Air Filter Media: Differentiating Filtration Levels

Air Filter Pad plays a crucial role in ensuring clean and healthy air in various settings, ranging from residential homes to industrial facilities. The effectiveness of air filter cotton largely depends on its filtration等级, which determines the type and size of particles it can capture. Here's an overview of the different filtration levels of air filter cotton:
Coarse Filtration (G1-G4)
Coarse filtration Aquarium filter media is the most basic level, designed to trap large particles such as dust, pollen, and pet hair. These filters are commonly used as a pre-filter in air conditioning and ventilation systems to protect more advanced filters from getting clogged quickly. The filtration efficiency of G1-G4 filters ranges from 20% to 70% for particles larger than 5 microns.

- G1 (Least Efficient): Removes the largest particles, typically used in areas with high dust concentration.
- G2: Offers slightly better filtration than G1, suitable for general residential and commercial applications.
- G3: Captures more particles than G2, often used in hospitals and clean rooms.
- G4: The most efficient in the coarse filtration category, used in environments requiring higher air quality.
Medium Filtration (F5-F9)
Medium filtration air filter cotton provides a higher level of filtration compared to coarse filters. These filters can capture smaller particles such as mold spores, bacteria, and some viruses. F5-F9 filters are commonly used in residential, commercial, and light industrial settings.
- F5: Captures particles larger than 1 micron with an efficiency of 40% to 60%.
- F6: Removes particles larger than 1 micron with an efficiency of 60% to 80%.
- F7: Offers filtration efficiency of 80% to 90% for particles larger than 1 micron.
- F8: Filters out particles larger than 1 micron with an efficiency of 90% to 95%.
- F9: The most efficient in the medium filtration category, with a filtration efficiency of 95% for particles larger than 1 micron.
Fine Filtration (H10-H14)
Fine filtration air filter cotton is designed to capture even smaller particles, including fine dust, tobacco smoke, and most viruses. These filters are commonly used in hospitals, laboratories, and other environments where high air quality is essential.
- H10: Captures 95% of particles larger than 0.3 microns.
- H11: Offers a filtration efficiency of 98% for particles larger than 0.3 microns.
- H12: Filters out 99.5% of particles larger than 0.3 microns, commonly used in clean rooms.
- H13: The most widely used fine filtration filter, with a filtration efficiency of 99.95% for particles larger than 0.3 microns.
- H14 (HEPA): The highest level of filtration, capturing 99.995% of particles larger than 0.3 microns, used in critical environments such as operating theaters and pharmaceutical manufacturing facilities.
Ultrafine Filtration (U15-U17)
Ultrafine filtration air filter cotton is the most advanced level, designed to capture the tiniest particles, including nanoparticles and aerosols. These filters are commonly used in specialized environments such as semiconductor manufacturing and research laboratories.
- U15: Captures 99.999% of particles larger than 0.1 microns.
- U16: Offers a filtration efficiency of 99.9995% for particles larger than 0.1 microns.
- U17: The most efficient ultrafine filtration filter, with a filtration efficiency of 99.99995% for particles larger than 0.1 microns.
In conclusion, the choice of air filter cotton depends on the specific requirements of the environment and the level of air quality needed. From coarse to ultrafine filtration, each等级 offers unique benefits and is designed to capture different sizes of airborne particles.
