When I was searching for the perfect water chamber for my Resmed Airsense 11, I realized how important it is to choose the right one to ensure comfort and proper machine function. Here’s what I learned from my experience that might help you pick the best water chamber for your device.

Why the Water Chamber Matters

The water chamber in the Airsense 11 is crucial because it holds the distilled water that humidifies the air you breathe through the CPAP machine. I found that using the right chamber helps prevent dryness in my throat and nose, making therapy much more comfortable.

Compatibility Is Key

First, I made sure the water chamber was specifically designed for the Resmed Airsense 11. Not all chambers fit perfectly or seal well, which can lead to leaks or improper humidification. The official Resmed Airsense 11 water chamber is tailored to fit snugly into the machine.

Material and Durability

I looked for a chamber made of durable, BPA-free plastic that can withstand daily use and frequent cleaning. The Resmed chamber is made from high-quality materials that don’t crack easily, which gave me peace of mind knowing it would last a long time.

Ease of Cleaning

Cleaning the water chamber regularly is vital to avoid mold and bacteria buildup. I preferred a chamber that is easy to remove and clean. The official Resmed Airsense 11 chamber is dishwasher safe on the top rack, which made my routine hassle-free.

Capacity and Humidification Levels

The chamber holds about 325 ml of distilled water, which I found sufficient for a whole night’s therapy without needing a refill. This capacity supports adjustable humidification levels, so I could customize the moisture output to my comfort.

Replacement Frequency

From my experience and recommendations, it’s best to replace the water chamber every 6 months to maintain hygiene and machine performance. Even with careful cleaning, wear and tear can affect the chamber’s function over time.

Price and Availability

I compared prices from various suppliers and found that buying the genuine Resmed water chamber may cost a bit more but guarantees quality and compatibility. Avoid cheap knock-offs as they might not fit well or last long.

Final Thoughts

Choosing the right water chamber for my Resmed Airsense 11 made a significant difference in my CPAP therapy comfort. I recommend sticking to the official water chamber for the best experience, ensuring your machine runs smoothly and your therapy stays effective.
