I only have 2 masks, both homemade. (Don't get out much!) The one I like best is the simplest of these:?
?
- no nose wire. Outer layer is quilting cotton, inner layer just cotton muslin, with a long tie cut from jersey instead of ear loops. I can wear it comfortably in hot weather for an hourlong walk.
More importantly - not sure stressing about percentage effectiveness is that useful, since our masks protect *other people* more than they protect us. Pretty much think that any mask at all is good enough. Now if only everybody else would wear them!

All the studies I have seen suggest that cotton is the best option. That said, the ones I have that are made from Quilt fabric are quite warm. But I only have them on for short periods so I haven¡¯t looked for anything lighter.
Summer is here, and my current mask stock is getting stuffy.? I found this YouTube video that reviews testing done on various fabrics while I searched for options for lighter weight masks.
This woman has concluded that 90% poly and 10% lycra stretch chiffon is a viable alternative.? I'm not sure what I think.? 67% effectiveness with one layer, 83% with two layers.
