Grainger has air filters for industrial and consumer applications to clear the air. Install a permanent electrostatic air filter that needs no hookup and generates its own charge. Purchase a hospital-grade, UL Class 1 HEPA filter with 95 percent efficiency that eliminates potential air leaks. Or, for fume and odor removal, choose a carbon filter set that is disposable, eliminating the need for refilling. Grainger has air filters that help you keep indoor air clean, comfortable and safe.
