@merpreb My husband found these at a hardware store. It fits very tightly and I put a cloth mask over it.

Thank you, Becky @becsbuddy. I just finished the message below and saw yours....placed an order! They're on the way. I bet you they'll soon be out! Aren't you a doll!
Blessings.

Hi Becky! This is might be for carpentry uses. Just make sure that there if people are going to buy N95 masks from a hardware store or similar, they make sure there is no "valve" in them because many stores do put them on display as "N95 Masks in stock now". Check to make sure that they say NIOSH approved because MANY of the N95 and KN95 masks for sale right now are not. This means either no testing was done, or worse yet, they failed I believe. The 3M 142-8210 plus N95 is for diseases. I'm not sure if the carpentry mask will work, despite the fact that it traps fine particles. Sanding and human droplets may need 2 different filters.

Becky - Tell your husband "Good Find!" Thank you for the image. It shows exactly what I was talking about yesterday - this mask is made correctly, with the straps "welded" to the flange so they don't pierce the protective layers. I looked it up and it is NIOSH approved and meets FDA surgical respirator standards - see my remark below.

All N95 masks are all made to the same standard. The difference between "industrial" respirators and medical ones is the breathing valve in most industrial masks, making them easier to breathe in. Unfortunately, the valve can let infectious droplets out. NIOSH approval is the key - it means more than one sample has been tested by an independent lab and complies with the standards.

HOW TO TELL IF AN SPECIFIC N95 MASK IS NIOSH APPROVED:
Here is a link to a list of NIOSH approved masks: https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/N95list1sect2-m.html
The list is very long, but at the bottom of the first page is an alphabet so you can skip to what you want. Pay attention to the exact model number.

PS I hate wearing N95 masks without a valve, but I do it. I use the valved ones in the yard and around dust.
