Safer, healthier drinking water with efficient water filtration
Engineers across the world trust Porex for porous filter solutions to address complex design and engineering challenges in the consumer and recreational water filtration industries. With decades of material science expertise and filtration application experience, our global operations ensure high reproducibility and reliability of filter products throughout the supply chain.
POREX® filters are used in a variety of water filtration products for drinking water systems in order to:
- Improve filter performance due to rigid structure and media compaction
- Increase filter life as our pre-filters and media support effectively filter out particles that cause fouling.
- Incorporate carbon for chlorine removal and taste enhancement in low pressure systems
Carbon Block Pre-Filters
Enhance pre-filtration with longer life and durability
Media Support Tubes
Maximize filtration efficiency and structural integrity
Melt Blown Filter Cartridges
Reliable performance in the most challenging environments
Media Support Disks
Maximize filtration efficiency and lifespan of filtration cartridges
Sports Water Bottle Filters
Enhance taste through sustainable filtration
Carbon Block Pre-Filters
Enhance pre-filtration with longer life and durability
POREX® carbon block pre-filters – also called seamless filters –
offer advanced pre-filtration. Thick polyolefin walls allow for maximum
flow and high efficiency, quickly removing sediment particulates from
water. The seamless, unified design enables easy assembly while
eliminating the risk of downstream contamination due to seam failure.
With fully customizable dimensions, fiber sizes, pore sizes and densities, our carbon block pre-filters:
- Eliminate the need for a separate sediment filter – combines sediment and carbon block filtration in one step.
- Extend the life of carbon filters–Material quickly removes sediment particulates to extend product life.
- Eliminate challenges from seam failures–Durable one-piece construction of the material eliminates issues caused by seam failures.

Media Support Tubes
Maximize filtration efficiency and structural integrity
POREX® media support tubes, sleeves, outer wraps and cores improve the filtration and structural integrity of water filtration cartridges.
Specifically designed for drinking water applications, our media support tubes:
- Extend primary filter lifespan–Removal of carbon fines, dirt, rust and sediment extends the primary filter lifespan, including carbon blocks and RO filtration.
- Maximize flow and filtration efficiency–Structural integrity of porous tubes maximizes efficiency while removing sediment.
- Enhance filtration – Ability to tightly pack media into tubes prevents poor filtration due to channeling.

Melt Blown Filter Cartridges
Reliable performance in the most challenging environments
Engineered for absolute fiber purity and consistency, POREX® melt blown filter cartridges provide optimized dirt-holding capacity, low-pressure drop, high filtration efficiency, and long lifespans. Entirely made of melt blown nylon microfibers, our melt blown filter cartridges are binder-free and thermally treated for reliable performance in the most challenging environments.
Specifically designed for drinking water applications, our melt blown filter cartridges:
- Increase efficiency–Cartridges are engineered for optimal dirt-holding capacity and high filtration efficiency.
- Provide chemical and thermal resistance–Nylon structure provides exceptional chemical and thermal resistance
Media Support Disks
Maximize filtration efficiency and lifespan of filtration cartridges
Media support disks improve the filtration and structural integrity of water filtration cartridges.
Specifically designed for drinking water applications, our media support disks:
- Extend media lifespan–Removal of carbon fines, dirt, rust and sediment extends media lifespan.
- Maximize filtration efficiency–Structural integrity of porous tubes maximizes efficiency while removing sediment.
- Enhance filtration – Ability to tightly pack media into tubes prevents poor filtration due to channeling.

Sports Water Bottle Filters
Enhance taste through sustainable filtration
POREX® carbon filters for water bottles are designed to remove sediment, lead, and chlorine in a single-pass filtration process that meets NSF Class I standards. With its optimal pore size that minimizes flow resistance, our carbon filters also allow enough residence time for removal of chlorine and lead.
Designed for consumer water bottles, our carbon filters offer an easy, effective way to filter out pollutants and generate clean drinking water for consumers.
Available in custom-designed geometries and filter media, our water bottle filters:
- Effectively remove chemicals–Filters chlorine for up to 50 gallons of tap water and effectively removes high solids and odors.
- Reduces environmental footprint–Replaces over 350 single-use water bottles, reducing impact on local landfills.
- Decrease end user cost – Significant savings vs. single use water bottles
