What is the difference between an efficient air filter and an efficient air filter? The reason why efficient filters and sub-efficient filters have these two statements is because the filter efficiency is different.The filter efficiency is not the same as the difference in the filter material.Of course, there is also a fixed-point difference in the filter production process.Different standards of use,The European standard is divided into three levels of junior high school efficiency,China's national standard has added two levels to it,That is, high efficiency and sub-efficiency.That is, there is no such thing as Asian efficiency.According to the grade standard,European label H10-H14 is efficient,U15 above is super efficient.The sub-efficiency in the national standard is equivalent to the H10 level.Some claims are covered by H10/H11.Since there is a difference in the grade Division,So in terms of filters,There are differences in filtration efficiency.The difference between each level is 10 times.In terms of

In the air purification system, how to write the management procedures for the primary, middle and efficient filters? First-effect air filter: Features: small resistance;Large air volume;Long service life.Scope of adaptation: suitable for primary filtration of air conditioning system.Medium-effective air filter, mainly used for capturing 1-Particle dust of 5 μm and various suspended solids,It is widely used in various air-conditioning equipment and air-conditioning systems,It is also used for intermediate protection of multi-level filtration system.The medium-efficiency filter is mainly used in central air conditioning and centralized air supply systems.It can be used for primary filtration of air conditioning system,To protect the next level of filters and the system itself,In places where the requirements for air purification and cleanliness are not strict,The air processed by the medium-effect filter can be directly transported to the user.Efficient filters are mainly used to capture 0.Particle dust an
