Museum display cases are intended to protect and preserve art and cultural assets not only from theft and vandalism, but also from exhibit-damaging influences.

Emissions in display cases and exhibition rooms and the resulting pollutant loads on exhibits are therefore a perennial topic. Emission measurements are often not carried out at all or are not repeated on a regular basis. The total concentration of emissions/pollutants in a display case is then not known. This leads time and again, and especially in the long term, to damage to valuable cultural objects as well as to display case glazing (due to fogging and crizzling).

Remedy can be created by the use of REIERs newly developed filter devices, which can be equipped with suitable sorbents (non-toxic) against pollutants brought in from the outside and created indoors.

Depending on the selection, the sorbents ensure broad adsorption, absorption and also chemical binding of harmful gases.

The newly developed filterbox is easy and uncomplicated to handle and enables the air in the display case to be filtered of pollutants in both, new and existing display cases, and protects exhibits from damaging influences.
