Sick patients may also have viruses on the palms of their hands. If they shake hands with other people, the viruses are transmitted. Infection can also be indirectly transferred via objects such as door handles. Thorough hand washing is an effective way of preventing contact infections. Good hygiene practices support virus protection.
In order to protect against droplet or smear infection with Covid, many countries require by law that respiratory protection products be worn in certain areas of life. Where this is not the case, health institutes make important recommendations for protection against an infection. However, local and legal regulations must always be taken into account. In everyday life one encounters very different types of masks for covering mouth and nose.
In recent weeks, the topic has attracted a great deal of press media attention: But Wwhich respirators offer adequate protection against viruses?
What is the difference between a mouth-nose protection and a filtering half mask? Do self-sewn "DIY or community masks" protect against viruses at all? For better differentiation, please find here an overview:. The "daily-use masks" also called community masks include a large number of different masks. The spectrum ranges from DIY masks made of simple cotton fabrics to industrially produced masks without CE marking.
All of them are not approved as a medical product and may not be sold as such. Community masks can reduce the release of particles into the air, but do not provide adequate protection against infection with Covid However, they can help to prevent the carrier from touching his or her face as often and thus reduce the risk of a smear infection, e. Single-use masks should be disposed of in household waste after use. Mouth and nose protection MNP , also medical face mask, is known, for example, from the operating theatre as a surgical mask or from a treatment at the dentist, as it is usually used for patient protection.
Wearing a medical face mask from an acutely infected person can reduce the risk of infecting other people by retaining as much as possible of the droplets produced when coughing or sneezing. Therefore, the use of such medical face masks is already recommended or prescribed in some countries.
Such a mask only protects the wearer against larger droplets. The correct fit has a significant influence on the protective effect of a respiratory protection product. Since the MNP becomes soaked through with the duration of wearing it, it should be replaced after several hours, at the latest after the wearing period of one day.
Filtering Face Piece FFP half masks cover the nose and mouth and protect against respirable dust, smoke and liquid mist. They are made of rubber or silicone and are supplemented by various filter materials. The use of these masks is mandatory at workplaces that exceed the threshold limit value TLV of substances hazardous to health.
Protective masks of the classes FFP2 and FFP3 are also recommended for hospital staff, care workers and other groups of people with an increased risk of infection.
However, in everyday life a certified mouth and nose protection is sufficient to protect oneself adequately. There are different norms and standards for mouth and nose protection and respiratory masks worldwide. Here you can find an overview for better understanding:. Indoors, air filtration helps to minimize the risk of pathogens such as viruses and bacteria and to imporve the air quality. Therefore, high-quality, individually adapted air filtration systems are recommended, especially for sensitive areas.
The risk of infection is particularly high in public buildings and hospitals, as there are many people in confined spaces that can be potentially infectious. Here viruses can, for example, be taken up and passed on via door handles contact infection.
Droplets containing viruses can also be present in the air and enter the human body via the air we breathe droplet infection. In addition to the familiar hygiene measures such as frequent hand washing, keeping your distance or wearing a mouth protection, suitable air filter systems can effectively reduce the risk of infection indoors.
Perfectly matched filter stages separate almost all particles from the air and thus protect against airborne viruses. In addition, the level of fresh air should be increased as much as possible to further reduce the pathogen concentration in the room air.
In ventilation systems with recirculation operation, HEPA filters or high-efficiency fine filters should be used for virus protection if they do not generate a differential pressure that is too high.

Because nano material has high gas permeability, the formation of clad is to the not influence of gas permeability of filtrating chip grid. The active carbon filtration chip be placed on front side, kaolin filtrating chip be placed in the middle of, the zeolite filtration chip is placed on rear side, the active carbon filtration chip effectively blocks sticking granule, the kaolin filtrating chip effectively blocks myxovirus, and the zeolite filtration chip further blocks myxovirus, bacterium and thinner particle.
The superimposed arrangement of each filtrating chip, the lattice shape of each filtrating chip grid is inequality, perhaps the arrangement mode of grid is inequality, make the grid of different filtrating chips corresponding to the skeleton of compartment, the adhesiveness of nano material can effectively will be blocked with virus in the passing gas etc.
The air outlet of air-conditioner installing a slice, two or three above-mentioned filtrating chips can effectively block the virus of growing in the air-conditioning system etc.
Each filtrating chip uses after can regularly taking out disinfection repeatedly. The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment one, according to shown in Figure 1, a kind of air conditioning gas-filtering device of the utility model, it is made up of a slice or multi-disc filtrating chip, the filtrating chip periphery is a frame 4, frame 4 inboards are grid, grid frame is provided with the nano material clad, the nano material clad is nano level active carbon and rare earth, nano-kaoline and rare earth or nanoscale zeolite and rare earth, grid frame 2 is a metal material, macromolecular material or metal and macromolecule composite material, in the time of on being applied in domestic air conditioner, grid frame 2 is a nonwoven, and in the time of on being applied in central air-conditioning, grid frame 2 is the braid of stainless steel wire or other tinsel.
When it was formed for the multi-disc filtrating chip, the centre was square grid or garden shape lattice, and the lattice shape that is placed on the filtrating chip grid of front side and rear side is the opposite parallelogram of direction. Spraying active carbon and rare earth is activated carbon filtration chip 1 on the grid of filtrating chip, and spraying kaolin and rare earth is kaolin filtrating chip 2 on the grid of filtrating chip, and spraying zeolite and rare earth is zeolite filtration chip 3 on the grid of filtrating chip.
The mesh spacing of activated carbon filtration chip 1 is 0. Activated carbon filtration chip 1 is placed on the front side, and in the middle of kaolin filtrating chip 2 was placed on, zeolite filtration chip 3 was placed on rear side. Nano material adopts the preparation of calcining vapor method, and its granularity is for being the nanometer, and during less than nanometers, nano material promptly has various nano-meter characteristics according to the report granularity. Two kinds of nano materials are mixed in advance, are painted on the grid then; Also can be earlier on grid coating adhesive spray mixed nano material then.
