Lowenstein Prisma 20A Auto CPAP Machine — Humidifier, Heated Tube & 4G Modem

The Löwenstein Prisma 20A is the flagship auto-CPAP machine from Löwenstein's premium prismaLINE — a hospital-grade device engineered in Germany for people who want precise, reliable, and genuinely comfortable sleep apnea therapy. This complete kit includes the PrismaAQUA humidifier, PrismaHYBERNITE heated breathing tube, and a 4G modem for real-time remote monitoring via Prisma CLOUD, so everything you need is included from day one.

Key Features

• Forced Oscillation Technique (FOT): The Prisma 20A uses FOT technology to accurately distinguish between obstructive and central apnea events — and precisely identify hypopnea, snoring, RERA, and flow limitations — so every pressure adjustment responds to what's actually happening in your airway, breath by breath.
• Swiss-engineered blower motor: A hand-balanced Micronel blower delivers whisper-quiet operation with substantial performance reserves well above typical therapy pressures. The result is a machine that runs at a near-idle for most users — quieter therapy and a longer working life.
• CPAP + APAP flexibility: Switch between fixed-pressure CPAP and auto-adjusting APAP modes to match your prescription. Two APAP algorithm settings — Standard (lowest possible pressure) and Dynamic (maximum responsiveness to flow limitations) — let your clinician fine-tune therapy to your specific needs.
• softPAP level 3 comfort: Pressure eases at the beginning of each exhale and rises again at the start of each inhale, making breathing feel natural and reducing the effort of exhaling against pressure. Level 3 includes inspiration support — the highest softPAP setting available on any Löwenstein device.
• PrismaAQUA humidifier: Clicks into place directly on the device for a clean, compact setup. The 400 ml chamber uses a heated rod (not a plate), meaning no cracking or leaking over time. It's dishwasher-safe, requires no distilled water, and features Smart Aqua Control (SAC) for automatic warm-up boost and humidity compensation during mask leak.
• PrismaHYBERNITE heated breathing tube: Powers directly from an integrated port on the device — no separate power supply needed. Tube heating prevents condensation and rainout throughout the night for quieter, more comfortable breathing.
• 4G modem + Prisma CLOUD: Includes five years of data transmission. Once attached, your clinician can remotely monitor therapy progress and make adjustments without you needing to visit a clinic. The modem detaches easily when you travel.
• Prisma RECOVER deep sleep indicator: Analyses variability in your respiratory minute volume to provide an estimated deep sleep indicator — giving both you and your clinician a clearer picture of overnight therapy quality beyond just AHI.
• Comfort and compliance features: softSTART gradually builds pressure at the start of each session; autoSTART-STOP senses breathing to begin and end therapy automatically; mask recognition and mask test confirm a secure seal before pressure increases.
• Comprehensive therapy data: 14 days of high-resolution therapy data and up to 365 days of detailed statistics, accessible via prismaTS software through the onboard SD card and USB port.

Who Is This For?

The Prisma 20A is ideal for newly diagnosed patients who want to start with the most capable auto-CPAP available, and for experienced users who are upgrading from an older machine or switching brands. If your sleep specialist has noted complex or variable pressure requirements, or if remote monitoring by a clinician is part of your therapy plan, the integrated 4G modem makes this kit particularly well-suited. Anyone who has struggled with tube condensation, rainout, or humidity-related dryness will also benefit from the combination of the heated breathing tube and PrismaAQUA humidifier working together.
