Reduce the risk of infection AND hypothermia with FilteredFlo blankets from CSZ. For use before, during and after surgery, they filter the air before it comes into contact with patients. This minimizes the spread of possible contaminants. Combine FilteredFlo blankets with CSZ's WarmAir warming system to quietly and effectively maintain normothermia. WarmAir's compact and lightweight frame makes moving the system easy. High and low temperature alarms help keep patients safe.
