Original Criti-Clean FFU

We still sell and support our original Criti-Clean fan-powered laminar flow HEPA filter diffuser (although it has a slightly lower maximum output and larger plenum height than the upgraded Criti-Clean Ultra). Our original units are still running strong in hospital operating rooms and other critical environments across America and around the world, continually delivering a non-aspirating, low velocity, uniformly distributed, downward moving “piston” of HEPA-filtered air.

Optional Features:

  • Built-In LED Lights – eliminate the need for additional light fixtures, help maximize the use of ceiling space and do not interfere with the airstream like hanging lights.
