The AirSense 11 HumidAir water tub, available from CPAP Supplies Canada, is the genuine standard water chamber for the ResMed AirSense 11 heated humidifier. It is the part to order when your original tub is cloudy, cracked or building up mineral scale.

Why choose the AirSense 11 HumidAir water tub?

• Genuine 380 mL capacity. The chamber holds up to 380 mL, enough water for a full night of humidified therapy.
• Solid build. ABS plastic, a stainless steel base and a silicone seal stand up to daily use.
• Drop-in fit. It slides straight into the AirSense 11 humidifier bay with no tools.
• Fresh and hygienic. A new tub clears away the scale and film that build up over months.

Care and replacement

This is the standard tub, so hand wash it only. Wipe it out daily, and once a week wash it in warm water with a mild detergent, then air dry it out of direct sunlight. It is not dishwasher safe. Use distilled water to slow mineral buildup, and replace the tub every 6 to 12 months.
