Winter air of 32 degrees F. has capacity the amount of for only moisture that air of a temperature of 70 degrees has; therefore, there is a moisture shortage when the winter air is taken indoors and warmed to 70 degrees. The result is that Indoor air is too dry. The warm, dry air quickly dries the mucous membranes in the nose and throat, irritating them, creating of them more active fields for bacteria that cause disease. Furthermore, dry air is usually dusty air,.and more germs reach this active field for Infection The only practical solution of this un desirable condition lies in supplying the indoor air with sufficient moisture to offset the deficiency. This is best by means of modern accomplished warm air hearing systems of the vapor air type in which a humidifier that receives its water supply direct from the house main automatically Injects into the home air the moisture from 3 to 25 gallons of water per day, according to requirements. An average of six gallons of water per day, or one quart per hour, should be evaporated to offset the moisture deficiency in the house. average Trace Respiratory Diseases to Dust one-four- th SEASOOF COLDS Two a Year Average Person's Lot as Result of Dry Indoor Air.

Often, tunes can be distinguished at a distance of three miles. or ing winter is usually only less of what it should be for complete comfort and to conserve health. Au adequate supply of air moisture makes definite fuel savings possible, because it precludes the need for high temperatures to impart physical comfort. If the home air is adequately humidified, complete physical comfort Is assured at moderate temperatures of 72 degrees, or less. Heating engineers estimate that 10 and more of the average fuel bill is wasted In maintaining temperatures about 72 degrees. Proper humidification Is generally impossible with old style water pans and many other devices now on the market, according to the Institute engineers. Most of these devices, they state, are minus sufficient evaporating capacity and, in general, all have the common fault of Inefficient distribution. According to the Institute engineers, humidifiers should be of a special design, such as those in modern warm air systems of the vapor air type, the evaporating surface of which fosters rapid evaporation of large quantities of water and receives a constant water supply by pipe connection with the house water main. The need for devices of this sort, explain the engineers, is demonstrated by the fact that adequate humidification of the home air entails the evaporation of at least one to one and gallons of water per room per day. Fuel economies are also in order as a result of forced air circulation. This vital factor of air circulation prevents the formation of discomforting pockets d of air, moderately heated cool air, now characteristic and air, of the average home during winter. Air motion keeps the indoor thoroughly diffused and of practically uniform temperatures. Heating systems of the vapor air type, says the Institute engineers, are better referred to as systems. They warm the air, moisten the air and keep it In constant motion. The later phase of air conditioning Is performed by means of an unit, which effects the essential diffusion and distribution of the humidified, warm air. one-fift- h one-quart- er over-heate- Sunbeams Noticed When Air Is Dusty Sunbeams that pour In through the windows on cold, winter days, are not necessarily harbingers of good cheer and healthfulness, states the Holland Institute of Thermology, of Holland, were Michigan, which points out that of excessive quantities the it not for the beams home air, Id the dust ditioning systems now available are would not be visible.
