Hypoallergenic filters for AirSense 10 and S9 (Pack of 12)

Hypoallergenic filters are better suited to trap fine particles that can infiltrate your unit, and ultimately harm your respiratory system. These filter types are not included with the purchase of a CPAP unit, and can be added afterward to offer a better protection against different allergens found in the ambiant air. The manufacturer recommends changing the filter every month for a better protection of your respiratory system and the unit itself.  Never use more than one filter at a time. Do not wash with water or soap.
