      Why don't they put a warning that vented masks may protect the wearer but they still SPREAD covid through the vent and need another mask over it??

      Answer This Question

      They will prevent the spread better than someone that can spit through a cloth mask. The CDC wants to reduce the ability for large droplets (aka moist talking) with the use of masks. This will do that better than most masks. See here https://multimedia.3m.com/mws/media/1994317O/understanding-valved-respirators-united-states-faq.pdf

        NIOSH has approved the 3M 8511 mask for Covid-19 and the CDC website specifically says masks with a front valve do provide two way protection. It's in the FAQs. https://www.cdc.gov/coronavirus/2019-ncov/hcp/respirator-use-faq.html

              The respirators I received have a very strong smell. Is this normal for these (preservative or fumigant of some sort) or did I get sent counterfeits?

                          These masks are a must for any sanding project! I feel protected, but they can be a bit tight. Not the most comfortable to wear, but a necessary evil to keep crap out of my lungs.

                            They worked great for what we needed the masks for, we were stamping concrete with antique/ release agent that is a fine dust and also can cause damage or be canceress, protection was great. Only downside was it was difficult to breathe

                            The 3m cup mask design is very durable and effective. I use it for all kinds of tasks where dust, dirt or mold are blown about. I like the exhale port on the mask since this greatly extends the filter life. I highly recommend it for and dust environment or fiberglass insulation install job. For extra life try gently prestretching the head bands. Store mask in a zip lock bag between uses.
