📊 The Efficiency of HEPA Filter
⚡ Efficiency Range: 99.9% — 99.999999%
Filters can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.
Filters can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.
For filters made of the same material, higher efficiency typically results in greater resistance and higher cost, while lower efficiency leads to reduced resistance and cost. Altering the air velocity will also affect resistance, efficiency, and the number of filters required, so appropriate selection should be made according to specific conditions.
⏱️ Service Life of Filters
As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.

❓ Frequently Asked Questions
Q What is the efficiency range of an Aluminium Foil Separator HEPA Air Filter?
The efficiency of currently available HEPA filters ranges from 99.9% to 99.999999%. The appropriate efficiency level should be selected based on specific application requirements, as higher efficiency generally comes with increased resistance and cost.
Q What materials are used in the frame of a HEPA filter?
The frame of a HEPA filter can be made from various primary materials, including Plywood, Aluminum Profile, Stainless Steel, and Galvanized Steel. The choice of material depends on the operating environment and customer requirements.
Q Why is aluminum foil used as a separator in HEPA filters?
Aluminum foil is the primary separator material because it effectively supports and secures the pleated filter media, ensures uniform airflow channels, and prevents media collapse under high differential pressure — all while being lightweight and durable.
Q How do I know when a HEPA filter needs to be replaced?
A HEPA filter should be replaced when the resistance (pressure drop) reaches an unreasonable or specified maximum level. Additionally, if there is a risk that previously captured dust has become dislodged and may re-enter the airflow, the filter should be replaced immediately to maintain air quality.
Q In which industries are Aluminium Foil Separator HEPA Filters commonly used?
These filters are widely used across multiple critical industries, including electronics and semiconductor manufacturing (clean rooms), pharmaceutical and biological engineering, ICUs and isolation wards, hemodialysis centers, food and beverage production, scientific research laboratories, and precision instrument assembly workshops.
Q Can HEPA filters be customized to specific sizes?
Yes. Custom sizing is supported to meet individual project requirements. The initial resistance tolerance is ±10%, and customers are welcome to specify their required dimensions. Please contact us for detailed specifications and quotations.
