ErtelAlsop Micro-Media filter sheets are composed of cellulose pulp, Diatomaceous Earth and/or Perlite and a wet strength resin, which charge modifies the media to exhibit a net positive charge zeta potential. This allows for the highly efficient removal of particles smaller than the filter’s nominal rating.

Micro-Media Series Depth Filter Media, formulated with cellulose, wet strength resin and diatomite and/or perlite is specifically designed for use in critical applications. All components of ErtelAlsop Micro-Media are listed in the CFR as generally recognized as safe for contact with food as dictated by 21CFR 176.170.
