HEPA air filter for clean and healthy air
HEPA filter (High Efficiency Particulate Air Filter) applies to any device capable of filtering. HEPA filters can capture at least 99.97% of particles with a diameter greater than or equal to 0.3m. They can filter out impurities and particles in the air, such as viruses, respirable dust, mites eggs and excretions, mold, dust, allergens, pollen, bacteria, dust mites or cigarette smoke, asbestos, various toxic dusts and aerosols from the air, dander, allergens from the fur of dogs or cats.
Here are the different levels of HEPA filters: (The higher the number following "HEPA", the higher the level of filtration is optimum.)
- HEPA H14: pass up 0.005% of 0.1 micron particles per liter of air.
- HEPA H13: pass up 0.05% of 0.1 micron particles per liter of air.
- HEPA H12: pass more than 0.5% of 0.1 micron particles per liter of air.
- HEPA H11: pass a maximum of 5% of 0.1 micron particles per liter of air.
- HEPA H10: pass more than 15% of 0.1 micron particles per liter of air.
- Thus, a more optimal filtration will need a more efficient model ( H14 or H13).
The HEPA filter is made from fiber glass or filter paper and form mini folds to increase the filter surface. It has the ability to retain the microparticles with a scattering effect, it captures particles and slows inertia. It has large filtration area, the proven high quality and performance even in difficult environments.
HEPA filter application:
They are used in the medical field, in hospitals (such as operating rooms, intensive care units and laboratories and clean rooms, analysis laboratories), the chemical and pharmaceutical companies, electronics companies, aerospace, in the nuclear industry and in some air scrubbers. HEPA filters are used as filtering element in vacuum cleaners and air conditioners. They have the ability to form a laminar or turbulent flow of sterile air when used in pharmaceutical processes of sterilization.
Today, HEPA filters are also used in homes and offices because people are more concerned with clean air. This has led to increased demand for such devices. These types of air filters are made in air purifier, office equipment filters, industrial vacuum cleaner filters, medical equipment filters, car engines, and smoke/fume exhaust filters.
HEPA filters prevent the spread of bacteria and viruses through the air and, therefore, are very important to prevent infection. HEPA filtration systems for medical purposes usually incorporate high-energy ultraviolet light to eliminate any live bacteria and viruses trapped by the physical filter. Some of the best rated HEPA units have an efficiency of 99.995% which ensures a high level of protection against diseases that are transmitted through the air.
Use on planes
Modern aircraft use HEPA filters to reduce the spread of pathogens through recirculated air. These microbes such low levels are due to the complete change of air within the cabin conducted between 10 and 15 times per hour and the high capacity filtration systems air recirculation. These filters used in common planes are similar to HEPA filters used in industrial clean rooms and critical wards of hospitals.
Clean room filter
Fan unit that employs a HEPA filter precision air-conditioning equipment in the clean booth and clean room, for incorporation manufacturing equipment is used. It is suitable for semiconductor and liquid crystal, such as medicines and foods corresponds to the range from 100 to 10,000 cleanliness class, such as those requiring high cleanliness.
Air cleaner filter
Thing using the HEPA filter has many high-end models of fan type air cleaner has become the mainstream of current.
Household vacuum cleaners filter
Thing using the HEPA filter has many high-end models among household vacuum cleaner.
Nuclear facility exhaust filter
In nuclear facilities, when discharged from the exhaust plants as a gaseous waste, HEPA filters are used to remove the radioactive particles in the exhaust air ventilation after.
Note: change the HEPA filter every 12 months to ensure optimal air cleaner.
