How to Properly Clean Your Pool Filter: A Complete Guide

If you own a pool, you know how essential it is to keep it clean. A properly functioning pool filter is the key to maintaining clean and clear pool water. A dirty or clogged filter can lead to numerous pool problems such as cloudy water, algae growth, and even circulation problems. So, it’s crucial to know how to properly clean your pool filter. In this article, we’ll provide a step-by-step guide on how to clean different types of pool filters.

1. Types of Pool Filters

There are three types of pool filters: sand filters, cartridge filters, and diatomaceous earth (DE) filters. Each type operates differently and requires a different cleaning process.

- Sand Filters: A sand filter uses sand to trap debris and other contaminants. Water passes through the sand, and the clean water returns to the pool.

- Cartridge Filters: Cartridge filters use a paper-like material to trap debris. As the filter gets clogged, water flow decreases.

- DE Filters: Diatomaceous earth filters use DE powder to coat a grid with microscopic openings. Water passes through the grid, and the DE powder traps even tiny debris particles.

2. When to Clean Your Pool Filter

The frequency of cleaning your pool filter depends on various factors like pool usage, weather, and filter type. As a general rule, sand filters must be cleaned every few months, cartridge filters every two to three weeks, and DE filters at least once a year. However, if you notice a decrease in water flow, higher pressure, or murky water, it’s best to check your filter and clean it if necessary.

3. Tools Required

- Backwash Hose: Needed for sand filter cleaning.

- Pool Filter Cleaner: A pool-specific cleaning formula to remove oil, grease, and stubborn debris.

- Water Hose: To rinse the filter clean.

- Pressure Gauge: To measure your filter’s PSI.
