Description
3M 501 Filter Retainer - Keeps Your Particulate Filters Securely in Place
The 3M 501 Filter Retainer is an accessory that holds 3M particulate filters at the front of a respirator so they stay correctly seated in use.

FAQ
What does the 3M 501 Filter Retainer do?
It keeps 3M Filters 5911, 5925 and 5935 in place at the front of the respirator, so the filter stays correctly seated against the cartridge while you work.
Which 3M filters and cartridges is it compatible with?
It is for use with 3M Particulate Filters 5000 Series and 3M Cartridges 6000 Series.
Does the retainer include filters or a mask?
No. The 501 is a retainer only. The respirator mask, cartridges and filters are sold separately.
Can I add particulate protection to gas and vapour filters?
Yes. Used with 3M Filters 5000 Series, the retainer allows particulate protection to be added to gas and vapour filters.
Why would I use this on a yard?
Stable work creates a lot of airborne dust - sweeping, mucking out, shaking up shavings or straw, handling hay and mixing powdered feeds or supplements. The retainer keeps the particulate filter properly positioned through those jobs.
How do I look after it?
Wipe it clean after use and store it dry and away from dust. Replace filters in line with the instructions supplied with them, and always follow 3M's fitting guidance for your respirator.
