States with Mandatory Face Masks

In light of all the new states requiring mandatory face masks, I have been wondering how many states have those requirements now.  

I did an internet search and found this at a website called Littler

Facing Your Face Mask Duties – A List of Statewide Orders, as of July 3, 2020

According to this site, all states require masks except Alaska, Idaho,Missouri,South Carolina,South Dakota, and Tennessee. These states recommend you wear masks.

Iowa, Montana, and Oklahoma are the only states who have no requirements at all, according to this list.
