  1. High Efficiency Filtration: High Efficiency Fine Folding HEPA filters can effectively filter tiny particles in the air, including dust, pollen, bacteria, viruses, etc., to provide quality air purification. Its filtration efficiency usually reaches or exceeds 99.97%.
  2. Large Filtration Surface Area: The folded structure of the filter allows for a relatively large surface area, which increases the contact area of the filter surface with the air, thus improving filtration efficiency. This design helps to maintain high purification performance over time.
  3. Durability: High Efficiency Fine Fold HEPA filters are usually made of high quality materials, which gives them excellent durability. This ensures that the filter can maintain stable performance over time and reduce the frequency of replacement.
  4. Low Air Resistance Design: The reasonable design of the filter structure reduces the air resistance, ensuring that the air purification equipment can maintain good airflow during operation, without affecting the overall performance, and saving energy at the same time.
  5. Wide Range of Application: Due to its high filtration capacity, HEPA filters are widely used in various air purification equipment, including air purifiers, air conditioning systems, medical equipment and other fields.
    HEPA filters, with their high filtration efficiency, large surface area, durability, low resistance design and wide range of applications, have become an indispensable key component in modern air purification technology.

HEPA (High Efficiency Particulate Air Filter) is an air filtration efficiency level that can remove 99.97% or more of particles over 0.3 microns in diameter. HEPA filters are made of thousands of extremely fine fibers that can trap both smaller and larger particles.
They are very effective in removing particles from the air. HEPA filters are made of chemical fibers and glass fibers, which are randomly arranged to form layers of fine, irregular filters that cut off airborne particles of different sizes.
HEPA filters are classified as H10, H11, H12, H13, H14, and U15. Since different filters have different particle sizes, it is natural that they need to be replaced at different times.
When purchasing a filter, the filter specification will indicate the “Initial Pressure Loss”, which is the wind resistance of the new filter itself. As more particles are added to the filter, the air resistance will increase. Therefore, it is usually recommended to replace the filter when the air resistance reaches 2 to 3 times of the initial pressure loss of the filter.
Take our high efficiency HEPA as an example, at a specific airflow (different sizes will be tested at different airflows) the pressure loss is 250 pa right out of the factory, and when the pressure drop is closed to 500 Pa, it shall be replaced. (9.8 pa = 1 mm water gauge)
