Process Water for Food & Beverage

Our filters are used in Food & Beverage for water treatment applications such as removing sediment from simple wash/rinse water to assuring the efficient operation of particle removal, bacteria reduction/removal, tank filtration and sterilization.


Ultrapure Water for Electronics/Semiconductor

Critical Process Filtration products help operations meet stringent water purity standards through ultrafine particle removal, bacteria control and vent filtration.


Currently installed in healthcare facilities, our filters ultimately protect patients from bacteria and other organisms. A variety of filters are used for medical device reprocessing and in water treatment systems that supply water for functions from wound cleaning to hemodialysis. 


Industrial Process Water Systems

Filters are used in industrial systems to remove particles that harm industrial process efficiency or final product quality. The higher the required water quality, the more filtration options we provide.


Don't go it alone. Our technical experts can help you find a solution among so many choices and variables.

When filtration performance isn't meeting expectations, or you're developing a new process and a fresh perspective is needed, you can count on us to help troubleshoot and configure the best-fit solution for your operation.

Quality Assurance and Standards

Critical Process Filtration filters are designed for use in cGMP compliant processes. Our state-of-the-art manufacturing facility and quality-management system both meet ISO 9001:2015 standards. Each operation from assembly and test to cleaning, drying, and packaging is done in appropriately rated clean rooms, and each filter is assigned a lot code to ensure the traceability of manufacturing data and materials. A sophisticated MRP system collects and processes real-time data from manufacturing centers and inspection points. 

USP Biosafety and FDA Compliance

The materials used to construct pharmaceutical-grade filters are non-toxic and meet the requirements for the MEM Elution Cytotoxicity Test and the requirements for Biological Reactivity Tests in the current version of the United States Pharmacopeia (USP) for Class VI - 121 °C Plastics. Critical Process Filtration filters comply with Title 21 CFR sections 210.3 (b)(6) and 211.72, for non-fiber-releasing filters. The levels of bacterial endotoxins in aqueous extracts from pharmaceutical-grade filters are below current USP limits as specified for water for injection.
