

Over time, pool filters become clogged with dirt, debris, and calcium deposits, which hinders the filter's ability to trap particles effectively. This reduced filtration process could lead to an increase in chlorine consumption and pool chemicals. Additionally, cleaning your pool filters regularly ensures that they remain in good condition and last longer. Therefore, it's essential to clean your paper pool filters to ensure crystal clear water, safe swimming condition, and prevent any potential damages to your filtration system.

Step-by-Step Guide on How to Clean Your Paper Pool Filters

1. Turn Off the Pool Pump: Before you begin to clean your paper pool filter, turn off the pool pump to allow the filter to release all pressure.

2. Remove the Paper Pool Filter: Locate the paper pool filter and carefully remove it from the filter housing. Be mindful not to damage it.

3. Inspect the Filter Cartridge: Once you have removed the filter cartridge, inspect it to ensure there are no tears or damage. If any damage is found, replace the filter cartridge with a new one.

5. Soak the Filter Cartridge: Next, prepare a cleaning solution by mixing one cup of trisodium phosphates (TSP) in a bucket of hot water. Soak the pool filter in the solution for at least an hour. This step will work its way into the filter's pleats to dislodge any accumulated dirt or debris.
