The QuFRESH QFDC (Patent, no. 11,079,126 and 11,306,932) offers homebuilders and developers a cost-effective mechanical ventilation solution that helps with humidity and temperature. Contractors and builders now have a practical offering for introducing constant fresh air from outside into the residence, meeting the fresh air CFM requirements. Internally mounted sensors provide limits preventing the intake of outdoor air that is too humid and/or hot or too cold and/or dry. The operator simply dials in the quantity (CFM) of fresh air needed from the quiet fan and sets the desired intake levels for the outside humidity and temperature. This fresh air fan can accept a 10" x 10" x 2" air filter up to MERV 16 for incoming air quality.
