New Indoor Air Filter Used In Filter Media - Air Filter - Filtration And Separation Industry

Abstract: The paper on the commercial and residential HVAC

, portable air purifiers and vacuum cleaners of the latest innovations filter media, the use of the technology level can be achieved MERV16 filter pressure drop lower than MERV10 filter. Compared with other commodities, filters, excellent performance by the media made portable HEPA air purifier in the CADA can increase by 10% to 30%; vacuum cleaners used by the newly developed filter media made of filter performance greatly improved.

As people understand the importance of indoor air quality improvement, air filters have become the needs of many families, including those used in residential heating and ventilation and air conditioning systems (HVAC), portable air purifiers and vacuum cleaners, so the air filtered trend is filtering to provide better performance and longer life cycle of the more advanced filtering system. In these applications, a variety of filtration systems use a different technology and a wide range of filter media. A proprietary filtration equipment reduces the efficiency of the concentration of particulate matter filtration efficiency of equipment and air handling capacity of the function.

Of this paper is the latest on the commercial and residential HVAC, portable air purifiers and vacuum cleaners, filter media innovation. As these applications, so that filter media technology with superior performance has made breakthrough progress. Use of the filter media technology to achieve the minimum filter value (MERV) 16 level filter pressure drop below the level of MERV10 filter. Compared with other commodities, filters, made by the excellent performance of portable media allows high efficiency air purifier air filter (HEPA) clean air output rate (CADR) increased by 10% to 30%; vacuum cleaners used by the newly developed filter media made of filter performance is greatly improved.

Air particulate matter and air purification

Have exact scientific data show a high degree of pollution of the environment can be a serious hazard to public health. The latest study showed that the concentration of particulate matter and mortality is proportional to the concentration of particulate matter in the higher life of people in cities than in cities with lower concentrations of particulate matter in the life of the people live shorter. Mortality and fine particulate matter concentrations. Apparent in the ambient air pollution, especially in the many city areas the smoke, causing the indoor air was considered higher than the surrounding air clean. However a large number of studies have shown that indoor concentrations of certain air pollutants than outdoor. According to the latest 20 years of scientific research, indoor air quality on human health problems have a major impact, such as the occurrence of headache, nausea and respiratory diseases and other ailments. Considering most people, especially infants and the elderly, in the indoor (or at home, school or in the workplace) of the time 80% to 90%, the cause of health problems increase the likelihood of indoor pollutants. Because each person every day 10 ~ 20m3 of air inhaled, respiratory aerosols and other particles of biological material and the deposition of the main entry port.

Indoor air pollutants in the air of harmful substances, ranging from particles to the organic / inorganic compounds, and radon gas, this article relates only to Part I: particulate matter (including bio-aerosol). Particles is used to describe a very small solid or liquid particles in terminology, the grain size of about 0.005 ~ 500 m. Each particle size, chemical composition and physical performance can vary. Atmospheric aerosol concentrations and indoor concentrations of particles are closely related. Based on this study can be drawn from the indoor air than outdoor air has a higher concentration of particulate matter conclusions. One activity in the air is relatively airtight buildings will increase the concentration difference. It was found, indoor and outdoor particulate matter size distribution similar, but the indoor submicron particles greater proportion. Indoor particulate matter can be outdoor air, smoke, fire, fireplace, resident activities, carpet, curtain and pet, etc. into.

Accommodation for smokers, indoor / outdoor concentration of respirable particles than the range of 1.1 to 4.4. It is clear that smoking is a major manufacturer of indoor particles, while other sources of indoor particles, such as cooking and cleaning, and indoor / outdoor particulate matter concentration ratio of different. Indoor pollution sources even in the smoke-free home is also likely to PM2.5 concentrations (particulate aerodynamic diameter
