3M Mask with 2135 P2/P3 Filter Enough for MDF?

[andycorleone]

Hi, I have a 3M 6300 Mask an use 2135 Filters which are rated P2/P3 Particulate, I normally change them every month. But are they Enough for MDF? I have been feeling maybe no :?:

Hi Andy,

Most masks (at least the ones worth having) offer P2 but P3 is better. I seem to remember reading somewhere that P2 gives around 40 times more protection than your natural nasal filters, ie your nose hairs! So P2 is fine but if you're worried go for the P3.
