Respirator Filters

[SMALMALEKI]

Hi wood working community

we all know harmful wood dust could be? Today at work I was given JSP P3 mask respirator.
The same masks are available from hardware stores and online.
does anybody know what the difference is between P3RD and P3R filters?

Thank you Droogs

I was thinking of P3 Respiratory toru and dust. Disposable seems good as well.
