$1,999.00 $2,799.00

The Loewenstein Prisma 20C represents the pinnacle of precision sleep apnoea therapy, combining state-of-the-art technology with superior comfort and flexible connectivity. Originally designed as a hospital-grade ventilator, this device offers the durability and reliability needed for continuous, 24/7 use. It features a hand-balanced, Swiss-engineered blower motor for optimal performance, ensuring whisper-quiet operation and precise pressure delivery.

The Prisma 20C operates at a set fixed pressure level, clinically prescribed and set by your healthcare provider, set from a pressure range of 4-20 cmH2O. Unlike automatic machines, the Prisma 20C delivers consistent, fixed-pressure therapy tailored to your specific needs, ensuring optimal results for obstructive sleep apnoea (OSA). This machine does not come with an auto adjusting algorithm found on the Prisma20A.

Price Match Guarantee

At CPAP Online, we believe that quality sleep therapy should be both accessible and affordable. That’s why we’ve introduced our Price Match Guarantee Policy – so you’re always getting the best deal possible, without compromising on care and support.

Our Price Match Guarantee applies only to accredited Australian CPAP providers. We do not match offers from overseas companies, and here’s why:

  • Warranty Protection – ResMed Australia and other local suppliers honour warranties purchased through accredited Australian businesses (up to 5 years). Overseas purchases typically only include a shorter warranty, often just 2 years, and may not be valid in Australia.
  • Shipping Costs – Warranty claims with overseas suppliers usually require sending the unit back internationally, which can cost up to $150 each way.
  • Network Compatibility – Overseas CPAP machines often have built-in modems that are not compatible with Australian networks, meaning connectivity features and apps will not work here.
  • Customs & Duties – Importing from overseas can attract additional customs and duty charges (typically around $150), payable each time the unit is shipped, including for warranty claims.

How It Works

  1. Seen a lower price? Let us know before you buy.
  2. Send us the link to the product on their website, or the original quote, via our contact form.
  3. Once verified, we’ll match our competitor’s price — easy as that.

Do I Need a Prescription?

In Australia, you are not legally required to have a prescription to purchase a CPAP machine.

However, it is strongly recommended that you discuss your sleep apnoea treatment with your primary healthcare provider or sleep specialist.

To ensure we can help you achieve the most effective and safe therapy, we encourage customers to upload their prescription and/or recent sleep study results when placing an order. This allows our trained sleep technicians to provide more accurate guidance and assist with appropriate machine setup. However this is not mandatory.

Machine Setup and Therapy Support

If your doctor or specialist has supplied specific pressure settings or clinical recommendations, our sleep technicians can configure your device free of charge.

Simply place your order and leave a note at the bottom of the checkout page under 'Notes About my Order' or send your prescription or sleep study report through our Contact Page.

If you do not have prescribed settings, most modern Auto-Adjusting Positive Airway Pressure (APAP) machines use advanced algorithms to automatically adjust pressure on a breath-by-breath basis, delivering effective therapy without requiring manually set fixed pressures.

Important Notes & Safety Information

  • CPAP and APAP devices are medical devices. Always use them in accordance with advice from a qualified healthcare professional.
  • This information is not a substitute for medical advice. Please consult your doctor if you have concerns about symptoms, treatment suitability, or therapy settings.
  • CPAP therapy may not be suitable for all patients, particularly those with certain respiratory, cardiac, or neurological conditions. Seek medical advice if unsure.
  • By uploading your prescription or sleep study report, you help our technicians ensure your therapy setup aligns with Australian clinical best practice.

Types of CPAP Masks

Full Face Masks
Cover both the nose and mouth, making them ideal for mouth breathers or individuals with nasal congestion. They provide a secure seal and consistent airflow, even at higher pressure settings, ensuring effective therapy. While they offer the most coverage, they can feel bulky and are best suited for back sleepers or those who need maximum support.

Compact Full Face Masks
Are a smaller, lighter alternative to traditional full face masks. They cover the mouth and sit under the nose, reducing bulk and eliminating pressure on the bridge of the nose. This design is perfect for side sleepers or users who want less obtrusion while still benefiting from dual-coverage therapy.

Nasal Cradle Masks
Cradle the base of the nose, delivering effective airflow with minimal facial coverage. This gentle design reduces pressure marks and irritation, making them a great choice for sensitive skin. Lightweight and unobtrusive, they are perfect for side sleepers or users who want a soft, natural fit without anything sitting in or over their nostrils.

Nasal Pillow Masks
Feature small prongs that sit directly in the nostrils, offering precise airflow with minimal facial contact. They are the lightest and most low-profile option, making them ideal for active sleepers or users who feel claustrophobic with larger masks. Their unobstructed design also allows for easy reading or watching TV before bed.

Nasal Masks
Fit snugly over the nose, providing a lightweight and minimal-contact option for nose breathers. They deliver effective airflow for mild to moderate pressure settings and are versatile enough for most sleeping positions. Their unobtrusive design makes them a popular choice for users who prefer a less intrusive mask.
