Pretty much everything from light use to industrial-strength models when I was last there.

You can get them at just about any pharmacy, the issue you have to address is the quality, the mask need to be N95 approved or most of the small particles will pass though it, for a decent 3M it will start from about 40t. Its still not perfect but the best easily available local option
