Broan AVS K7 Energy Recovery Ventilator (ERV)  4"Side Ports  ERV70S

ERVs are suitable for all climates including those with hot, humid summers where homes are air-conditioned and possibly dehumidified during multiple seasons of the year.

Similar to the HRV, an ERV system recovers heat in the cold season but also recovers the energy trapped in moisture, greatly improving overall efficiency. In humid climates, where homes are air-conditioned and outside air is more humid than inside, an ERV system limits the amount of moisture coming into the home. In dry climates and humidified homes where humidity levels are greater inside, ERV systems limit the amount of moisture expelled to maintain optimal comfort levels.

The ERV air exchanging system improves recovery efficiency by recovering heat and retaining the energy trapped in moisture while also tempering your home with humidity-balanced fresh air. The result is better indoor air quality and comfort in your home. 

Balanced ventilation systems, if properly designed and installed, neither pressurize nor depressurize a home. Rather, they introduce and exhaust approximately equal quantities of fresh outside air and polluted inside air, respectively. 

A balanced ventilation system works within the home's HVAC system to facilitate proper distribution of fresh air throughout the living environment. Fresh air supply and exhaust vents can be installed in every room but are primarily focused to supply fresh air to bedrooms and living rooms where people spend the most time. It is also functional to exhaust air from rooms where moisture and pollutants are most often generated (kitchen, bathrooms, and perhaps the laundry room).
