How do I choose a central air conditioning air filter when it is vital?

First of all, we have to start with its key spare parts air filter, central air conditioning air filter should be understood, which refers to the system of indoor air filtration, usually used as a purification workshop, clean plant, laboratory, and clean room, or as a mechanical electronic, communication equipment, such as the role of purification of dust, according to the filtering effect, divided into the primary filter, medium-effect filter, high-efficiency filter and sub-high efficiency and other different According to the filtration effect, there are different types of filters, such as primary filters, medium efficiency filters, high-efficiency filters, and sub-high efficiency filters, etc.
All types of filters have different specifications and efficiency.



What we want to talk about here is the central air conditioning air filter, a high-efficiency filter also known as HEPA filter, which usually refers to a particle diameter greater than or equal to 0.3-micron particle capture efficiency of 99.97% above the filter, high-efficiency filter can be commonly used as electronic devices, pharmaceutical industry, medical institutions, food and other fields of general filtration, can also be used as a high-temperature resistant places.
High-efficiency filters are often used in semiconductor manufacturing plants, atomic power research centers clean rooms, laminar flow equipment, workstations, and other areas where very high cleanliness is required.



The use of filters should be controlled by the appropriate use cycle, in the absence of damage to the filter, the life of the filter is generally judged by the resistance, air conditioning unit high-efficiency filter is the core equipment of the air conditioning purification system, the filter to the formation of air resistance, with the filter dust accumulation increases, the filter resistance will increase with.
When the filter accumulates more dust, the resistance is too high, the filter ventilation is reduced, or the filter is partially penetrated, the resistance increases to a certain specified value, and the filter will be scrapped.
Therefore, the service life of the filter depends not only on its own merits, such as filter material, filter area, structural design, initial resistance, etc. but also on the dust concentration in the air, the actual air volume used, the final resistance setting, and other factors.
