The chemical and bacterial resistance of the Series PE polyester media makes these cartridges suitable for potable water, light industrial applications, swimming pool and spa, and well water applications. The durable non-woven polyester fabric is reusable, while being pleated to maximize its dirt holding capacity and extending the time period between changes.

The 2 5/8" diameter by 9 3/4" length has 4 ft² of fabric media while the larger 4 1/2" diameter by 9 3/4" long version has more than triple the square footage of filtration media.
