Fisher & Paykel Chamber Seal for SleepStyle and SleepStyle+

The Chamber Seal is the small silicone component that keeps your SleepStyle or SleepStyle+ humidifier working as it should — maintaining a watertight seal on the water chamber so pressure stays where it belongs and your humidity therapy stays consistent through the night. This is the genuine Fisher & Paykel replacement part (MPN: 900SPS101), designed specifically for the SleepStyle and SleepStyle+ range.

Key Features

• Genuine Fisher & Paykel part — designed and tested for precise fit with SleepStyle and SleepStyle+ humidifiers, so you can trust the seal every night.
• Flexible silicone construction — soft, durable silicone conforms to the chamber rim cleanly, with no gaps that could let pressure or water escape.
• Removable from the chamber itself — the seal detaches fully from the chamber, eliminating hidden crevices where mineral deposits and mould can accumulate.
• Easy peel-back design — a simple peel-back action gives you quick access for topping up your water each day without wrestling with the seal.
• Dishwasher safe — clean thoroughly without any special handling required.
• Recommended replacement every 6 months — regular replacement maintains a reliable seal and supports good hygiene standards for your humidifier.

Who Is This For?

This chamber seal is suited to anyone using a Fisher & Paykel SleepStyle or SleepStyle+ CPAP  machine who has noticed their existing seal becoming stiff, discoloured, or no longer holding a firm fit on the water chamber. It's also worth replacing as part of a routine 6-monthly humidifier service alongside the Outlet Seal for SleepStyle and SleepStyle+.
