3M Filter cover 501

Replaceable filter covers. People used to think that offices in fancy buildings and thousands of employees in black suits were enough. But that's not true, because many companies produce other, no less important products in factories. Such places are dangerous because everyone should take care of their personal safety and integrate protective equipment into their work. Face masks are very important in dusty places. Most face masks are durable and reusable, but require frequent maintenance. Certain parts such as filters or covers are crucial. These 3M filter covers are one of the best on the market. They can be combined with the 5000 series particle filter inserts and with the gas and vapour filters and can therefore be used with various mask models.
