Consulting the Silver Expert

A New Addition to Your Silver-care Arsenal

The Intercept’s Portable Filtration Unit is a small battery-operated device that uses a non-woven copper filter that absorbs and neutralizes atmospheric pollution (including ozone, nitrous groups, sulfur compounds, chlorine compounds, gaseous acetic acid, and more) in silver cabinets.

The passive cleaning and active air filtration within those cabinets leaves a pristine environment with silver free of tarnish.

If the silver exists in a humid environment, use silica gel to absorb the moisture.

The filter does not outgas, so nothing will coat the items. Cabinets need not be 100% sealed for the unit to function properly.

It will filter one full air exchange per hour per cubic meter of display continuously for 90 days (more or less depending on how polluted the interior environment is) before the fully saturated copper filter must be changed (when the filter turns grey).
