Abstract
A door safety latch for air cleaner is provided. The door safety latch includes a latch arm including a latch projection, with the latch arm configured to pivot with respect to a door of the air cleaner, and a slider that traps a portion of the latch arm. The slider is configured to hold the latch arm in a first, latched position and further configured to pivot the latch arm to a second, unlatched position. The door safety latch further includes a release button that includes a stop shoulder. The release button is biased to a normally extended position with the stop shoulder blocking movement of the slider and the latch arm to the second, unlatched position.
