N, R, P 95 99 100

I am just gonna drop this here as a reference guide to people who are confounded by letters and numbers.

N series masks (N – NOT oil resistant)

R series masks (Resists oil)

P series masks (oil “Proof”)

That’s what the letters are about, and that’s all they are about – their ability to filter out oil based contaminates in the air.

95 series masks – removes 95% of particles 0.3 microns or larger

99 series masks – removes 99% of particles 0.3 microns or larger

100 series masks – removes 99.97% of particles 0.3 microns or larger (This is HEPA level filtration)

Right now, N-95 masks are probably on back order at your local drug store due to the Chinese War Virus of 2020. Keep in mind that masks are used by industries other than Health Care, and masks can be found in some places that may not occur to you at first blush. Also keep in mind that N-95 masks are the minimum recommended effective face mask. The 99s and 100s, the R series and P series will all work as well as an N-95, albeit at a slightly higher price.

Wash your hands and keep them away from your face. Old advice, but it’s still true.

  1. I say corona, you say ebola.

    You say mask, I say “quit breathing on me!”

    You say “wash your hands”, I say “Stop touching me!”

  2. When I sit here thinking about it
    I began to pee in my panties
    I then broke wind
    And felt it a sin.

    I think I may order chineeese take out.

  3. I found some 3M auto paint masks (P95s) for under 25 dollar on NewEgg of all places.

    These are full lower face masks of the type I used to wear when I was engaging in serious creation of wood dust and/or spraying of stains or paint. They are more obtrusive than the medical style masks, but they actually do seal your air holes from breathing in VOCs and such.


    I used to wear these for hours at the time; you get used to them pretty quickly.

  4. Dear Sirs,

    I must object to your lack of spam in this post. Spam is at the center of my life, and by reading your dribble and not finding any spam within, I feel as if I have wasted my valuable time. I wish to object in the strongest possible terms.

    Yours in spam,

  5. Long ago, I used to pick spam from the lovely spam trees that grew near the fence of the prison I lived in. I still have a taste for spam, even after the electrshock treatments.

    I guess I’m just a spam lover for life.
