DESC: BACKGROUND
Technical Field
[0001] The embodiments herein generally relate to a filter, more particularly to a detachable filter that can be applied on any type of face cloth worn by a user that provides flexibility and comfort in covering the nose and mouth to make it as a face mask to filter particles from the air.
Description of the Related Art
[0002] There has been need for using face masks to prevent influenza and similar airosole transferable deseases while using public places. Face masks are also essential in areas with vehicular or industrial pollution leading to bad air quality, especially to vulnerable population with existing lung deseases, advanced age or for young children. Face masks are used everywhere, leaving the house, in shops, in grocery stores, on bicyclists and the like. According to the American Lung Association, one in four people infected with disease, say COVID-19, might show mild symptoms or none at all. In the US, the Centers for Disease Control and Prevention revised the official guidelines to recommend wearing a “face covering”. The most important thing is to cover entire nose and mouth, which means that the face mask should fit underneath chin. There are numerous types of masks that includes N95 respirator masks that are used especially to protect medical workers who come into contact with high doses of the virus while visiting and carrying out medical procedures on multiple patients, medical masks that filters about 60 to 80 percent of particles then homemade fabric masks that covers nose and mouth. These face masks are expensive for common people. Also, it requires longer production time and this may create inaccessibility of the face mask for the masses. Unavailability of the face masks leads to simpler material being used. for example, a face cloth tied around the face.
[0003] Using a face cloth when around others may block large particles that might eject through a cough, sneeze or unintentionally launched saliva (i.e. through speaking), that could slow the spread of transmission to others. The homemade fabric masks are fast and efficient to make at home, with a sewing machine or sewn by hand. Many sites provide patterns and instructions that use multiple layers of cotton, elastic bands or ordinary thread and the like. The homemade fabric masks are created as a fashionable way to keep away from breathing in large particles, like car exhaust, and air pollution. But those homemade fabric masks has no strong scientific evidence that the masks confirm to the face tightly enough to form a seal. Meanwhile, the homemade face masks can get muddled as the risk of not blocking of large particles in public and how much can a face cloth covering protect. Using the face cloth covering the nose and mouth, is also less effective as it is a normal cloth made from cloth fabric.
[0004] Accordingly, there remains a need for a detachable filter that can be applied on any type of face cloth worn by a user that provides flexibility and comfort in covering the nose and mouth to make it as a face mask to filter particles from the air.
SUMMARY
[0005] In view of foregoing, an embodiment herein provides a filter that is adapted to attach to a cloth to filter contaminant particles. The filter includes a first layer, a second layer, and a third layer. The first layer is placed on a first side of the filter. The first layer is configured to paste the filter on the cloth using a filter paste. The second layer is placed on a second side of the filter using a first side of the second layer. The second layer is configured to absorb sweats of a user. The third layer is placed on between a second side of the first layer and a second side of the second layer. The third layer is configured to filter the contaminant particles from ambient air entering into the filter, thereby providing protection against viruses and bacteria.
[0006] In some embodiments, the filter is a detachable filter mask that is adapted to attach to at least one of a first side or a second side of the cloth to filter the contaminant particles.
[0007] In some embodiments, the first layer includes a peel off sticker. The peel off sticker is configured to at least one of paste the filter on the cloth or peel off the filter from the cloth after usage.
[0008] In some embodiments, the second layer includes a sweat absorbent layer. The sweat absorbent layer provides absorbent in at least one of a boundary layer or a bottom layer.
[0009] In some embodiments, the third layer includes a filtering sheet that blocks particle droplet, splashes, sprays, or splatter that includes viruses and bacteria, from the ambient air entering into the filter.
[0010] In some embodiments, the first side of the filter includes outer edges of the filter.
[0011] In some embodiments, the filter includes a supporting sheet that provides structural support on the outer edges of the filter. The filter is in a triangular shape to cover a nose and mouth of the user.
[0012] In some embodiments, the second layer prevents the third layer from getting clogged with the sweats of the user.
[0013] In some embodiments, the outer edges of the filter include heat sealed edges with grooves to attach the first layer, the second layer and the third layer.
[0014] In some embodiments, the filter includes one or more filtering sheets to filter the contaminant particles.
[0015] The filter in the triangular shape does not include any straps and enables the user to wear it easily with any cloth. The filter is adapted to provide flexibility and comfort in covering the nose and mouth of the user. The filter reduces exposure of the user’s saliva and respiratory secreations to others, and blocks harmful pollutant particles more than a filter hole diameter from entering into the filter. The filtering sheet in the filter blocks particle droplet, splashes, sprays, or splatter that includes viruses and bacteria, from the ambient air entering into the filter.
