create fresh and healthy living environments by supplying filtered air
into a property at a continuous rate through ceiling mounted diffusers.
The diffusers are normally installed in a hallway or landing area.
The units have been developed to improve indoor air quality and resolve
condensation and mould problems and are designed to operate for 5
years with no requirement for maintenance other than replacement of
the filter. It is recommended that the filters are replaced after 5 years
usage.
