Its snug fit prevents accidental dislodging, effectively blocks up to 99% of paint mist and dust, and extends the life of your costly filters. Compatible with 3M 6000 series cartridges and various filter types, it’s a must-have for professionals demanding reliable respiratory protection. ## Description 3M 501 Filter Retainer Lot of 2 Review: Best Fit - There are many imitators, but the 3M brand is the one that fits the best. It is actually probably a little “over snug” in fit — it can be a little difficult to put on, and a even more difficult to remove. I have four non-3M brand covers that came as part of a mask and filter cartridge packages which I use for non-critical filter situations. Only one of those covers stays on, the other 3 sets fall off if bumped — not good if your pre-filter drops in dirt, dust, sawdust, paint, etc. When it matters, stick with the 3M brand covers and filters. No, I don’t work for 3M, but I do trust their products the most. :) Review: Worth their weight in gold - I love these, and I’m so glad I found them. I do a lot of spray painting, and ruining expensive cartridges was getting expensive. I found that I can pair these with a set of 3M part number 603's and 3M 5P71 or 5N11 cotton filters, and they still block 99% of the paint. I say 99% because I don't believe any paint mist comes through. But I didn't do any scientific tests… I’m primarily using the “painted nostril hair” test. If you had any doubts, you could probably stuff two cotton filters in there. If you’ve got an oil based paint or something more dangerous, they also fit over regular 3M 6000 series cartridges. So this would be a pre-filter over your expensive filters to keep paint and dust from clogging them up and make them last longer. A great little accessory. Hope some of this helps! ## Features - 3M 051138176686 ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | 3M | | Color | White | | Item Dimensions | 4 x 1 x 4 inches | | Item dimensions L x W x H | 4 x 1 x 4 inches | | Material | Plastic | | Material Type | Plastic | | Model Name | 3M - 501 - 2pk | | Number of Layers | 2 | | Size | Pack of 2 | | Unit Count | 1 Count | ## Product Details - **Brand:** 3M - **Color:** White - **Material:** Plastic - **Model Name:** 3M - 501 - 2pk - **Size:** Pack of 2 ## Images ![501 Filter Retainer Lot of 2 - Image 1](https://m.media-amazon.com/images/I/41CNwWKbOzL.jpg) ## Questions & Answers **Q: How often do you have to change the retainer ?** A: The retainer never needs replacing unless you crack or break it. It is a plastic cap that fits on top of 3M 6000 series cartridges or 5000 series respirators to hold 3M particulate filters 5N11 or 5P71. This allows you to replace your particulate filters without having to replace the entire cartridge. **Q: When this is all combined with the adapter and filters will there be something for the hole? I've seen some pictures where there appears to be plug** A: The hole is filled by the n95 filter pad that fits tightly within the adapter. The pads can be used for days or even weeks between changes, although care must be taken that the outside surface of the pad is not touched during changes. The hole should only have the outside surface of the pad showing. Make sure that the writing side of the pad is toward the inside. **Q: Para que sirve esto?** A: Son las tapas qué sujetan los filtros de tela que van encima de los cartuchos. **Q: Will it fit 3m multi gas/vapor cartridge/filter 60926,** A: Yes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Fit *by N***R on December 7, 2022* There are many imitators, but the 3M brand is the one that fits the best.
