Cartridges are simply twisted on or off the facepiece for easy replacement, allowing the easily cleaned facepiece to be reused.

All 3M Facepiece Respirators can be used with ANY of 3M's vapor cartridges and pre-filter combinations. The simple white, oblong pre-filters are held on to the cartridge with a 501 adapter. All round pre-filters, when used on a vapor cartridge, attach to a 502 adapter. All round pre-filters can also attach directly to a facepiece when only particulate (NOT vapor) protection is required
