Filter Paper

Filter Paper


At Pure Process we supply ErtelAlsop's selection of filter paper for use in many applications in the food, beverage, chemical, pharmaceutical, and cosmetic industries.

Our partners, ErtelAlsop, offer the widest variety of high quality specialty filter paper available. From laboratory to full-scale production, we can supply the best product for your liquid filtration application. We can now also offer Pharmaceutical Grade Filter Paper, specifically for use in critical applications.

For many years filter paper has been widely accepted as one of the most versatile filter media available. Due to a basic formulation of cellulose fibers with or without wet strength resins, it is highly compatible and can be used for a wide range of applications. Filter paper provides a more economical solution for those applications requiring low solids retention or cake building.

Micro-Media® P-Grade Filter Paper is composed of cellulose pulp with all virgin raw materials and RO water and with or without wet strength resin. Each batch is lot numbered, allowing for lot-to-lot traceability and batch-to-batch consistency. Current available P-grades include 6095P, 6392P, 6492P, 7133P, 7265P, 7362P 7762P, 8393P and 9363P. Please Contact Us directly for the availablity of other grades.

Each shipment contains a Certificate of Compliance as well as an ErtelAlsop P-Certificate, stating that the batch of material, used to produce the order, was manufactured in accordance with the ErtelAlsop Validation Guide for Pharmaceutical Grade Filter Paper (Bulletin VG-P-2/03) and meets the quality standards outlined in that document.

When compared to standard grades of paper, Micro-Media® Pharmaceutical Grade Filter Paper provides superior quality, lower extractable levels, and greater consistency.

Filter Paper is used in the food and beverage, chemical, and pharmaceutical industries for clarifying or as a septum to hold cakes of diatomaceous earth, activated carbon, perlite, powdered cellulose, or other filter aids in plate and frame filter presses, horizontal plate filters, and Nutsch filters. In blood fractionation, filter paper is used to collect paste in plate and frame filter presses. Filter paper is also used for the filtration of cosmetics, flavors, fragrances, and personal care products with low levels of particulate.

Through ErtelAlsop we can now provide you with the best combination of filtration equipment and filter media to meet your specific needs, whether it is filter pads or filter paper.
