The Science of ComfortTM
A fan filter unit, or FFU, is essentially a filtered laminar flow diffuser with an integrated fan and motor.
The integrated fan and motor provide enough static pressure to overcome the pressure drop of the internally mounted HEPA or ULPA filter.

High-efficiency particle air filters, or HEPA filters, are used for air filtration where room particulate control is of the utmost importance, including in cleanrooms, laboratories, pharmaceutical compounding facilities, protective environment isolation rooms and airborne infectious isolation rooms.

Airborne infectious isolation rooms (AIIRs) are used for patients with easily communicable airborne diseases. When there is a shortage of AIIRs, existing patient rooms (or hotel rooms in temporary care facilities) can be converted to negative pressure isolation rooms. Price Fan Filter Units (FFUs) can be used in three configurations to retrofit these existing spaces.
