Electronic- or Media-Type Air Filters: Filtering the air within your home will help eliminate smoke, pollen, odor, dust mites and allergens. This will allow you to breathe easier, sleep better and enjoy your home more.

Whole-House Humidifiers: Whole-house humidifiers provide consistent humidity levels throughout the home, and some models even adjust the humidity level automatically. The average heated home has a humidity level of less than 20%. The recommended humidity level in the winter should be between 35% and 45%.

Air-to-Air Heat-Recovery Ventilators: These ventilator systems remove stale air from inside the home, while bringing in fresh air from the outside that is warmed during the transfer process.
