Pool Filter Basics

A swimming pool is comprised of several components that keep the pool water in good condition. Each of the pool’s parts and equipment plays a major role and needs to be well-maintained to ensure that your swimming pool stays clean and the experience stays pleasant.

In this article, we’ll be focusing on pool filters, one of the most important pieces of equipment that enhances a pool’s overall operation and quality.

The Role of the Pool Filter

The main function of the pool filter is to keep the pool water clear. The filter captures large and small particles, and other impurities, that can cause water contamination or algae buildup. It works by pulling water from the pool through the skimmer and the main drain then sending the pool water through the filtration system.

Types of Pool Filters

1. DE Filters

The DE (diatomaceous earth) filter is the most popular filter for the Dallas area. It contains grids which attach to a top and bottom manifold. DE is added through the skimmer which is then pulled into the DE filter and coats the grids. When the pool systems run, water is pulled through the filter, and particles, etc., attach to the DE which is coated on the grids. This is the most effective system a swimming pool owner can have. A DE filter must be backwashed every six weeks or when the pressure is 10 pounds over a clean PSI, which is determined after a filter clean. The proper amount of DE must be added (see the package). Too much or too little can cause damage to the filters. Keep in mind sometimes they need to be cleaned sooner, depending on a pool’s environment (foliage, ducks, pets). If you backwash the filter (three times in a row) and the pressure does not come down, it’s telling you it needs to be cleaned. A rule of thumbs if filter cleans be done every six months for proper maintenance.

3. Cartridge Filter

The cartridge filter uses cartridges instead of grids, which need to be removed and cleaned every six months. It is not as effective as a DE filter. Based on our thirty years of experience, we would always recommend a DE filter because it is more effective to keep your pool clean.

3. Sand Filters

This type of filter uses sand to trap impurities when water is forced through it. The sand filter also needs to be changed every five to eight years. It is the least effective filter for the Dallas area. These are mostly used commercially, i.e., apartments.

Pool Filter Cleaning with Sterling Pool Service

Since the pool filter is responsible for removing particles, etc. from the water, regular filter cleanings need to be performed. For a DE filter, this means completely disassembling the filter – not just taking the filter top off and washing off the grids. The grids must be taken off of the manifolds and carefully inspected to see if there are any rips or tears. If there are, the grid(s) need to be replaced.
