Why are there so many different mask types and styles? Which ones work best? How will I know which one to use? Which one is the "safest" for me to wear?
These are all great questions, and ones I hear quite often.
I must preface this by saying that I am not a doctor nor am I an epidemiologist or a health professional, and I DO NOT dispense medical advice. Where I quote statistics or scientific facts I will annotate with a hyperlink to my data.
These suggestions and explanations are from my own research and experience. This is MY OPINION and what I do for my own family.
As always, do your research, investigate and seek out multiple sources to decide what works best for you and your family. I guess
I can answer these questions with a question of my own... "Why are there so many different styles and types of footwear?" In other words, why do you own so many different pairs of shoes? They cover your feet, right? Why isn't one pair enough?
