I have never been so concerned about air quality both in my house and in public places.
I have gone well out of my way just to make sure I have borderline HEPA quality masks to wear whenever I leave my house.
Of course I do it in part to protect others’ safety, but first and foremost I do it to protect myself. I have asthma and lung allergies, I really can’t afford to get sick with this virus. Even if I had a perfect medical history, it’s a process of rolling the dice with long term side effects. This is regardless of whether or not I end up with a severe case. When I take stock of my fear and formulate my plans for where to find my groceries each week, I try my best to avoid going into cramped buildings with lots of people. Many do not realize the proximity effect, and how viral particles have less air to disperse in whenever you shrink the size of the indoor space. Huge stores like Walmart have HVAC systems churning through a massive amount of oxygen and carbon dioxide while shoppers are relegated to the ground and a few feet above it. I can’t even imagine going into a restaurant, especially one with no windows and packed seating. It doesn’t matter if their air conditioner has a HEPA filter in it or not, the viral particle exposure is exponentially worse in tight and close proximity to others compared to shopping in a grocery store with vaulted ceilings. You’d literally have to offer to pay me, and even then I probably wouldn’t eat at a restaurant. This is the case even if I’m wearing a gas mask or a full face shield over a small N95 mask. I do not want to put my life at risk over something as trivial as eating in public.
