Philips Respironics Air Inlet Particle Filters for EverGo Portable Concentrators (DISCONTINUED)

USAGE: Respironics recommends washing filters on at least a weekly basis in a solution of warm water and mild liquid dish detergent. Filters must be completely dry prior to insertion into the concentrator case. If the filter appears damaged or dirty it should be replaced.
