What Are The Different Types of Face Masks?

Respirators

Respirator masks are secured tightly around the face and have an adjustable clip around the nose so that few particles can enter. They are available in different models, including N95 (FFP2), N99 and N100. The coronavirus particle is thought to be around 125 nano meters in size. This means that respirators provide a high level of protection against COVID-19.

• FFP2 masks, also known as N95 masks, can filter 95% of particles that range in size from 100nm to 300nm
• FFP3 masks, also known as N99 masks can filter up to 99% of similar particles
• N100 respirators have the ability to filter up to 99.7% if such particles

Respirator masks are able to provide a higher level of protection against viruses. They are usually marked with an approval rating (N95, KN95, FFP2 etc.). Respirators can also come valved or unvalved. A valve helps to release air on the exhale, which can reduce sweat build up and reduce stuffiness. Unvalved masks are lighter and less bulky, making them easier to transport.

Surgical Masks

Surgical masks are also available in different variations. They are designed to prevent large droplets such as mucus or spit, being expelled from the user. Whilst surgical masks offer an element of protection, they are not effective in filtering small particles in the air. A Type IIR surgical face mask offers more protection against splashes and is considered to be fluid resistant.

Cloth Masks

A cloth mask works by capturing the respiratory droplets emitted when the wearer speaks, coughs, or sneezes, serving as a shield that prevents the wearer from inhaling droplets dispersed by others.

Cloth masks offering the highest protection are crafted from multiple layers of densely woven cotton. The effectiveness of a mask is increased with additional layers, which help block droplets from passing in or out of the mask.

Do Face Masks Protect Against Coronavirus?

Face masks help to prevent contracting and transmitting coronavirus disease. In fact, any form of covering over your face will be effective. Coronavirus is spread through inhalation or contact with droplets of the virus. Wearing a face mask will prevent a large percentage of droplets from entering the respiratory system. Whilst masks are unable to provide 100% protection, they will most certainly reduce the risk of infection. 

Best Practices for Better Protection

• Choose a Well-Fitting Face Mask: Ensure the mask covers both the nose and mouth completely. It should fit snugly against the sides of your face without any gaps to maximise protection.
• Clean Hands Before and After Handling: Always wash your hands or use hand sanitiser before putting on your mask and after removing it. Avoid touching the face or mask front once it’s on to prevent contamination.
• Wash Reusable Masks: If using a fabric mask, wash it after each use according to the manufacturer's instructions at the highest appropriate temperature.
• Discard Disposable Masks Responsibly: Properly dispose of single-use masks after one use and do not reuse them. Throw them away in a closed bin immediately after removal.
• Monitor Mask Condition: Regularly check your mask for signs of damage or wear. Replace fabric masks if they become wet, soiled, or deteriorated in any way to maintain effectiveness.

Can You Reuse a Face Mask?

You should not reuse a face mask. They are intended for single use as masks may be contaminated with infected droplets. You should not touch the front of a face mask, and it should be taken off from the ear straps. You should wash your hands before and after taking a mask off. The structural integrity of a mask may also be compromised once it has been used, which can make it less effective when used again.

Can I Wear a Face Shield Instead of a Mask?

While providing eye protection experts advise against relying on face shields instead of masks because their effectiveness is uncertain. Nonetheless, in scenarios where face masks cannot be worn, wearing one may be necessary. If so, ensure it wraps around your face's sides and extends beneath your chin.

What Else Can I Do to Protect Myself From COVID-19?

Practising social distancing can reduce the transmission of covid. Regularly washing your hands and avoiding touching your face will also help to reduce transmission of virus droplets. Wearing disposable gloves when going into public places and using hand sanitiser throughout the day is good practice.
