AbstractPollen, mold, and bacterial determinations were made over a 4 month period from June to October in two houses, one of which was equipped with a central air-conditioning system. These determinations were compared to each other and to similar determinations made outdoors. A “rotoslide” pollen counter gave the most reliable and reproducible results. Central air conditioning markedly lowered the pollen counts during the ragweed pollen season in comparison with the home with no air conditioning and to outdoors. A highly allergic individual residing in the air-conditioned house had less symptoms during the season than a comparable allergic individual residing in the control house.
