A cloth face mask, sometimes called a nasal mask, is typically a plastic mask worn over either the nose and mouth or over only the nose. Because cloth is easy to remove and replace, this type of face covering has many practical applications. It is used in hospitals and nursing homes to prevent irritations from the air, as well as from patients who have foreign objects in or around their noses. Cloth face covers are often used during sports events to protect athletes’ skin from scratches and abrasions.
When using a face mask, one method of ventilation through the cloth is through a series of small openings at the top. The droplets of the patient’s breath are accumulated and then directed through the small openings at the top of the device. This directs the droplets to another collection bag at the bottom of the device. The bags are closed off by Velcro straps. A face mask can be adjusted to allow for varying amounts of air to be supplied through the air openings.
Another application of a face mask is to keep the patient from expelling air from the nose through the mouth. Some people suffer from a condition called Botox, in which the muscles that hold up the roof of the mouth are weak and allow air to escape. This condition, known as “traction alveolar depression”, or BAD, makes it difficult for the person to breathe. Cloth masks that contain abrasion resistance and are equipped with exhalation valves can be used in order to prevent the escape of air from the nose and mouth. These masks may also have an additional feature of sensors that can measure the amount of moisture in the patient’s mouth and use that information to determine whether the patient needs re-plucking of the facial hair.
The design of modern face masks contains multiple layers of fabric. In some instances, the fabric is comprised of one or more layers of soft vinyl. Soft vinyl is beneficial because it can withstand the abrasion of facial hairs that occur as patients brush and wash their hair. The vinyl also provides extra abrasion resistance during the wash process, when it comes in contact with water. The vinyl can also add additional strength and stability to the face mask, because it can be cut into multiple layers to address issues such as droplets. Droplets are a problem with some forms of soft vinyl face masks, but many manufacturers have addressed this issue through the addition of multiple layers to their masks.
Face masks can be worn to distancing tasks as well. During normal activities, the wearer must determine the distance between themselves and whatever they are performing the task with. A face mask may be worn in order to increase the wearer’s visibility and thereby increase their ability to perform tasks.
There are two primary styles of face mask to wear. One style is fully closed and the other style is fully open. The fully open style has a face mask that covers the entire nose and mouth, while the closed style has a half face mask which creates an opening for air to flow through. Many people choose to wear a full-face mask when doing work involving heavy machinery or when they are outdoors and face temperature changes could affect their breathing. The covid-19 style is the ideal mask for someone who works at home. This mask has a small opening in the top half of the mask, allowing airflow through the mask’s nasal cavities.
