TRUPOR Performance Guide Rundown | Hollingsworth & Vose

Trupor(R) membrane microfiltration media is available today in Nylon as a rolled good in 10 inch (25.4 cm) width increments for 5.0 um, 1.2 um, 0.80 um, 0.65 um, 0.45 um, and 0.20 um nominal grades. Ask to learn more about H&V’s roadmap for sterilizing grades, polyethersulfone (“PES”) and Polyvinylidene Fluoride (“PVDF”). Trupor(R)’s Nylon grades are easily used in existing nylon membrane applications – pleated cartridges, capsules, flat sheets, and other unique form factors benefit from Trupor(R)’s improved flow rates and throughput.  

Microfiltration is the process of removing particles from a fluid using a porous membrane with a specific pore size. It’s an essential liquid filtration process in many industries, including food and beverage, industrial, bioprocessing, water treatment, and more. As the demand for liquid filtration increases, so does the demand for the products it creates. Improving microfiltration allows companies to introduce new products to the market, increase the safety of existing fluid streams, minimize reliance on additives, and improve product processing times.

What Is Trupor® Membrane Microfiltration Filter Media?

Backed by two centuries of expertise in fibrous porous materials, Hollingsworth & Vose (H&V) developed Trupor®, our first microfiltration membrane product. Customers in the food and beverage and bioprocessing industries particularly benefit from Trupor®’s reliability, performance, and thinnest possible efficiency layer. Its superior pore size uniformity and composite design provides stable performance over a long operating life.

H&V sells Trupor® as a rolled good, and customers can convert it into liquid filtration cartridges for uses across different industries.

Trupor® Filter Media Applications

Trupor® filter media has applications in many industries, such as:

Food and Beverage

The food and beverage industry demands innovative products and solutions to meet strict industry standards and high customer expectations. Trupor® is one such product, as its higher flow rates offer significant benefits: longer shelf life, increased yields, and lower production costs.


Products made by microbes must be filtered and treated properly. Once products are ready to be harvested, Trupor® filter media provides high flow rates and shorter dwell times. Our filter media’s high flux and long life minimize energy costs, which reduces the cost of process water and buffer fluids while maintaining safety and quality standards.


Trupor®’s chemical stability and enhanced performance make it ideal in the industrial sector for processes such as:

  • Electroplating
  • Ink and dye production
  • Chemical mechanical polishing (CMP)

Water Reuse

Trupor® is available in widths of up to 40 inches (100 cm), expanding the available form factors of microfiltration. The membrane’s high flux enhances water filtration efficiency, and integrating it into existing filtration trains can result in lower operational costs. Trupor® filter media can also protect downstream reverse osmosis (RO), ultrafiltration (UF), and nanofiltration (NF) processes from finer pollutants.

Trupor® Filter Media Benefits

Trupor® offers more benefits compared to conventional high-performance membranes. These include: 

  • Best-in-Class Flow Rates: Trupor® offers best-in-class flow rates, outperforming many traditional membrane materials. 
  • Lower Costs: Trupor® is designed with cost-effectiveness in mind. Unlike other high-performance membrane cartridges, which are manufactured in bonded 10″-length segments, Trupor® is available in wider rolls of up to 40″ in width, enabling the production of continuous-length pleated cartridges without the need for modular construction. This reduces the cost of raw materials and assembly labor, making Trupor® more cost-effective.  
  • Improved Efficiency: Trupor®’s higher flux allows for faster filtration rates, saving energy costs and enhancing the overall efficiency of water treatment and other filtration processes.
  • Thinnest Possible Efficiency Layer: Trupor® boasts the thinnest possible efficiency layer and uniform pore sizes, allowing for high-efficiency filtration.

Trupor® Filter Media: Solution for Industrial Pleated Filter and Cartridge Manufacturers

H&V’s 200+ years of innovation in porous materials led to the creation of Trupor®, an improved microfiltration membrane. Available in roll widths up to 40”, Trupor® is well-suited for the production of continuous-length pleated cartridges without the quality risks and extra costs that come with modular construction. Trupor® is also ideal for “high flow” pleated cartridges with outer diameters ranging from 6” to 8” and lengths of 20” to 40”. Our filter media provides better flux compared to cast membranes in pleated and flat sheet elements.

Choose Trupor® Filter Media

H&V’s Trupor® filter media can be easily processed with standard pleating and production equipment. It can be co-pleated with other materials to extend the filter’s lifespan and minimize change-outs, or it can serve as a final efficiency layer to enhance flow rates. Trupor® is reliable, durable, and cost-effective, delivering exceptional filtration performance. Its excellent pore size uniformity and composite structure offer stable long-term performance with the thinnest possible efficiency layer.
