Abstract
In a double-bind crossover study in an office building without known complaints, enhanced particle filtration greatly reduced concentrations of submicron airborne particles and was associated with slight improvements in most questionnaire outcomes. However, chance effects could be excluded only for confusion, too stuffy, and too humid. Higher temperatures even within conventional comfort limits were related to significant worsening of many questionnaire outcomes.
