Review on Runclean Replacements Compatible Compare XHFFC600 by April Kahn

The black plastic part holding the white filter is loose on the motor in the chamber. Sit there freely. It should be pressed down slightly and fit snugly against the top of the motor to prevent dirty air from entering the motor and HEPA filter. Fit HEPA filters. I am sending it back as everything should fit! The parts are not identical.
