No Water. No Condensate.
No Compromise.
The RespirAqTM Active Humidifier System delivers active heated humidification in a compact HME-scale design, eliminating the need for an external water supply and reducing complexity at the point of care.
Costly & inadequate humidification for ventilated patients.
Today's humidification solutions often require clinicians to choose between costly active heated humidification systems with complex water management or compact passive devices that may not meet humidification needs. More than 15 million patients require ventilation each year, with around 75% experiencing circuit condensation¹. Managing condensate costs hospitals an estimated $1.5 billion annually2, compelling clinicians to prioritise condensation management over direct patient care.
The result is a persistent trade-off between performance, simplicity, and workflow efficiency.
Condensation interrupts clinical workflow
Inadequate humidification increases complications
VAP adds ~$25k (USD) per patient in added costs2

Operates without an external water supply, eliminating condensate and the need for heated circuits.
Humidification Solutions Compared.
RespirAq bridges the gap between passive humidification convenience and active humidification performance, the convenience of passive humidification and the performance of active humidification, delivering a streamlined system design intended for adoption across care settings.
Smart Material.
Smarter Humidification.
The system operates through a three-stage process that begins during exhalation, when its patented thermo-responsive smart material captures moisture directly from the patient’s breath. Once sensors detect inhalation, they trigger a heating element to warm both the material and the incoming gas, causing the material to change state. This transition releases the captured moisture back into the breathing circuit, effectively conditioning and warming the inspired gas towards body temperature for the patient.

Exhale
Smart material absorbs moisture from the patient’s exhaled breath, capturing humidity that would otherwise be lost or cause condensation.
Inhale
Controlled heating releases the stored moisture and heat back into the inspired air, delivering optimal humidification with zero water supply.
