Product Description
The core of the Close Pleat HEPA Filter lies in its porous filter media, typically made of ultra-fine glass fiber or PP fiber paper.
As air passes through the filter, particles are intercepted, adsorbed, and filtered within the microscopic pores of the filter media.
The close-pleat design ensures smooth airflow, enhances filtration efficiency, and maintains uniform air velocity, further improving overall performance.
The filter frame is usually made of lightweight and durable aluminum alloy, facilitating easy installation and maintenance.
