<p>To be effective, you will want to fine tune the motor speed to a medium setting. This allows smoke contaminated air to be in contact with the carbon longer. Dwell Time is the amount of time contaminated air is in contact with the carbon. Increasing the dwell time increases the efficiency of toxic gas adsorption.</p> | <p>To be effective, you will want to fine tune the motor speed to a medium setting.
