Bests & Worsts Reviews from Amazon

This facemask is on the CDC website as one of the N95 particulate filtering facepiece respirators that they recommend. This is different than a surgical mask as it filters smaller particles. I can not stress enough how important a good seal is with the mask.These masks come in a wide variety of styles and shapes. It is important to find one that fits your face. The only way to know if the mask truly fits your face is with a fit test. Fit test kits can be purchased online. I do not know how accurate they are. I highly recommend a fit test if the purpose of the mask is to protect you from biological particles. I am a nurse. It was through fit testing that I discovered the type of mask I was using did not fit .It was not making a perfect seal. You can not put the mask on and say you have a seal. I thought that my mask was a perfect fit. I could feel it touching the sides of my face, yet fit testing determined I did not have a 100% seal. If you use the mask to screen biological particles it is important not to touch the outside of the mask. You can infect yourself. The exhalation valve on the mask prevents moisture build up and makes exhalation easier. Read the directions before using as there is a great risk of contaminating yourself with the mask if you don't know how to use it.
