Today’s homes are built tighter than ever before. While this may be good for energy efficiency, tighter homes trap indoor air pollutants. Cleaning the air in a home is as important as heating and cooling it. Removing circulating dirt, dust, pollen and particulates from indoor air is a costly and irritating problem. Ordinary furnace and air conditioner filters remove only a relatively small amount of these airborne particles. Even the most sophisticated heating and cooling equipment is not designed to control indoor air quality. Investigate the Indoor Air Quality Products from Robertshaw^®. We carry Air Cleaners, Humidifiers, Ultraviolet Light Systems, Heat Recovery Ventilators and Energy Recovery Ventilators. These products can make a huge difference in cleaning indoor air and removing the many pollutants that can be present.
