Pleated Filters

Pleated configuration provides higher surface area than depth filters for greater dirt holding capacity and longer on-stream life including large diameter high flow filters

Read F.A.Q.


Cost-effective, pleated polypropylene filters with nominal ratings from 0.25 to 50 m. The fixed pore structure prevents dirt unloading at elevated pressures, and the pleated element offers an economical alternative to non-pleated filters.


Economical, absolute efficiency filtration in pore sizes ranging from 0.2 to 100 micron. The all-polypropylene construction incorporates a non-migrating pleated media.


Designed for cost-driven applications, this all polypropylene filter delivers absolute efficiency in a broad range of particle sizes. It is suitable for a wide range of applications and carries all the needed industry certifications to satisfy most critical requirements.


Pleated  filters manufactured with multiple layers of graded density, melt blown polypropylene. Nominal ratings of 0.1 to 10 micron provide outstanding protection for final membrane filters.


0.2 to 10 micron absolute rated, high-surface area pleated polypropylene filter cartridges provide low initial pressure drop, high dirt holding capacity, and a long, consistent service life.


Incorporating a polypropylene microfiber media over a polyethersulfone membrane, the serial layered cartridge design offers excellent retention characteristics and extended life to provide long lasting protection of downstream membrane filters.


Formulated with multiple layers of microfiber media to provide absolute rated efficiency from 0.45 to 40 microns. This innovative pleated/depth design combines the high surface area of pleated filters with a graded pore structure.


The borosilicate microfiberglass media with a natural positive charge exhibits exceptionally high dirt holding capacity. Available in nominal ratings from 0.2 to 30 micron with thermally bonded polypropylene components.


Utilizing the same media as in the GFC, the product has polyester support components for those applications requiring temperature ranges up to 230°F (110°C).


High efficiency filter element is constructed of pleated Borosilicate Microfiberglass media and stainless steel end caps. Offering excellent flow rates, exceptional service life, and high temperature capabilities, well suited to support a wide range of chemical and industrial applications.

High Flow

Large geometry to handle higher flows with fewer filter elements and excellent dirt holding capacity, extending the time between filter changeouts. Available in multiple configurations to retrofit most popular commercially available designs.


The Cyst Reduction filter contains an absolute 1 micron filter media designed to provide a minimum log reduction credit of >3.0 for cysts based on the test requirements of the Long term 2 Enhanced Surface Water Treatment Rule (LT2).

Frequently asked questions

How to remove heavy metals from water and wastewater?
Many MetSorb® adsorbents will remove heavy metals from water and wastewater. Please view our product pages for more information.
Are heavy metals in water? Do they pose a threat to human health?
The USEPA issued and regularly reviews/updates the National Primary Drinking Water Regulations (NPDWR).
How can I remove lead from water?
Many MetSorb® adsorbents will remove lead and other heavy metals from water. Please view our product pages for more information.
How much uranium is safe in drinking water?
The USEPA has issued and regularly reviews/updates the National Primary Drinking Water Regulations (NPDWR).
Why do MetSorb® adsorbents sometimes have a bad smell and how do we get rid of this odor?
MetSorb adsorbents are made from metal oxides and rarely have any noticeable smell. They can sometimes concentrate bacteria (specifically sulfur reducing) that may be present in the drinking water well source. While this type of bacteria is naturally found in many well sources and are considered harmless, the resulting “rotten egg” smell can be unpleasant. In order to remove the bacteria from the MetSorb® media bed, we recommend performing a 25-50 ppm chlorine shock for 12-24 hours. The system should then be rinsed with fresh water until no residual chlorine odor is noted. If bacteria count in the well water is high, this chlorine shock of the MetSorb® media may be required 2 or 3 times per year.
How can uranium be removed from well water?
One way uranium can be removed is through adsorption. MetSorb® HMRG has a selective affinity for uranium.
