Since the start of the pandemic, mask guidelines have evolved as public health officials continue to gather information on the spread of SARS-CoV‑2, the virus that causes COVID-19. Masks have proven to be a critical tool in protecting both yourself and others from spreading the virus. However, masking guidelines can be intimidating to keep up with as there are many changing recommendations around which masking techniques best protect you.
When to wear a mask
It is recommended that you and everyone in your family that is over the age of 2 wear a mask when you may encounter another person outside of your household, according to the Center for Disease Control and Prevention (CDC). Many public places, including schools, healthcare clinics, restaurants, stores, and event venues, require you to wear a mask. Effective February 2, 2021, masks are also required on planes, buses, trains or other forms of public transportation within the United States. Masks help slow the spread of COVID-19 by shielding you and others from respiratory droplets that are released when someone talks, coughs or sneezes.
Types of masks1
Regardless of which type of mask you choose to wear, it is important to find one that fits properly to your face and does not gape open on the sides.
- This type of mask is made of the same synthetic material as N95 masks that are currently reserved for healthcare workers. Both get their name due to the masks filtering out and capturing 95 percent of particles.
- This mask should have 2 – 3 fabric layers of breathable material such as cotton.
Non-medical disposable masks
- Ideal for situations in which your mask may get wet or dirty.
Neck gaiters or bandanas
- While neck gaiters and bandanas do not fulfill the masking requirements in healthcare settings, schools, federal properties or on public transportation, these alternatives are better than no face mask at all when a mask is needed. Gaiters and bandanas should have two layers of fabric and be secured properly to your face to be the most effective.
As a result of more contagious, mutated strains of the COVID-19 virus making their way to the United States, the CDC began to study the effectiveness of wearing two masks at once. Their findings, released February 10, 2021, found that wearing a non-medical disposable mask under a cloth mask increases the mask’s effectiveness in blocking out contagious respiratory particles2. For added effectiveness, you can tie the disposable mask’s ear loops in a knot behind your ear for a tighter fit. This will help close in any of the mask’s gaps on the side of your face and, as a result, increase your protection from COVID-19.
Caring for your masks
If you plan on reusing your mask throughout the day, it is recommended that you store your mask in a paper bag after proper removal. To remove your mask properly, grab the loops that secure your mask to your ears and then fold the mask’s outside corners together. This will help preserve the cleanliness of the inside of the mask for future use. To wash a reusable mask, you can include it with your other laundry at the appropriate washer setting. Masks should also be fully dried before your next use3.
If your mask is disposable, you should throw out your mask after a single use or change into a new one if the mask becomes wet or dirty.
As we continue to learn about COVID-19 and more research is done by experts in the field, we need to maintain our current safety practices including social distancing and masking. Masking remains a critical element in the fight against COVID-19, and it is recommended that those who are vaccinated, waiting to be vaccinated or choose not to be vaccinated continue to follow masking guidelines.
