Standard (ASMB 160)
Hypo-allergenic (Air Safety Electret100 – electrostatic filter)

Antibacterial filters

Antibacterial filters are not compatible with the ClimateLine or SlimLine tubing but can be used with the
Standard or 3m air tubing.
Antibacterial filters increase resistance in the air circuit and may affect accuracy of displayed and
delivered pressure, particularly at high flows. ResMed recommends using a filter with a low impedance
(eg, less than 2 cm H
30
O at 60 L/min).
