It’s been almost a year since coronavirus changed the way we live. Masks are an additional step that we can take to prevent the spread of COVID-19.

Recently, the CDC conducted several experiments to assess methods that improve mask performance. One of the methods that they tested was the effectiveness of wearing two masks. This begs the question, “Does double masking help against COVID?”

According to the January 2021 CDC study, wearing double masks or a single fitting mask more closely on the face can substantially reduce your risk of infection with coronavirus. [Source]

The experiments found that wearing a three-ply cloth mask over a three-ply medical or surgical mask will block 92.5% of particles from a cough, and a single surgical mask only blocked 42% of the particles, while cloth masks block 44.3%.

Medical and engineering experts recommend upgrading your masks especially since new variants of the coronavirus are spreading around the US and some are significantly more transmissible. The information found in doing these experiments are not intended to change any current recommendations about wearing a mask, but to “provide new information on why wearing a well-fitting mask is so important to protect you and others,” CDC Director Dr. Rochelle Walensky said during a recent White House briefing.

The CDC’s recommendations have generally focused on cloth masks because of a previous shortage of surgical masks and N95 respirator masks for health-care personnel. But since supply has improved, the CDC’s goal is to provide more information about the pros and cons of different masks so that you, the consumer, can make more informed choices about what you want to use. The agency still does not recommend that consumers wear N95 respirators. [Source]

The Centers for Disease Control and Prevention recommends the following to improve how your mask protects you:

  • Make sure your mask fits snugly against your face.
    • Do:
      • Choose a mask with a nose wire.
      • Check for gaps between your face and the mask.
  • Pick a mask with layers to keep your respiratory droplets in and others out.
    • Do:
      • Use a cloth mask with multiple layers of fabric.
      • Wear a disposable mask underneath a cloth mask.
        • The second mask should push the edges of the inner mask against your face.
    • Don’t:
      • Combine two disposable masks.
      • Don’t combine a KN95 mask with any other mask.
        • Only use one KN95 mask at a time.

Don’t forget your valve caps! RZ Masks were around long before the pandemic and were designed for recreational dirt biking, woodworking, working outside, and any other tasks that can expose people to particles that they do not want to inhale. The CDC recommends that masks with valves not be worn since they are designed to protect the wearer and are not guaranteed to stop the spread of virus-carrying particles. Some states and counties in the US have even restricted masks with valves during the ongoing pandemic. The RZ Mask Valve Caps are the answer to these restrictions. Simply replace the existing one-way exhalation valves with these caps for ultimate protection. These caps will stop air from passing through and will force your exhaled breath back through the filter of your mask.
