The HC300 Extended Life Humidifier Chamber is the durable, long-lasting replacement water chamber for Fisher & Paykel HC100, HC105, and HC150 series heated humidifiers. Designed to last for many years, this chamber is an upgrade from the standard HC325 water chamber that comes with the HC100/150 heated humidifier.
Built with sturdier materials than the standard chamber, the HC300 features a stainless steel base and high-density plastic dome that can be fully disassembled for efficient, thorough cleaning. The removable base makes it easy to eliminate mineral scale buildup that can degrade humidifier performance over time.
The chamber holds 15.2 ounces (approximately 450-480 mL) of water and has two ports located on the top of the dome for airflow connections. It can also be used on its own as an unheated, cold, or passover humidifier without the heated base.
The kit includes the HC300 water chamber, two chamber connectors, and one 24-inch inlet tube (900HC009), providing everything needed to replace or upgrade your existing humidification chamber.
Extended Life Construction — Built with a stainless steel base and high-density plastic dome for durable, long-lasting performance that can last several years with proper care.
Fully Disassembles for Cleaning — The base and dome separate completely, allowing thorough cleaning of all interior surfaces to remove mineral deposits and scale buildup.
15.2 oz Capacity — Holds approximately 450-480 mL of water with two ports on the dome top for airflow connections.
Versatile Use — Works with the HC100/150 heated humidifier base or can be used independently as an unheated, cold, or passover humidifier.
Complete Kit — Includes the water chamber, two chamber connectors, and a 24-inch inlet tube so you have everything needed for installation.
