G3 G4 Grade Pre Filter
G3 G4 Grade Pre Filter is a key filter in an air purifier. Its main function is to intercept large-sized dust, pollutants and other particles so that they cannot enter the interior of the air purifier. Therefore, the filtration grade and standard of the primary filter are crucial to the performance and quality of the air purifier.
Filtration level of primary filter
The filtration grade of the primary filter refers to the maximum size of particles that the filter can filter. Usually the filtration grades of primary filters are G1, G2, G3, and G4. Among them, G1 can filter particles with a diameter greater than 5 microns, G2 can filter particles with a diameter greater than 1 micron, G3 can filter particles with a diameter greater than 0.5 microns, and G4 can Filters particles larger than 0.3 microns in diameter. The higher the filtration level, the higher the filtration efficiency, but it will also increase the resistance of the primary filter and affect the performance of the air purifier.
Filtration standards of primary filter
The filtration standard of the primary filter refers to the filtration efficiency of the filter for particulate matter. The filtration standard is usually determined based on the filtration grade of the primary filter. For G1 grade primary effect filters, the filtration efficiency should not be less than 30%; for G2 grade primary effect filters, the filtration efficiency should not be less than 60%; for G3 grade primary effect filters, the filtration efficiency It should not be less than 80%; for G4 grade primary filter, its filtration efficiency should not be less than 90%.
Since the filtration efficiency of the air filter primary is related to the filtration grade, when selecting the primary filter, you should choose it according to actual needs. If you have higher requirements for filtration efficiency, you can choose a G3 or G4 grade primary filter.
Service life of primary filter
The service life of the primary filter depends on the concentration of particulate matter in the air and the filtration efficiency of the primary filter. When the concentration of particulate matter in the air is relatively high, the filtration speed of the primary filter will slow down and need to be replaced more frequently. Usually the service life of the primary filter ranges from 3 months to 1 year, but the specific service life needs to be determined based on factors such as the use environment and maintenance conditions.
Maintenance of G3 G4 Grade Pre Filter
In order to ensure the filtration efficiency and service life of the primary filter, regular maintenance and upkeep is required. Specific methods include the following aspects:
- Clean or replace the primary filter regularly;
- Clean or replace other filters of the air purifier regularly;
- Clean or replace the inside of the air purifier frequently;
- Regularly inspect and repair the air purifier;
- Avoid contact with humid environments and ventilate regularly.
The above is the relevant content of the filtration grade and standard of the G3 G4 Grade Pre Filter. The primary filter is a very important part of the air purifier and is related to the filtration effect of the entire air purifier. Therefore, when purchasing and using an air purifier, you must pay attention to the filtration grade and standard of the primary filter, select a suitable primary filter, and perform regular maintenance and upkeep to ensure the good performance and long-lasting use of the air purifier.
