The concentration of airborne microorganisms can be substantially reduced by passing air containing a concentration of microorganisms through a core of desiccant. Preferably, the core of desiccant is present in a moisture transfer wheel, which forms part of an open-cycle air conditioning system. The preferred desiccant is a large-pored crystalline titaniumsilicate molecular sieve, which can be regenerated into an essentially anhydrous state at a regeneration temperature of less than about 200 DEG F., and thereafter can absorb moisture from air to provide air having a vapor pressure of less than about 3 torr. |
