Ease of use describes the relative ease of operating the air purifier including general operation and the air filter replacement process. The air flow is a measure of the amount of air that is effectively pushed through the air purifier. This is one of the best metrics used to determine the size of the room the air purifier can clean. The final measurement is the air filter efficiency. This is a rating of the percentage of airborne particles that are removed by the air purifier with each air passage.
