The Cone is designed with more breathing room. My husband prefers it to the Olson because it doesn't fog his glasses so much. It can be layered over a standard dust mask used in DIY and on construction sites. I think it's the best fitted handmade mask.
Main photo is me at a doctor's appointment, layering the cone over a disposable KN95 mask for extra protection.
My masks are constructed from 4-6 layers:
- 100% Cotton outer piece treated with waterproofing,
- Non-woven interfacing,
- Cotton or polyester batting,
- Non-woven interfacing, and
- Inner layer of soft cotton or cotton blend
With adjustable ear straps made from stretch fabric, for your optimal fit, and a metal nose piece to ensure form fit.
Care and More
Hand wash your mask in 30 degree water, removing the metal nose bridge and filter insert. Machine or line dry. Iron after wash.
PM2.5 filters are now widely available on eBay and Amazon at a low cost. Or use the one I've supplied as a pattern for your own replacement, using Shop Towels, Baby wipe, HEPA hoover filter bag.
For added protection, especially on crowded trains, I recommend wearing this mask over a disposable surgeon's mask, or KN95 mask. It's hot and stuffy, but it's worth the added protection.
Remember not to touch your face when wearing.
