As a world leader in tracheal and endotracheal closed suction systems, we offer Heat and Moisture Exchangers (HMEs), Filtering Heat and Moisture Exchangers (HMEFs), and Filters designed with the same quality as our KIMVENT* Closed Suction Systems. Our HMEs enhance humidification, our HMEFs humidify and filter, and our filters help provide filtration of bacteria and viruses. All three devices are designed to help ventilator-dependent patients in critical care and anesthesia.
