Many homes and offices are filled with dry, stagnant, overheated air during winter. This unhealthy environment promotes dry, itchy skin, nosebleeds, sleeplessness, respiratory problems, headaches, asthma attacks, static electricity, and general discomfort. The Convairâ„¢ 3-in-1â„¢ works to help eliminate these problems by moisturizing and cleaning the air, circulating moist, refreshed, healthy air throughout a home or office while balancing the temperature in uncontrollably hot and uncomfortable spaces.
