Heat Recovery Ventilators
Also known as Air-to-Air Heat Exchangers, HRVs are designed to provide balanced airflow while recovering up to 70% of the heat from exhausted air. A properly installed HRV help control moisture buildup that leads to mold, mildew and wood rot, while significantly improving indoor air quality.
Energy Recovery Ventilators
ERVs feature a heat exchanger combined with a ventilation system that captures up to 90% of the heat from stale indoor air that is exchanged for fresh outside air. An energy recovery ventilator with humidity regulation can remove excess humidity or add humidity to the ventilating air that is being brought into a house.
Air Filters
Standard air filters used with most forced-air systems are designed primarily to prevent large particles from damaging the furnace motor. Upgrading to filters that remove more of the particulate matter will improve the air quality of the home. Examples of these filters are extended surface, HEPA and electronic air cleaners. If you can get a high quality filter that is also washable and hence reusable, you are 2 steps ahead of the game.
Beware Formaldehyde in Air-tight Homes
One of the unforeseen downsides to having a well-insulated energy efficient home is the possibility for airborne toxins to have severe effects. One of these toxins is Formaldehyde. A well-ventilated home with air filters and live plants is not enough. You must be aware of products known to off-gas high concentrations of toxins such as formaldehyde. One of the main culprits in construction materials (and furniture) is pressed wood products. This includes plywood, particle board, paneling, and medium density fiberboards (very high formaldehyde concentration) used in some cabinetry. Other building materials to beware of are urea formaldehyde in fiberglass & foam insulation, some bamboo floors, gas stoves and paint.
