When people think about increasing the Indoor Air Quality of their homes, most probably think about pollutants like smoke/smog or allergens like pollen. Since these originate “outdoors”, the most logical thought is to close up your home as tight as possible and get an air cleaner of some sort. Although air cleaners like filters can and do help reduce the particles in the air to a varying degree, there is MORE to AIR quality than just “cleaning” the air.
The most critical and often overlooked aspect of having good indoor air quality is FRESH AIR. This, in it’s simplest form, is bringing outside air … inside. The first thought of objection might be that it seems counter-intuitive to bring air in that could have pollutants to try and “clean” the air, however, the EPA and other independant studies by AHRAE have shown that the pollutants like pollen can be 2 or 3x as high as outside air if a home is not properly ventilated.

A “properly ventilated” house includes both the intake of fresh air and the exhaust of inside air. Most homes come equipped with plenty of exhaust either in the bathrooms or kitchen vent hood but many do not have nearly enough intake of outside air. As a matter of fact, up until the 2000s, most homes were not equipped with any Fresh Air management at all which means that the only outside air that was coming inside was through cracks around doors and window. You might think this was an accident but it was actually “designed” this way because it has been know for 100 plus years that outside air is necessary for a healthy and clean air environment.
SmartZone-4X has a built-in FRESH AIR controller, that can be used to automatically (or manually) bring fresh air into the building. It was designed as a feature to meet the ASHRAE 62.2 standard but has many additional and useful features that make it more desirable than a standard “Fresh Air Control” like the Honeywell W8150.
Shown below, the SmartZone can be used as a “stand-alone” fresh air controller even without the need for any zoning.
