Options besides N95s include a well-fitting three-layer cloth mask with a non-woven polypropylene filter layer, medical masks that are ASTM certified, and wearing a good-fitting cloth mask over a medical or procedure mask, expert Catherine Clase says. It’s a question many parents and caregivers are asking, as Omicron causes a surge in COVID-19 cases and children in Ontario prepare to return to class. For people who can source and purchase these respirator masks, Clase recommends checking with the manufacturer for guidance on sizing. Another option is a good-fitting cloth mask over a medical or procedure mask. With N95 masks in short supply, Clase notes any mask will offer some level of protection.
