Masks......they are 'sneeze shields', not HEPA filters....in most cases.
This is true but the virus is transmitted on liquid droplets. It's not especially airborne except as it can attach to a droplet that stays suspended in the air. So it's the droplets that are larger than the virus that we're attempting to filter out and masks do a decent job of that if we keep our distance as well and use a mask that's close fitting and densely constructed.
