Bests & Worsts Reviews from Amazon

Here is how I evaluate the mask... #1. Does any authority such as the FDA tested it to see if it lives up to what it says it will do? In this case yes its on the FDA list for KN95 respirators. #2, When I hold the mask up to the light can I see the light bulb or light source? If there is any spacing where I can actually see the bulb its not a good filter. This passed that test. #3. When I breath through the mask is the mask itself sucking in to my mouth? If so then its a very good seal to my face. This passed that test. Keep in mind this mask is designed for one-time single use meaning at the end of a shift you are to throw it away. However, I know many people wont be doing that therefore to keep it sanitized place it on foil and put in over for 30 minutes at 170 degrees. Then at the end to be sure quarantine that mask for 4 to 7 days. There is a trick of getting 7 brown paper bags...paper so moisture will be able to flow out for mildew concerns...label each bag Monday, Tuesday, Weds...etc...put one mask in each bag and when done for the day with the mask place in oven at 170 degrees for 30 minutes. That will get rid of any moisture, kill germs/virus and set it up for quarantine. If you have a large face like I do then this will fit very well. For smaller faces I suggest the Powecom KN95 mask at Officedepot. The Powecom is on the FDA approved list. I know this thing seems like flimsy paper mask but the actual material matters. A scarf is thick and it seems like thats the better filter but its not. This mask is an actual filtration medium and it will work very well. I do have a geniune 3M N95 mask here to compare this one with and the 3M is just as flimsy as this one. In short, you can trust this mask. I do highly suggest getting the cheaper surgical style mask and placing that over the KN95 mask
