Adding $50+/person in Covid protection monthly can force people to have to choose between food or Covid protections. In addition in times of shortages, people have no choice but to reuse masks, so knowing how to do it in the safest possible way is very important.</div><div class=""><br class=""></div><div class="">I am glad that CDC and others are looking into safe ways of reusing masks. Besides the financial impact on families, the disposal of all of these masks presents a real environmental problem. So there are lots of good reasons to look for ways to reuse masks. </div><div class=""><br class=""></div><div class="">Due to my illness I have been wearing N95 masks every time I leave the house (and in 2014-15 around the clock). I have devised a system of reusing the masks where I usually need 5 masks for 12-15 days. My system is very similar (probably more conservative) than the one described in the article. But I have not become sick in spite of frequent visits to medical offices, so clearly reusing masks works for me. I expect that each of us has enough sense to not reuse a mask full of sweat and other gross stuff, but most of us do not fill our masks with sweat very often.</div><div class=""><br class=""></div><div class="">Hope I can make you aware of other perspectives on mask reuse.</div><div class=""><br class=""></div><div class="">Stay well,</div><div class="">Olga</div><div class=""><br class=""></div><div class=""><div><br class=""><blockquote class="" type="cite"><div class="">On Jan 19, 2022, at 8:03 PM, Robert Primak <<a class="" href="mailto:bobprimak@yahoo.com">bobprimak@yahoo.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class=""><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;" class="ydpa15a9414yahoo-style-wrap"><div class=""></div>
<div class="" data-setdir="false" dir="ltr">Actually, it's more like three days max.

After that time, they get pretty gross on the inside. This includes about 90 mins per day of significant exercise, or physical volunteer work for about two to three hours per day. Only about a day in summertime hot, humid weather, or if rain or snow have gotten onto the outside of the mask. Dusty environments can use up an N95 mask even quicker. </div><div class="" data-setdir="false" dir="ltr"><br class=""></div><div class="" data-setdir="false" dir="ltr">All of this said, N95 masks are about the only protection we can have against the unmasked people who put the "gross" into grocery shopping.
