If your worried about ebola, I suggest full face respirators (100-200$). n95 is good, (they say 95%). But a p100 and full face respirator is the next best thing to external air supply or re breathers, as far as I am aware.
And its very wise to keep your preps to yourself. Even on the web. I think You are in good company here for chit chat on the subject, this community is relatively small.
*edit splurge for a fitting test on the full face mask, it will open your eyes in regards to n95 and or any mask that is not sealed to your skin.
Never be afraid to do the righteous thing, nothing righteous is ever easy.
