I have to go to the dentist, chemist and supermarket tmrwn but which face mask should I wear?

These are surgical face masks designed for surgeons not to breathe onto patients during operations
They don't offer good protection against an airborne virus
It's not sealed so the virus can sneak in from the sides

These are known as N95 face masks
They provide a better fit which reduces the risk of an airborne virus getting in
However there is no oxygen supply so you are just breathing in the same air as you are breathing out, carbon dioxide
And if you wear glasses as I do the air you exhale leaves the small gaps around the nose causing glasses to fog up
