    For most homes, the best solution is a type of ventilation device known as an energy recovery ventilator, or ERV. ERV combined with smart thermostat can control the temperature and humidity of the outside air brought into the house. Additionally, the ERV internal filter cleans the outside air as it enters, removing pollen and other pollutants. .
