Face masks of different types have been in demand ever since the coronavirus outbreak became a global pandemic.
As the Covid-19 virus keeps mutating and the global pandemic shows no sign of abating, more and more people are choosing to wear face masks.
It means defying the advice of the World Health Organization (WHO), which suggested that masks were mandatory only for the sick, not the healthy. Health officials of different countries have started to come around to masks as they did help in slowing the spread of the virus in Austria.
Apart from health workers, security officers and cashiers in supermarkets, regular commuters and blue-collar workers who take public transport have started wearing face masks in public.
Some masks are effective for days, some are for hours. Here's a breakdown of different types of masks.
The United States National Institute for Occupational Safety and Health (NIOSH) has standardised N95 face masks. The “N” stands for “not resistant to oil,” while “95” represents its minimum 95 percent filter capacity for catching viruses as small as 0.3 microns.
The N95 respirator reduces the wearer's exposure to tiny, invisible particles in the air, including bacterias and many viruses. the cough or sneeze droplets are blocked inside the mask and it prevent viruses to enter as it claim to filter 95 percent of airborne particles, respectively.
There are also R and P series which differ from N in terms of their resistance to oil. R and P are respectively somewhat and strongly resistant to oil.
Face Filtering Piece (FFP)
Face Filtering Piece (FFP) face masks are a rage in Europe. They are divided into three categories, FFP1, FFP2 and FFP3. According to the European standards, each type can filter 80, 94 and 99.95 particles down to 0.3 microns. They are equivalent to N95 in Europe.
EN 149:2001+A1:2009 represents the most recently accepted and current standards by the European Committee for Standardization (CEN).
FFP1 type is the lowest level mask for the protection. Generally, people who have respiratory diseases use FFP1 to avoid being affected by dust and similar substances. It can't keep the coronavirus at bay, however, as it is exclusively meant to be against toxin-free dust.
The FFP2, provides additional protection from chemically-laced air particles and dust, and is recommanded in most of the case because it's the cheapest way to protect the wearer and also prevent for secretions.
Surgical masks are generally used to protect the wearer from large-particle droplets, sprays and splashes. It also prevents potential infectious respiratory secretions to others. However, it is considered to be weak against the coronavirus.
