Combined filter/HME reduces set up time
Electrostatic hydrophobic membrane protects against cross-contamination
Hygroscopic membrane traps patient's moisture providing effective airway humidification
Low resistance to airflow minimizes work of breathing
Effective moisture control reduces the risk of colonization in breathing tubes and minimizes sampling line blockage
End tidal CO2 sampling port offers convenient access to airway gases; treated with physiologically safe calcium chloride
