HumidAir 11 Cleanable Water Chamber ResMed AirSense 11

The HumidAir 11 Cleanable fits ResMed AirSense 11 AutoSet, Elite and AutoSet for Her devices. It is not compatible with AirSense 10 (which uses the HumidAir II), AirCurve 10 or AirMini. Verify your model before purchase.

The Cleanable version fully disassembles and is dishwasher safe (max 55°C). It lasts several years with proper care. The Standard version is hand-wash only with a shorter lifespan. Cleanable is the durable option for everyday use.

With proper care, expect a lifespan of 12 to 18 months. Replace the chamber if you see cracks, embedded scale, black mould spots or persistent odours after washing. Hard water shortens lifespan: prefer distilled water.

Empty the chamber every morning and rinse with clean water. Once a week, disassemble and wash with warm water and mild detergent. The Cleanable is dishwasher safe (top rack, max 55°C). Disinfect monthly with a vinegar-water solution (1:1).

Distilled water is strongly recommended: no scale, no minerals, no premature wear. Tap water is tolerated if you have no alternative, but it leaves deposits that shorten chamber life and may affect air quality.

Lift the front cover of your AirSense 11. Slide the HumidAir 11 chamber into its slot until it clicks. The machine automatically detects the humidifier and activates the matching menu. Fill with distilled water to MAX line before each night.

Not mandatory, but very useful against nasal dryness, dry mouth on waking and congestion. Most CPAP patients consider it essential. Paired with the ClimateLineAir 11 tube, it activates Climate Control for maximum comfort on AirSense 11.
