VENTILATION

By DR. SAMUEL G. DIXON,

Commissioner of Health of Pennsylvania. The question of proper ventilation during the winter months is one which

it is quite difficult for many people to solve. It is apparent to almost body that the admission of pure air is necessary if efficient work is to be performed in office . and school and if rerefreshing sleep is desired by night. Tile fresh air does not de-

pend upon the temperature and can be supplied by a proper heating ami ventilating system. The opening of windows while it admits the fresh air, often causes drafts which are uncomfortable, not to say injurious. Where a number of people are occupied in a room it is often a cause of’subjecting one or two to exposure if the windows are opened to secure ventilation. This can be avoided by an ample supply of warmed air. Numerous devices, more or less expensive, have been placed on the market but are not always satisfactory. The most economical and at the same time probably the most efficient ventilating device is one made of glass or wood eight or ten inches in height and made the width of the sash. This should be placed under the sash with a slant from the bottom to at an angle of 45 degrees, leaving an opening at the top covered with cheese clotfi; Ventilators of this sort are so simple that they can be made at small co.<rt anywhere and the covering can be readily replaced. They are suitable for office anti school room, living rooms and bed rpoins,. They permit, reasonable ventilation without too great a loss of heat and prevent thht stuffiness of atmosphere-whieh is dangerous to health and destructive to real comfort during the winter months. This device leaves am.opening 'between the upper and lower sasli through which the used air of the room may escape.,’ ” f 7 #
