An important component of breathing systems is the filter which protects the patient, the equipment and the breathing system from contamination. There are several types of filters available depending on the application of use. HealthTrust members have exclusive access to a respiratory breathing system filter matrix document. It can be found on the COVID Resource page and within the contract packages on the Member Portal. If you do not have access to the Member Portal, contact your local supply chain administrator or HealthTrust Account Manager to request a copy of the product feature summary document.
