"I know what the positive pressure masks are for or can help with. My point was that they are quite expensive comparatively. "

I've seen less expensive ones. The link was simply to the first example of the tech I found, and was for illustrative purposes only.

But the point is that only a tiny minority would ever need a PP mask. Most can do quite well with a non-PP mask. And on my wife's last grocery shopping trip, our local HEB store had, IN STOCK, both disposable and reusable masks, so apparently AMERICAN production has caught up with the lag.

None of our big box stores have them and I would certainly like to have them for painting and woodworking, etc... Most of the disposable dust masks are woefully inadequate for preventing dust entering the airway.

I just want a damned respirator and some cartridges for regular home maintenance and I can’t get them because everyone is still in panic mode and doesn’t understand what they really need.
