Use only room temperature distilled water. Tap water may cause mineral buildup and damage. Avoid adding essential oils, perfumes, or chemical additives—these can degrade chamber materials and impact therapy effectiveness. Do not overfill past the maximum fill line, as this can lead to water leaks or damage to your machine. Built-In Replacement Reminders If you’re using a ResMed AirSense 11 device, you can activate the Humidifier Set function to get regular reminders when it’s time to replace your water chamber. However, if you notice any cracks, discoloration, or leaks before that time, replace the chamber immediately. Cleaning & Maintenance Guidelines Daily: Empty any remaining water after each use. Wipe the chamber dry with a clean, disposable cloth. Store away from direct sunlight. Weekly: Wash by hand using warm water and a mild detergent. Rinse thoroughly and allow to air dry fully before reuse. Do not wash in the dishwasher—this standard model is not dishwasher safe. Important Usage Warnings Never run your humidifier without the water chamber installed. Do not attempt to fill the water chamber while it’s installed in the device. Avoid transporting your humidifier base with water inside the chamber. Always remove and empty the chamber before travel.
