Do dust mask filters have a standard bayonet fitting

[Bryan Field]

I have a MSA half mask I wear when using CA glue. Does any one know if the filters that fit other masks will fit this? As far as I can tell MSA doesn't make a plain dust filter, which is what I would prefer to use when sanding. Is the bayonet fitting standard across al mask manufacturers?

So far every mask I have bought has had it own style of attaching the filters, some of the diameters are close but actually never fit its PITA

I don't know the mask and filters you are referring to, but would it be possible to get someone to 3D print an adapter?

In my experience, once you’re on a brand, say 3M vs. Honeywell/North vs. Sundstrom, that brand uniquely defines the filter physical interface. That said, doing a little searching around I was able to find third-party P100 filters, for example, for North system masks. The main problem with those is vetting them for actual filtration quality, since they tend to be from random sellers from China on Amazon rather than known-quantity filter makers.

So in short: there are no cross-brand standards for these filters.
