Air filters include a composition which has a biostatic or biocidal agent adapted to migrate through particulates accumulating in use on the filter. The biocidal agent may have bacteriostatic and/or fungistatic properties and may optionally include a humectant, a surfactant or rheological additive. Compositions for treating filters and methods of reducing airborne contaminants in the air are also disclosed.
