GuardianPlus Fresh Air Ventilation and Energy Recovery System

The GuardianPlus HEPA Filtration with Fresh Air Ventilation and Energy Recovery from Broan-NuTone transfers both latent (moisture) energy and sensible (temperature) energy from opposing air streams, heating/cooling incoming air and minimizing incoming humidity. The fresh air reduces the presence of contaminates smaller than 0.3 microns while the HEPA filtration removes pollens, dust, mold spores, and pet dander.
