A convective thermoregulation blanket (204) includes an exterior surface (220), a plurality of interconnected distribution channels (940, 941) and a first inlet opening (1244). A portion of the exterior surface is configured to be in contact with a patient. The interconnected distribution channels are located internal to the convective thermoregulation blanket and include a primary distribution channel (940) having an interior surface. The first inlet opening extends between the exterior surface of the convective thermoregulation blanket and the interior surface of the primary distribution channel to deliver thermal regulated convective air into the primary distribution channel. At least a portion of the primary distribution channel includes a filter material. The filter material filters unfiltered thermal regulated convective air in the primary distribution channel and provides the remaining plurality of distribution channels with filtered thermal regulated convective air.
