The part of a air filter that captures small dirt particles is the?

• A. Screen
• B. Element
• C. Core
• D. Seal

Answer: (B)

The filtration media inside the air filter—the element—is what captures small dirt particles. As air passes through the element, its fibers or pleated material trap dust and contaminants, preventing them from moving further into the system. The other parts have supportive roles: a screen can act as a protective mesh or pre-filter for larger debris, the core provides structural support, and the seal ensures a tight fit to prevent air from bypassing the filter. But the actual particle-capturing function comes from the element.
