CDC recently published new guidance on types of masks, including which masks offer the most protection. Cloth masks provide the least protection from the Omicron varient and are little more than face decoration. N95s are the most protective and paper surgical masks are in-between. KN95s are also in-between unless they are cheap knock-offs like 60% of the ones tested. Poor fitting masks with gaps around the sides offer little protection.
To reduce the potential to contract the disease, wear the most protective mask you can that fits well and that you will wear consistently.
In related news, the federal government will be providing free N95s. Three free masks per person can be picked up at local pharmacies in early February.
