Storage Instructions 

VK-530 filters should be stored at 2°C (35.6°F) to 55°C (131°F), with humidity lower than 80%, away from any significant sources of vibration. They should be protected from solar radiation, oxidant agents, shocks, and anything that could make the filters fall down. Do not allow filters to come into contact with ketones, esters, hydrocarbons, acids and strong bases, high pressure fluids, and liquids.

Each NBC-77 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at an even temperature, ideally at -5 to +30°C, with relative humidity below 80%. Sealed filters also tolerate conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.
