Fresh air is essential for our health and well-being. In wintertime, this can be especially important, as we close windows and doors and turn on the heating. Even if the air quality outside your home is out of your control, you can make the air inside your home fresh and clean with a few simple actions. Your heating, ventilation, and air conditioning system keeps the air moving, but you need to maintain the HVAC properly. Consider other simple actions, such as buying a range of houseplants and moving the furniture to keep your indoor air clean, healthy, and fresh.
