The U.S. Government (NIOSH) recommends that filtration systems be enhanced to remove hazardous air borne contaminants (See NIOSH Publication 2003-136). Uni-Guard is the most cost-effective enhancement method available.
The unique design of  Uni-Guard Ceiling Filter-Diffuser Units makes possible a revolutionary value-added concept in Air Filtration and Air Diffusion.
Uni-Guard ceiling filter-diffuser units enable high-efficiency, sub-micron filters to be applied in a central fan system at the room air supply outlets. This is the ideal location to provide maximum overall system filtration effectiveness without increasing fan energy costs. Uniform air motion within the occupied space "sweeps" contaminates to the filters and provides draft free thermal comfort at higher energy saving thermostat settings.
Uni-Guard ceiling filter-diffuser units are especially suitable for the enhancement of existing central fan filtration systems, but may also be used with new systems.
Installation of Uni-Guard ceiling filter-diffuser units is simple, replaces old conventional diffusers, and does not require modifications of duct work or equipment rooms. The units may be installed incrementally, over time, without shutting the system down.
Uni-Guard results can be measured immediately after the installation of a single unit. The occupants will see and feel the improvement.
