Whole-House-Quiet Fan

A whole-house-quiet fan allows an integrated approach to ventilating the bathrooms. The two-speed programmable unit operates at low speed, as programmed on a 24-hour timer, and at high speed when an individual timer is switched on. Because it ventilates all required areas at once, it provides more even ventilation and because it is totally quiet, those living in the house actually use its 24-hour capability. To enhance air quality, we sometimes also build an integrated system to filter and disperse the fresh replacement air.
