Renewal 3M 501 Filter Retainer Cover for Particulate Filter 5N11 for 6000 and 7000 respirators (501 Retainer, 20, Count)

Its a shame I had to buy these as they where not included in a 3M filter package I previously purchased for my mask.

Perfect replacment for my 3m mask. Fit is good and works well. Very happy with purchase.The plastic is a little more rigid than the OEM that came with the mask.

These are Standard respirator covers. They work exactly as prescribed and work well. Add your chemical filter on the respirator, then add the dust /mist pad with lettering towards the mask and snap these covers to hold them on. Once on they hold tight. Good value

I have used 3M filters/products professionally and know they are dependable and work as advertised. I know I can depend on them for use in my shop as well.

Good quality !

In general, 3M makes reliable products, though they are sometimes overpriced. But when it comes to respirators, there simply is no other brand that competes. And, how do you put a price on your ability to breath well? I have watched people die of lung corruption. WEAR a MASK!

I'm not really sure what to make of these. The ones I've gotten from 3M in the past were clear, and the ones on the 3M website still appear to be clear. Did 3M make a new, opaque version? I'm not sure. This listing says "Brand: Beejong" and " Manufacturer ‏ : ‎ 3M_safe ". If these are really 3M the brand **should** say "Brand: 3M" and the manufacturer should say " Manufacturer ‏ : ‎ 3M", but it doesn't.So, these seem to seal ok, to hold the pre-filters on to gas filters, but the listing is weird and I'm not really liking that the covers are opaque.

I could not find any indication that 3M makes these in gray, despite the listing, images, and product itself bearing the 3M logo. I'd give it 5 stars if not for that. I think I'd find it more trustworthy if no attempt was made to indicate that this was an official product.The retainers themselves work well. They fit exactly like my official 3M ones do and they look and feel pretty much the same aside from the color. I have a half and a full mask respirator and one of them already has filter retainers but the other does not, so these will be nice for that.However, at the time of writing, it is actually cheaper to get the official 3M brand filter retainer than to get this product.
