Comparison of the Prisma A20 and Prisma Smart Plus CPAP Machines

When it comes to Continuous Positive Airway Pressure (CPAP) machines for managing sleep apnea, both the Prisma A20 and the newer Prisma Smart Plus from Loewenstein have established themselves as top-tier solutions. However, with technological advancements in the Prisma Smart Plus, it seems to be a better overall option for most users. This comparison outlines the differences and improvements, making it easier to decide which device suits your needs.


1. Design and Interface

  • Prisma A20: The A20 is known for its touchscreen interface, which enhances user experience by making settings easy to adjust. It is designed to be simple and functional.
  • Prisma Smart Plus: While the Prisma Smart Plus lacks a touchscreen, it makes up for this with its dedicated smartphone application. The app allows you to monitor and adjust settings remotely, providing convenience and modern functionality that the Prisma A20 doesn’t offer. This is a key factor where the Prisma Smart Plus excels over the A20, making it more suitable for users who prefer tech-friendly solutions.

2. Therapy Modes

  • Prisma A20: Like many CPAP machines, the Prisma A20 offers both CPAP and APAP (Automatic Positive Airway Pressure) modes, making it versatile for various patient needs.
  • Prisma Smart Plus: The Prisma Smart Plus offers the same CPAP and APAP modes, but with enhanced auto-adjusting algorithms. This results in smoother pressure transitions and a more personalized treatment experience, especially for patients whose pressure needs fluctuate during the night. This makes the Smart Plus superior in terms of comfort and response to patient needs.

3. Application and Remote Monitoring

  • Prisma A20: The A20 lacks app connectivity, requiring manual data transfers via SD card or checking information directly on the machine. For patients who don’t need constant tracking or remote access, this may be adequate.
  • Prisma Smart Plus: One of the biggest advantages of the Prisma Smart Plus is its app integration. Through the Prisma Journal App, users can remotely track their therapy progress, adjust settings, and share data with their healthcare providers in real-time. This level of connectivity provides a significant advantage over the A20, making the Prisma Smart Plus a far more modern and accessible device for ongoing therapy management.

4. Comfort Features

  • Prisma A20: The A20 offers standard comfort features like pressure relief on exhalation and customizable ramp settings, helping users ease into therapy.
  • Prisma Smart Plus: Building on the A20’s comfort features, the Prisma Smart Plus has improved pressure adjustment algorithms, particularly for exhalation, providing an even more natural breathing experience during use. This refinement in comfort places the Prisma Smart Plus a step ahead.

5. Noise Levels

  • Prisma A20: Known for its quiet operation, the Prisma A20 is a popular choice for users who value a peaceful sleep environment.
  • Prisma Smart Plus: Like the A20, the Prisma Smart Plus is designed with low noise levels, ensuring quiet operation. There is little difference in noise between the two models, so both are excellent in this regard.

6. Data Management

  • Prisma A20: The A20’s data management relies on manual SD card transfers, which some users may find inconvenient.
  • Prisma Smart Plus: The Prisma Smart Plus offers automatic data synchronization through its app, enabling easier sharing of therapy information with healthcare providers. This makes the Prisma Smart Plus far more efficient and user-friendly when it comes to data tracking and management.

7. Performance and Specifications

  • Prisma A20: The Prisma A20 is a reliable machine, providing consistent CPAP and APAP therapy with solid performance.
  • Prisma Smart Plus: While matching the A20’s performance in therapy delivery, the Prisma Smart Plus offers upgraded algorithms that ensure better pressure regulation and overall comfort. Although it lacks the touchscreen, the ability to control settings via the app and its modern smart features make the Prisma Smart Plus a better overall package for most users.

Conclusion: Prisma Smart Plus – The Better Overall Choice

While both the Prisma A20 and the Prisma Smart Plus are excellent CPAP devices for treating sleep apnea, the Prisma Smart Plus stands out as the better overall choice due to its modern features and enhanced user experience.

  • The Prisma A20 is a solid option for those who prefer a simple, touchscreen interface and are not particularly interested in app connectivity or remote monitoring.
  • The Prisma Smart Plus, on the other hand, offers a more advanced, feature-rich experience with remote monitoring, data synchronization, and a dedicated app. These features make the Prisma Smart Plus a more future-proof solution and more convenient for users who want a modern approach to managing their CPAP therapy.

In conclusion, if you’re looking for a machine that combines comfort, advanced technology, and ease of use, the Prisma Smart Plus is the clear winner, offering better overall performance and convenience in comparison to the Prisma A20.
