Which of the following is NOT a characteristic of impingement filters?

Impingement filters are known for their unique mechanism of trapping particles, which is primarily based on the physical principles of inertia. One of their key characteristics is that their effectiveness is influenced by the size of the particles that they are designed to capture. Particles larger than a certain size are more effectively removed due to their inability to follow the airstream, which contributes to their capture on the filter media.

Another important aspect is that impingement filters rely on airflow velocity. The velocity at which air moves through the filter can significantly affect the filter's performance. Higher airflow velocities can increase the likelihood of particle capture, as particles have less time to respond to changes in the airstream direction and may collide with the filter media more effectively.

Additionally, the dust density can impact functionality. A higher concentration of particles can lead to a quicker accumulation of dust on the filter surface, potentially affecting the airflow and overall efficiency of the filtration process.

In contrast, the reliance on static electricity for filtration is not a characteristic of impingement filters. While some filters use electrostatic forces to enhance particle capture, impingement filters primarily depend on the physical interception of particles as they collide with the filter media. Therefore, stating that impingement filters rely on
