Lowenstein Prisma Breathing Tube 22mm (Non-Heated)

The Lowenstein Prisma Breathing Tube 22 mm (WM24445) is the genuine non-heated tube for Lowenstein Prisma CPAP and BiLevel machines. With universal 22 mm cuffed ends and a 19 mm inner diameter, it's a standard fit across the entire PrismaLINE range and most other major-brand CPAP devices — making it a reliable replacement, backup, or travel tube.

Key Features

• 1.8 m (180 cm) length with 22 mm cuffed ends: Universal CPAP/BiLevel connector size — fits the standard cuff connection on virtually all CPAP machines and masks.
• 19 mm standard inner diameter: Genuine Lowenstein airflow path — pressure delivery is identical to other standard 22 mm tubes.
• Lightweight ribbed flexible hose: Easy to manoeuvre on the bedside table and packs flat for travel.
• Genuine Lowenstein, latex-free: Part WM24445 — the same tube specified by Lowenstein for the Prisma range.

Compatibility

Compatible with the full Lowenstein PrismaLINE range — including the Prisma 20A Auto, Prisma SMART Max, Prisma SOFT Max, and Prisma 25ST BiLevel — as well as any other CPAP or BiLevel machine using the standard 22 mm cuff connection. Works with any standard CPAP mask.

Heated or Non-Heated?

Most Lowenstein Prisma machines ship with a PrismaHYBERNITE heated tube as standard, but the right heated tube depends on your specific Prisma model:

• Prisma 20A: Uses the integrated 15 mm PrismaHYBERNITE Slimline heated tube — powers directly from the device.
• Prisma SMART Max and SOFT Max: Use the 22 mm PrismaHYBERNITE Superday heated tube — powered by a separate cord.

This non-heated 22 mm tube is the lightweight alternative for users who don't experience rainout, a low-cost backup for travel, or a stand-in if your heated tube fails. It works on any of the Prisma machines listed above using the standard 22 mm cuff connection.

Cleaning & Care

Wash weekly in warm water with a mild detergent. Rinse thoroughly and air-dry out of direct sunlight. The tube is not autoclavable and should not be exposed to harsh chemicals or high heat.

When to Replace Your Tube

Replace your CPAP tubing every 6 to 12 months as part of standard maintenance. Replace earlier if you notice cracks, holes, persistent odour, or visible build-up inside the tube that can't be cleaned out.
