Microbial medical gas filter, sterile, single-use

A microbial medical gas filter is a sterile, single-use device designed to remove microorganisms from medical gases such as oxygen, air, or anaesthetic vapours before they reach the patient. It is used during respiration, anaesthesia, or surgical procedures like insufflation to reduce the risk of microbial exposure and infection.

This category includes only small plastic housings containing a microbial filter that may also capture particulates like scale, with no additional intended functions beyond filtration. As a sterile, single-use device, it is intended for one patient encounter and must be discarded after use, with regulation based on its intended use and design as a barrier against microbial contamination in medical gas pathways.
