When you are leaving your house, how do you decide what mask to wear that day? Have you tried different kinds? Masks have become a new part of our daily life. We all have to wear masks in social situations or anywhere out in public in order to prevent ourselves and others from contracting coronavirus. In the past few months, there have been many different types of masks that are being sold. Some even have super cool designs, and some are more comfortable than others. So, when you are picking a mask, do you stop and think about which one is the most effective at doing its job of protecting you?
Overview on Masks and the protection
The article from Healthline explores the variety of masks, and discusses the usefulness. In general, masks are an essential preventative measure to take as it reduces the risk of transmission of Covid-19, along with the other protective measures, such as distancing and proper hygiene. The purpose of masks are to protect oneself from the respiratory droplets from traveling into the air. It is especially important to protect yourself in public because around 80% of the coronavirus transmission has been rooted from asymptomatic carriers. An asymptomatic carrier is someone who has contracted the Coronavirus, but has no symptoms of the virus. However, asymptomatic people can still spread the virus. By wearing a mask, one is able to prevent the airborne transmission of the coronavirus pathogens through our bodies primary defenses such as the mouth, nose and the eyes. Since the coronavirus pathogens are able to get past the barrier defenses if you do not wear a mask and take other preventative measures, this triggers innate cellular defenses, which lead to the inflammatory response in our body, such as fevers, colds and more. Inner surface is lined with tiny hairs cilia or mucus membranes which trap pathogens and can be removed by sneezing or coughing or swallowed to be broken down by stomach acids.
Surgical Masks and Valve Masks
Surgical masks are disposable, single use masks that cover your mouth and nose. They are made out of a breathable synthetic fabric. There is not a airtight seal around the area it covers, and there has been a large range on how the surgical masks filter pathogens. Respirators have intense filters that filter the pathogens in the air. These are also airtight, unlike the surgical masks. Some of the respirator masks have valves which lets some exhaled air to escape. The downside to this is that it does not protect others from pathogens exhaled through the valves. This is because the valves in the mask allow respiratory droplets from the person wearing the mask out into the air and get to other people.
N95 Respirator Masks
N95 masks can protect one from particles as small as 0.3 microns. N95 masks are extremely effective in preventing airborne particles from entering through the areas of the nose and mouth. The name “N95” comes from the fact that the respirator blocks 95% of small and large particles out. The ‘N’ is the respirator rating class. The ‘N’ stands for “non oil”, so basically no oil based particulates are present. The filtering and protection is much higher than a surgical or a cloth mask.
Homemade and store bought Cloth Masks
Masks that many people make at home are considered to be the least effective as the fabric is less secure and allows for small droplets to enter inside the mask. Also, many of these cloth masks have gaps near the nose, jaw or mouth area that also be areas where the droplets can be inhaled by the person wearing the mask. If you do wear a mask made at home, use 100% cotton fabric, which is the most effective material for cloth masks. Now, most stores are selling all different kinds of cloth masks. In general, all cloth masks vary with effectiveness as they are constructed with different fits, materials, and layers which all effect filtration. But, overall, store bought masks have had better securely fitting masks, which is very important in wearing a face mask for protection to properly cover the nose and mouth. If you are buying a cloth mask from a store, look for cloth masks that come with a nose wire and a filter insert which upgrade the masks. Overall though, whether it is homemade or store bought, surgical and n95 masks are more effective than both in protecting the wearer.
Overall, a key factor in any mask usage is how you wear the mask. Have you caught yourself accidentally letting the mask slip off your nose, and not doing anything about it? The proper usage is extremely important in having the masks be effective and prevent ourselves from getting the virus. We are in a very critical time, and the least we can all do is wear a mask to protect ourselves, others and lower the spread of the virus. We can all help reduce transmission! Be sure to wear a mask and be safe!
