Review on 🛡️ Highly Reliable 3M 8511PB1 Particulate Respirator 10 Pack: Optimal Protection and Quality Assurance by Robert Espinoza

This face mask is listed on the US Centers for Disease Control and Prevention (CDC) website as one of their recommended N95 face filter respirators. This differs from a surgical mask as it filters out smaller particles. I cannot stress enough the importance of a good mask seal. These masks come in a variety of styles and shapes. Finding one that fits your face is important. Whether a mask really fits your face can only be determined by a tight fit test. Aptitude test kits can be purchased online. I don't know how accurate they are. I highly recommend performing a fit test if the purpose of the mask is to protect against biological particles. I am a nurse. Through fitting testing, I found that the type of mask I was using did not fit. It doesn't offer a perfect fit. You can't put on a mask and say you have a seal. I found my mask perfect. I could feel it touching the edges of my face, but tests showed I didn't have a 100% seal. When using a mask to shield 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 instructions before use as there is a great risk of getting infected with the mask if you don't know how to use it.
