According to the EPA, indoor air is 5 times more polluted than the outdoor air. To help provide fresh air to your home choose an air exchanger that will meet your needs.
The climate conditions where you live will determine whether you need a Heat Recovery Ventilator (HRV) or an Energy Recovery Ventilator (ERV). HRV's are usually recommended for colder climates with longer heating seasons. ERV's are used for warmer, more humid climates with long cooling seasons. Please see our helpful reference map to assist in selecting the right unit for you.
