How to Select Appropriate Filter Media for Medical Equipment (e.g., Ventilators, Oxygen Concentrators) to Achieve High Filtration Efficiency and Low Airflow Resistance?
I. Core Material Selection: Balancing Efficiency and Low Resistance
PP Melt-Blown Filter Media
Utilizes an electrostatic charging (electret treatment) process, achieving >99% filtration efficiency for particles ≥0.3μm (e.g., bacteria, droplets). However, it exhibits a relatively high initial resistance (>20 Pa).
PP Electret Cotton (Triboelectric PP Media)
Employs a triboelectric charging process, delivering >99.99% filtration efficiency for particles ≥0.3μm (e.g., bacteria, droplets). Maintains a low initial resistance (15-30 Pa), achieving an optimal balance of high efficiency and low airflow resistance.
II. Technical Solutions for Optimizing Low Resistance Design
Expand the filtration area by employing pleated filter cartridges or increasing the pleat depth of the filter media. This design significantly reduces airflow velocity by 50%, resulting in a 30%-40% reduction in airflow resistance.
