Swimming Pool Filter Cleaner: Restore Your Filter’s Efficiency

Swimming pool filter cleaners are essential tools for maintaining the efficiency of your pool’s filtration system. A clean filter ensures clean, sparkling pool water and protects your pool equipment from dirt and debris.

Types of Swimming Pool Filter Cleaners

When maintaining a swimming pool, choosing the right filter cleaner is crucial for ensuring water clarity and hygiene. Here’s a detailed look at the types of swimming pool filter cleaners, focusing on cartridge, sand, and diatomaceous earth (DE) filters.

Understanding Cartridge Filter Cleaners

Cartridge filters use pleated polyester fabric to trap debris and particles. Cleaning these filters involves several steps to ensure they remain effective:

Basic Cleaning: Remove the cartridge from the filter housing and use a garden hose with a spray nozzle to wash off debris. Hold the nozzle at a 45-degree angle to clean between the pleats thoroughly.

Deep Cleaning: For more thorough cleaning, soak the cartridge in a filter cleaner solution. This can be a commercial filter cleaner or a mixture of trisodium phosphate (TSP) and water. Soak the cartridge for at least an hour or overnight for the best results.

Rinsing and Drying: After soaking, rinse the cartridge thoroughly to remove all cleaning solution and debris. Allow the cartridge to dry completely before reinserting it into the filter housing.

Regular cleaning is recommended when the filter pressure gauge reads 8–10 PSI above the normal operating level or every 3–6 months, depending on pool usage.

Exploring Sand Filter Cleaners

Sand filters use specially graded sand to trap particles as water passes through. The cleaning process, known as backwashing, involves reversing the water flow to remove trapped debris.

Backwashing: Turn off the pool pump, set the multiport valve to the backwash position, and turn the pump back on. Run the backwash until the water in the sight glass is clear, usually 2–3 minutes.

Rinsing: After backwashing, set the valve to the rinse position and run the pump for 1-2 minutes to resettle the sand.

Regular Maintenance: Backwash the filter when the pressure gauge reads 8–10 PSI above the clean starting pressure. Sand typically needs to be replaced every 5–7 years, depending on usage.

Sand filters are effective for removing particles down to 20–40 microns, making them suitable for most residential pools.

Comparing Diatomaceous Earth (DE) Filter Cleaners

DE filters use a fine powder made from fossilized diatoms to trap particles as small as 2–5 microns, providing superior water clarity.

Pre-Coating: Before use, DE powder is mixed with water to form a slurry and added to the filter. The powder coats the filter grids, creating a layer that traps debris.

Backwashing and Re-Coating: Similar to sand filters, DE filters require backwashing to remove trapped debris. After backwashing, new DE powder must be added to re-coat the grids.

Manual Cleaning: Periodically, the filter grids need to be removed and cleaned manually. This involves soaking the grids in a filter cleaner solution to remove oils and debris, then rinsing thoroughly before reassembly.

DE filters offer the highest level of filtration, capturing the smallest particles and reducing the need for chemical treatments. However, they require more maintenance and handling of DE powder, which can be messy
