We re-designed and re-engineered our popular Criti-Clean fan powered laminar flow HEPA filter diffuser to maximize both CFM and energy efficiency. Our new Criti-Clean Ultra has the highest CFM output on the market (up to 1100 CFM for our 48″x24″ model), is more energy efficient (only 42 watts at 90 FPM velocity/ 450 CFM), and is incredibly quiet (only 45 DBA at 90 FPM, 58 DBA at 1100 CFM). Plus, the new unit has all the same great features and options as the original.
