ErtelAlsop has been an innovator in the manufacturing of depth filter media and liquid filtration machinery since the 1920’s. Their uniquely flexible products and services enable process and product efficiencies for a broad spectrum of customers in Life Sciences, Food and Beverage, and Industrial markets.

MicroMedia DE depth filter sheets span the entire range of removal needs in the food and beverage industry and are specifically designed for use in critical applications. These sheets are 400mm x 400mm square and come in grades for microbial reduction as well as fine, clarifying, and coarse filtration of liquids. They also feature high solids loading capacity.

ErtelAlsop MicroMedia DE depth filter sheets are composed of cellulose pulp, diatomaceous earth, and a wet strength resin. This resin gives the media a net positive charge (called zeta potential), which allows for the highly efficient removal of particles smaller than the filter’s nominal rating. Wet strength resins are also steam sterilizable and are free of formaldehyde.

All components of ErtelAlsop MicroMedia depth filter sheets are listed in the CFR as generally recognized as safe for contact with food as dictated by 21 CFR 176.170. These sheets also meet USDA Subpart G – 205.605 & 205.606 standards for contact with food labeled as organic.

ErtelAlsop depth filter sheets are an excellent alternative to Pall depth filter sheets, as well as Eaton BECO and BECOPAD depth filter sheets. Please contact us to consult about the equivalent replacement for your current Pall or Eaton BECO filter sheets.
