If you are concerned about catching coronavirus or infecting movers, it is a good idea to invest in an N95 mask. These are the most protective, as they keep out droplets and airborne virus particles.
Even with such a mask, it is important to maintain six feet distance whenever possible, as it further lowers the chance of catching or passing on the virus.
If you are unable to get an N95 mask, a surgical mask is a good alternative. You may also want to consider goggles to protect your eyes. For more information, visit the CDC website to understand coronavirus guidelines.
