I have ordered both the disposable medical and surgical face masks from Wyze and received them both in a timely manner. My question is what is the difference between the $29.99 medical mask and the $39.99 surgical mask other than $10.00. The only physical difference that I can observe is the surgical mask has a thicker ear loop and the packaging is different.
Going by what I saw on a distributor/manufacturer site, the surgical masks are tested to a moisture / water resistance standard. Not speaking for the particular ones you got.
