2. Humidification – HumidX & HumidX Plus

2.1. What is HumidX/HumidX Plus?

The HumidX technology is an optional waterless humidification system that captures heat and
moisture produced by the patient in the circuit to improve airway dryness symptoms common to
CPAP therapy. The HumidX provides convenient, small and low maintenance CPAP humidification.
Currently, the HumidX technology is available for the N20 series and AirFit P10 for AirMini masks,
offering two levels of humidification (HumidX and HumidX Plus) .

2.2. How does the HumidX work?

The optional HumidX technology is integrated in the AirMini tubing and allows exhaled air to pass
through the HumidX before reaching the mask vent. This configuration captures the heat and
moisture from the air and returns it to the patient upon inhalation. The operation of the HumidX
mimics the natural humidification processes of the nose to boost moisture levels when using CPAP
therapy. The ability to capture the patient's exhaled moisture before exiting the mask vent is designed
to provide an increased usability and breathing comfort.

2.3. Can the HumidX be cleaned?

No. The HumidX is a disposable component that cannot be cleaned or washed. The HumidX must be
replaced 30 days after the packaging is opened. The HumidX should be inspected daily, and replaced
if damaged or found with dirt or dust.

2.4. How often does the HumidX need to be replaced?

The HumidX must be replaced 30 days after the packaging is opened. If the HumidX was not used
every day during the 30-day period, it must still be replaced. The HumidX design life is based on the
date of opening the packaging not the number of days used during therapy.

2.5. What if the HumidX is used beyond 30 days?

ResMed does not recommend using the HumidX beyond 30 days. Although, the HumidX has been
tested beyond its design life, ResMed supports the safe use of 30 days. If the HumidX is used beyond
30 days this can cause deterioration in cleanliness, humidification performance and breathing comfort
which can affect safe and efficacious use of AirMini. The HumidX and other components of the
AirMini system are to be regularly maintained as per the user instructions.

2.6. Does the HumidX have a use by date?

No, the HumidX does not have a use by date and can be stored in the sealed packaging without
impact to the safety or efficacy of therapy. Note however that if the packaging has been opened,
damaged or torn at the time of receipt, the HumidX should be discarded and replaced with a new one.

2.7. Can I still use the HumidX if I got it wet?

No, if the HumidX gets wet (saturated) it is recommended to discarded and replaced.
