Resmed S9 H5i Standard Cleanable Water Chamber Tub - Durable CPAP Part

In this review the Resmed S9 H5i Standard Cleanable Water Chamber Tub is evaluated for CPAP users who need a straightforward, replaceable water chamber. The bottom line: this is a practical, cleanable chamber designed specifically for the H5i and Resmed S9 H5i setup, and its single biggest reason to buy is compatibility and ease of cleaning. The reviewer found it best suited to users who want a direct fit with known ResMed machines and prefer a reusable, simple water reservoir that integrates with their humidifier without extra accessories.

Key Features

• Compatibility: Made for the H5i and Resmed S9 H5i systems so it fits the humidifier housing without modification.
• Cleanable design: The chamber is built to be rinsed and dried between uses, helping maintain hygienic humidification over time.
• Replaceable part: As a standard tub it can be swapped quickly when showing wear or if a spare is desired, reducing downtime.
• Simple form factor: Its straightforward shape and construction make it easy to handle, fill and reinsert even in low light.
• Humidifier integration: Works with the device's humidification system to deliver consistent moisture during sleep therapy.

Who It's For

This water chamber is aimed at CPAP users who already own a ResMed S9 H5i or the H5i humidifier module and need an official-style replacement or backup part. It is useful for households that prefer reusable components and regular cleaning rather than disposable inserts.

It is not intended for people seeking universal chambers that adapt to a wide range of non-ResMed machines or users who require specialty features like anti-microbial coatings or integrated sensors; such buyers should look for alternative products designed with those extras.

Pros & Cons

Pros

• Direct fit for H5i and Resmed S9 H5i units, so installation is straightforward.

• Replacement availability reduces the need to run the humidifier without a tub if the original is damaged.

Cons

• Limited to H5i/S9 H5i compatibility, so it is not a universal CPAP water chamber.
