The primary filter is a common air filter, which is mainly used to remove large particles and dust in the air purification system, and is an important line of defense, which can effectively reduce the amount of pollutants in the air, thereby protecting people's health and comfort.
Primary filters work by physically screening particulate matter from the air. It is typically woven from one or more layers of fibrous material that traps airborne particulate matter and prevents them from entering subsequent filters or air conditioning units in air purification systems. Its screening efficiency can be adjusted according to the demand, and can generally reach more than 80% of the particulate matter capture efficiency. Primary filter The primary filter has a wide range of applications, including commercial buildings, medical institutions, industrial workshops, residences, etc. In commercial buildings, primary filters are usually installed in the air handling units of air conditioning systems to filter large particles and dust, protect the normal operation of air conditioning equipment, and provide good indoor air quality. In medical institutions, the use of primary filters is particularly important, which can effectively remove bacteria, viruses and other microbial particles and reduce the risk of cross-infection.
Choosing the right primary filter is critical to providing good indoor air quality. First of all, we should consider the filtration efficiency and choose the appropriate filtration level according to the actual needs. The second thing to consider is the size and installation of the filter to ensure that it can be used with air conditioning equipment or air handling units. In addition, it is also necessary to consider the life and replacement cycle of the filter to avoid the deterioration of the air purification effect caused by the use of expired filters for a long time. To ensure that the filter is working properly, regular cleaning and replacement are also key.
In addition to primary filters, there are other types of air filters that can improve indoor air quality. High-efficiency filters, for example, have higher filtration efficiency and are able to capture smaller particles and microorganisms. These HEPA filters are often used in places with high air quality requirements, such as operating rooms, laboratories, etc. HEPA filters are widely used in various air purification equipment, which can effectively remove harmful substances from indoor air.
Primary filters are an important part of protecting people's health and providing a comfortable indoor environment. By physically screening particulate matter and dust from the air, the primary filter can reduce the amount of pollutants and protect the normal operation of air conditioning equipment. In order to ensure that it works properly and effectively, it is crucial to choose the right primary filter and clean and replace it regularly. At the same time, indoor air quality can be further improved by combining other types of air filters.
