Types of face masks

Here is our quick overview to the different types of face masks available.

N95/N100 and FFP2/FFP3 Masks

  • N95/N100 designations are used in the USA and are roughly equivalent to FFP2/FFP3 in the EU.
  • FFP3/N100 masks are the highest rated masks available, and protect the wearer from aerosols and droplets at concentrations up to 50X occupational exposure limits (set by health organisations).
  • These are needed and used by medical professionals in direct, frequent contact with patients known to have an infectious respiratory disease.

Surgical Masks

  • Surgical masks protect the wearer in a similar way to N95/FFP2 masks, however they are less effective than these.
  • They will protect the wearer from respiratory droplets which may approach the face, however are fitted less firmly to the face and filter less effectively than an N95.
  • These are being used by medical professionals as a precaution when treating any patient, in case they may also be an asymptomatic carrier in addition to their presenting medical complaint.

Home-made Masks

  • Home-made masks are not regulated or confirmed to protect to any given standard.
  • However, if the majority of people wear a mask of some form, evidence shows a reduction in disease spread.
  • This is particularly important for people who may have asymptomatic infections and not know that they are spreading the virus while out of the house.
  • Any time you are outside the house in an enclosed or crowded space you should wear a face covering if you can – this includes supermarkets and public transport.

Why did the advice change suddenly?

Research!

Remember we are forever learning: advice and guidance will evolve as we learn new things.

Previously, home-made masks were not advised, as they are less protective than medical masks and individually do not provide full protection to the wearer.

However, new research is now showing that the limited protection given through reducing droplet spread from the wearer is worth it. In addition, the net gain of everyone wearing one is much greater than just the actions of one single person.

Do face masks with valves protect others from me?

Do face masks with valves protect others from me? No

😷 Evidence for wearing face masks when in close contact with others is still growing – but make sure to be selective with what you use to protect yourself and others as much as possible!

💨 Masks with a valve that lets air out might feel more comfortable, but they reduce the efficiency of the mask’s protection.

💦 This reduction in efficiency can let respiratory droplets from you fly towards others, risking infecting others if you are infected and don’t have symptoms.

🦠 To protect yourself and those around you, stick to masks without a valve – even homemade cotton masks are effective at stopping droplets!

Lockdown eases, but the virus has not gone away.

Post originally on instagram

So things are opening up again this weekend (4th of July 2020) in the UK. The lockdown eases.

It is everyones individual choice where they wish to go now and what they want to do – if you are looking for ways to reduce risk while going out and seeing friends, here are some science-based suggestions:

Effective hand washing is still extremely important! Make sure you’re washing frequently and efficiently!

 Masks are still growing in evidence for their effect in slowing disease transmission. When you’re in close contact with people outside of your household, consider wearing one as often as you can!

Check out yesterday’s post for how to put on and wear your mask safely!

If possible, meet outdoors! Respiratory droplets have a reduced risk of reaching the people you’re with if you’re outside – a walk or a picnic are good alternatives to a sit-down meal.

Reduce the number of people you see in short spaces of time. By distancing the different groups you see you can reduce the number of potential infections in a social group.

How to use gloves correctly

Post originally on instagram 1.05.20, updated 9.07.20

Let’s talk about gloves and how to use them correctly.

Wearing PPE is a way to prevent the spread of diseases, but only if used correctly. Gloves aren’t necessarily advised throughout the pandemic – unless you work in certain professions – but we have had many questions about gloves. So we have done our best to give an overview on how to wear gloves correctly, if you chose to wear them.

We have discussed the risk of wearing masks incorrectly and how this can put you at more risk, tonight we focus on the correct usage of gloves. 🧤

  • Wash your hands thoroughly with soap and water, before AND after using gloves
  • If you are wearing gloves to protect yourself, the material of these gloves are very important.
  • Gloves should be changed frequently to reduce risk of spreading diseases
  • When removing your gloves, do it so your hands do not come into direct contact with the outside of the gloves.
  • Improper use of gloves increases the risk to you and those around you.
  • Good hand hygeine practice is a more favourable preventative measure.
  • PPE is in high demand in healthcare settings, social distancing and hygiene should always be adhered too.

Any questions are welcomed, as always.

How to wear a face mask correctly

The evidence for public use of face masks is evolving. Different masks have different levels of efficacy and it is STILL of the utmost importance that surgical and N95 masks are saved for the healthcare workers who need them 👩‍⚕️ IF you decide that you are going to use a face mask, you MUST use it correctly – otherwise you are just putting yourself and others at more risk! 😷 So, how do I wear a mask correctly?

Donning and doffing your mask is a high risk portion of PPE wearing. You MUST NOT touch the front of your mask at ANY TIME!! This is the portion of the mask that is collecting droplets to protect you from the virus 😪
If your mask has a metal band, this should sit across your nose and be pressed down and moulded to shape 👃

Your mask MUST cover your nose and mouth completely, with no gaps! Even tiny gaps caused by facial hair reduce the efficacy of masks (this is why many healthcare workers have braved the shave!) 🧔

And finally, you should wash or dispose of your mask and clean your hands as frequently as possible. PPE does NOT make you invincible and does not replace social distancing or hygiene measures. It should only be used in addition to good practices already in place💧
