Air pollution

There are many side effects of air pollution on human health as it is highly dangerous and carcinogenic. It causes cancer, cardiac diseases, pulmonary and blood circulation related diseases. There are a very few research stations which are working to provide solutions against air pollution. A very few researchesare conducted to overcome the disastrous effects of air pollution.

In the last twenty years, the air quality is improving day by day across the world (HKEPD, 2016a). However, the pollution caused by PM_2.5 particulate is continued to increase day by day according to guidelines of safety made by WHO (World Health Organization), though the limit of World Health Organization has been changes now from 185 days of PM_2.5concentration in 2012 to 126 days in 2016(WHO, 2014; HKEPD, 2016b). PM_2.5is a particle smaller than 2500 millimetre in diameter.PM _2.5 is a pollution causing agent which can cause many diseases like cancer, asthma and cardio-pulmonary diseases (Pope and Dockery, 2006; Pui et al., 2014). However, its health impacts may not be evenly distributed across all socio-economic groups.

What are indoor air contaminants?

Examples of basic atmospheric pollutants and their main sources are as follows:
• Building residents' carbon dioxide (CO2), tobacco smoke, aroma, and personal smell.
• Building materials such as dust, fiberglass, asbestos, and gases, including formaldehyde.
• Toxic fumes, unstable natural mixtures: chemical products used in the workplace, solvents,            pesticides, disinfectants, pastes.
• Gas, steam, smell: gases from furniture, covers and paintings.
• Parasitic dust: from floor coverings, textures, foam pads.
• Microbial contaminants, growth, mould, and microbes from wetlands, stagnant water and condensate.
• Ozone: printers, motors and electrostatic air purifiers.

Indoor Air

Indoor air pollution has a greater impact on the developing country than on developed country, as fuels such as wood, coal and biochips are burned in houses for cooking and heating. There is very little ventilation to allow the poison to escape, so the occupants of these houses will eventually absorb carbon monoxide and several dangerous pollutants. Indoor air toxins caused by household fuel consumption cause real medical problems such as pneumonia, bronchitis, malignant growth, coronary heart disease and asthma. In addition, since most people in developing countries do not have other cooking and heating technologies, it is not surprising that indoor air pollution caused by fuel-related murders. In indoor buildings, there are 1.6 million people every year.

Think about it: A normal American spends 90% of his life indoors. Include this with how indoor air you are currently thinking about getting dirty and creating dangerous situations! For developed countries, for example, the United States, snuff smoke isa most dangerous toxin from indoor air. Whether you smoke or not, cigarette smoke can cause many medical problems that are not separate from cigarettes such as lung cancer, emphysema, asthma and coronary heart disease. Lungs, absorbing even more than 4,000 synthetic compounds, many of which are carcinogenic or malignant synthetic compounds.Smokeis also dangerous inside, this is the second reason why malignant lung growth in the United States (smoke is the first). Radon is a radioactive gas from the normal failure of uranium in soil, water and vibration. As the uranium separates, the helium filter can enter the structure.Radonis particularly dangerous because it is dull and boring, so it is difficult to find out that there is no special team test (Friedi, 2018).

Air filters

Many inorganic and organic volatile compounds and other particles are generated and deliberately present in indoor air. They can go inside the body, when a person inhales then they enter in the lungs and cause serious carcinogenic and chronic diseases (Jo and Park, 1998; Lee and Zhu, 2014; Linders et al., 2007; Muala et al., 2014). In this way, fibber-based filtration is a simple and conservative idea that overcomes the deleterious effects of particles and VOCs during the spray process. Several surveys have been conducted with a focus on simple manufacturing steps and cost-saving technologies (Szekely et al., 2014; Wang and Otani, 2013).More specifically, the inventive nonwoven fabric has been used in the channel layer for a long time; the nonwoven fabric produced by electrospinning or liquefaction inversion has become a filter medium having a small pore size and a large surface area (Hassan et al., 2013; Zuo et al., 2013).In addition, the air channel implanted in the CA was used for the ventilation jacket after the found carbon was found to control the VOC and by mixing the strong materials that adsorb the contaminants and natural synthetic materials. Therefore, these channels are used in automobiles and as a regulating channel (Dillon et al., 1997; Geiss et al., 2009).The frequency of the air passage should be changed depending on the type of air passage, the general quality of the indoor air, the number of pets in the house, and the number of people involved in the household and the size of air pollution and development around the house.

How to clean air filter

Turn the switch off before touching the channel. Use a brush or vacuum to clean the area around the vents before opening the vents. Open the screw or lock and open the ventilation grille. Vacuum the envelope area and remove the air passage. Optionally, the frame is not removed first, it will inhale the float and the spray during the cleaning process. If ventilated in the ceiling or top divider, use a stool as a stage. Put the channel into the outside bin. Associate the pipe connection to the cleaner. Vacuum debris, burrs and ejector from the channel have a fill connection at the front, rear and sides of the channel. If possible, vacuum the outdoor passage to avoid residue in the mixing chamber.

Add a hose to the faucet. Keep the channel so that the water flows in the opposite direction of the wind. Completely shower the canal to clean waste and dirt. Use a delicate touch instead of all the power of the hose to avoid damaging the passage. If the basic wash is not active, it can absorb its passage with a cleaning system. Add a drop of mild dishwashing detergent to the warm water in the container. Mixed arrangement. Wet the fabric in the arrangement and clean the sides of the channel. Wash the canal with water and let it dry completely. After the last rinse, remove excess water and allow the sieve to dry. If you are exposed to oil, smoke or pet hair, you may need to clean the chain with detergent. Praise the dry canal with a paper towel. Leave the channel outdoors and allow it to dry in the air. Make sure the channel is completely dry before reinserting. Not allowing the passage to dry completely can lead to the development of the form, which can spread spores throughout the house through heating, ventilation and air conditioning systems. Put the chain back in the slot. Make sure the wind looks as good as possible. Close the vents and secure the screws or locks. The chain should sit comfortably, not too small or curved. Make sure there are no holes (Air Conditioning Filters Guide, 2018).

Molekule Technology (air purifier)

Purifying indoor air is need of the society now a day, as there is very much air pollution across the world. Molekule's technology is one of the best technologies being used to purify the indoor air. Latest purifiers are available in very reasonable prices $450-600. Molekule take the air from every direction in the air. Pre-Filter is always filled with the surrounding air – air circulate in the pre-filter and trap the dust and dander and slow down the volatile compounds on their ways and destroy them before PECO-Filter.

How does air pollution affect health?

Air pollution is a real health hazard for California. According to the California Air Resources Board (ARB), more than 90% of Californians have regretted air pollution at least once in the year. The introduction of air pollution during pregnancy is also associated with a decrease in birth weight, rashness and infant mortality. In children, the introduction of air pollution is also associated with changes in lung function, respiratory tract irritation, asthma and other serious respiratory infections. In adults, air pollution is associated with transient infections and accidental heart and lung infections. As described by ARB, the introduction of particulate and ozone emissions resulted in 8,800 accidental deaths per year, and 210,000 asthma and other lower respiratory symptoms in California.
