Abstract: A respiratory filter includes an air-permeable sleeve and at least one filter layer that is arranged in the sleeve and contains activated carbon. The activated carbon contained in the filter layers serves as a gas filter that, by absorption, at least partially removes the noxious gases that are contained in the air inhaled.

Abstract: A cleaning device includes a hollow body provided with at least one flat cleaning surface and at least one outlet and filling opening. The hollow body is filled with a cleaning agent or disinfectant. An absorbent cleaning material is detachably secured to the hollow body. The absorbent material includes a cleaning pad which can be separated in one piece from the hollow body.

Abstract: The invention concerns a device for cleaning flat objects, in particular sterile areas in hospitals, laboratories and doctors' practices, the cleaning device comprising a hollow body which is provided with at least one flat cleaning surface and at least one outlet and filling opening, is filled with a cleaning agent or disinfectant and on which an absorbent cleaning material is detachably secured. According to the invention, in order to ensure that dirt and germs are reliably removed from the flat objects to be cleaned and germs are prevented from spreading to sterile regions in hospitals, laboratories and doctors' practices, the absorbent cleaning material consists of a cleaning pad (3) which can be separated in one piece from the hollow body. In advantageous developments of the invention, the cleaning pad consists of a stable resistant woven cloth made of natural or synthetic fibers and comprises surfaces made of rough scouring cloth or a soft wiping cloth.

Abstract: The invention concerns a pressure-deformable wiper cushion for wiping misted and/or dirty in particular flat surfaces such as the insides of vehicle windows. The cushion has a bag-shaped cleaning cover the outside of which during wiping comes into contact with the surface being cleaned; and a cushion filling enclosed by and filling out the cleaning cover on the inside. As a way of significantly improving the wiping effect even on dry surfaces, while maintaining ease of use, it is proposed that a container should take the place of part of the cushion filling in the cushion interior and should comprise a reservoir section and a closable neck, and that a mechanically operated spray head should be incorporated in the neck and fitted with a spray nozzle outside the cover.

Abstract: The invention refers to a disposable dust-cloth. The cloth is part of a dry natural fiber material that is a soft open-pored puffy pulp paper, in colors ranging from light to white, with a filler fraction of less than 10%. The paper is impregnated with a biodegradable wax which has a hardness that prevents its shearing off from the natural fiber material. The wax is a natural wax of plant or animal origin, preferably carnauba or bees waxes, or a synthetic or a chemically modified wax, preferably a paraffin, oxidized polyethylene wax or hydrogenized jojoba oil.
