THIS IS NOT A BANDANA
Q: I work at the hospital in Helena. We are using the material surgical tools are wrapped in for facemasks. Is that ok? A. Nurse 4/6/2020
A: Facemasks are not like standard cloth. The are scientifically engineered to protect from specific hazards.
Q: Isn't a filter a filter? Isn't a dishcloth better than nothing?
A: A spaghetti strainer is a filter, but it can't pass the "pressure drop" test standards (and neither can a dish towel or t-shirt). There is no standard for "better than nothing"...which is usually said right before "Hey, watch this!"
Q: If I hold fabric up to the light and can't see sunlight is that good enough?
A: A virus is a fraction of the size of a red blood cell. Facemasks must pass FDA regulated testing to ensure your safety. I assure you it does not include "holding it up to the light"! Are you willing to trust it with the life of you and your loved ones?
Q: Is KN95 safe to use?
A: The FDA approved KN95 for use on April 3, 2020. As long as the product is manufactured correctly, the cerficates are authentic it should be acceptable. Not all masks are made correctly!
Q: In N95 the best?
A: It is thought be adequate, but 99.9 aka 100 may better. Q: What is the difference between a mask and a respirator?
A: Masks are loose and protect others from your spray. Respirators are two way, protecting both people.
