Pool Filter Cartridge Media Description

The 100% spunbond polyester media in the pool filter cartridge is pleated with sharp, crisp edges (this is a sign of quality manufacturing) to assist in trapping the dirt and debris. Again a cheaper quality pool filter cartridges will have pleats that are rounded and not crisp.  This media comes in different weights or thicknesses, the thicker or heavier the media the more filtering capability it will have. The industry standard is a 3 ounce media with 4 ounce media being heavier duty.  Anti Microbial is a 4 ounce media with microban technology spun into the fibers (see below for more explanation)

Microns refers to the size of particles in the water, i.e. table salt is measured at 90 microns. Anything smaller than 35 microns is not visible with the human eye. Media will often be classified depending on the Micron size.

Following is the explanation of the different media weights:

Standard Duty:  3 ounce 100% spunbond polyester media is the most common in the pool and spa industry. It will filter down to about 30 - 40 microns.

Heavy Duty: 4 ounce 100% spunbond polyester will filter down to about 15-20 microns. This heavier material will provide you with slightly better water clarity than the standard 3 ounce media and will usually last a little longer.

Anti-Microbial: This product is explained in details on the page “Explanation of Microban”. Basically anti-microbial technology is built into the product during the manufacturing process and becomes an un-separable part of the spunbond polyester. When microbes such as fungi, mold and bacteria etc. reach the filter, the Microban attacks these microbes and disrupts the cell function so the microbe cannot function, grow or reproduce.
