## 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.

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. :)
