How to choose the efficiency level of medical primary air filter

Medical primary air filter g3 and g4 efficiency In the initial effect of this efficiency is commonly used, the main difference is the difference in filtration efficiency and resistance. G3 primary effect filter is suitable for places with low air quality requirements, and can trap 85% of particles with a diameter greater than 5 microns; The G4 primary effect filter is suitable for places with high air quality requirements, and can retain 90% of particles with a diameter greater than 5 microns, and the specific use is different.

When selecting the appropriate grade of medical primary air filter, the following points need to be considered:

1, air quality requirements: according to different places and applications, the requirements for air quality are different. If the air quality requirements are high, it is recommended to choose G4 initial effect filter; If the requirements for air quality are general, you can choose aluminum alloy initial effect filter;

2, environmental pollutants: according to the actual situation, consider the type and concentration of pollutants in the air. If the environment contains more particles, it is recommended to choose G4 initial effect filter to ensure better filtration effect; If the concentration of particulate matter in the environment is low, you can choose the G3 primary filter.

3, economic cost: The price of high efficiency filters is usually higher, choosing the appropriate grade of the first effect filter can reduce the cost of replacement and maintenance. Make choices based on your budget.

The medical primary air filter grade is particularly important for ensuring air quality and maintaining economic costs.

According to the actual needs, choose the appropriate grade from the G3 and G4 primary filter to provide more air filtration effect.
