3M™ Filter Retainer 501

3M 501 are original filter retainers engineered to securely snap and hold 3M 5000 series particulate pre-filters (such as 5911, 5925, and 5935) directly onto 3M 6000 series gas and vapor cartridges. By using the 3M 501 retainer caps, users create a modular dual-protection system that simultaneously filters out airborne particulates, paint spray mists, and organic gas/solvent vapors. This makes them an essential safety component in body shops, spray booths, and industrial refinish environments.

Molded from durable, lightweight plastic, these retainers allow quick pre-filter inspection and replacement whenever clogged. The price is for one pack containing 2 retainer caps (1 pair).

Key Features & Benefits:

• Secure Snap-On Fit: Clips firmly over 3M gas cartridges, locking particulate pre-filters evenly in place.
• Dual Protection Setup: Enables combining particulate pre-filters (5911/5925/5935) with organic vapor cartridges (6051/6055/6059).

• Pack of 2: Convenient pair packaging ready for complete respirator setup.
