Indoor Air Quality. How important is it? Indoor Air Quality is always a primary concern in commercial buildings but for some reason, it always seems to get overlooked in the residential market. It’s important to understand that installing a new system, if done correctly, will condition the air, meaning it will maintain desired temperatures and humidity. A new system will not completely CLEAN the air. Look around your home or office, if you see dust on counter tops, dressers or TV’s, or if you see dust in the air when sunlight comes in, then you are a prime candidate for an air cleaner. Keep in mind that without an air cleaner, all dust particles as well as every cough and sneeze, not caught by a traditional filter, will only be filtered by your lungs.
