ResMed's H4i Integrated Heated Humidifier offers some major improvements on the original HumidAire 3i that bring even greater simplicity and more comfort. With 30% more humidity, the H4i really helps sooth dry mouth and nasal irritation that can sometimes be caused by CPAP therapy. Research proves that the warm, moist air humidification provides helps relieve symptoms of dryness and makes sleep therapy more comfortable.

The H4i clicks easily into place for seamless integration and supports ResMed’s full S8 platform including the S8 Compact, S8 Escape/Escape II, S8 Elite/Elite II, S8 Vantage, S8 AutoSet II, VPAP S, VPAP ST, and VPAP Auto/Auto 25. The compact design is unobtrusive in the bedroom and easily packed for travel.

The ResMed H4i offers user-friendly humidity control with a dial that’s easy to read in the dark, and it’s quick to respond to any adjustments you make. It also has greater water capacity that supports humidification needs at higher flow rates and pressures, and a convenient flip top lid that makes it easy to refill.

    This heated humifier is excellent, as long as it works. The problem is that the water container breaks after 6 weeks of nightly use. The retaining ring on the bottom cracks (from heat?) and then it leaks, making it unuseable. Insurance will only pay for replacements every 6 months, so I am left to my own innovations for 4, 1/2 months at a time. Highly unsatisfactory.
