More holes can provide more filtering channels, so that the sintered felt can more effectively capture and filter particles, dust or other impurities in the air, thereby improving the filtering effect. The porous structure can reduce the resistance of air when it flows through the sintered felt, thereby reducing energy consumption. By increasing the ventilation holes, the air can pass through the sintered felt more easily, reducing the pressure and energy required for the system and reducing the operating cost. The porous structure can increase the air permeability of the sintered felt and promote the flow of air, which helps to improve the ventilation effect of the system, make the air fresher, reduce the retention of moisture or odor, and improve the environmental comfort.
