We have tested your Aranaire Electrical Air Purifier model KS and have observed that the unit prevents the formation of mold on fresh strawberries kept under ordinary household refrigeration. Berries kept without the unit in the refrigerator molded in three or four days to the point of 70 per cent destruction. On the other hand, berries kept well for 14 days when the unit was placed in the refrigerator. There was conciderable dehydration of the berries, but no mold formed. We find the Aranaire unit useful at least to prevent molding of strawberries in refrigeration.

We also feel that the unit may have other applications in the biology laboratory, and we will continue to investigate its further usefulness.
