With Philips’ departure from the sleep diagnostics space earlier this year, sleep disorders centers may find themselves in a lurch concerning replacement parts for the Alice line of diagnostics equipment, including Alice 6, Alice NightOne, and Alice PDx.
Shipments of these systems have already halted, and their end-of-service dates are January 25, 2029 (for Alice 6 and Alice NightOne) and October 1, 2028 (Alice PDx). According to Philips, it will continue to support discontinued Alice products with repair kits, spare parts, and consumables depending upon parts availability up until the end-of-service date. Philips will provide refunds (as articulated in the warranty terms and conditions) but won’t provide replacements for discontinued products that fail within their warranty periods.
Many other vendors have stepped up to fill potential voids and have Alice-compatible consumables available.

| Description: | These durable and moisture-resistant sensors produce clean and reliable snoring signals. Low profile with a patient friendly shape and use soft elastic polymeric to maximize patient comfort. The sensor attaches to the neck. | Sleepmate Thermal Airflow Sensors utilize a single channel to record oral and nasal airflow, are compact and comfortable, and made from materials that make them easy to adjust to the patient. Sensors are available in reusable and disposable versions for adults, pediatrics, and infants. | Compumedics offers an extensive consumable offering for both sleep and EEG monitoring. All of its EEG, ECG, EOG, consumables are standard 1.5 mm connectors and can work with Alice. | MyCustomPSG Kit is a customized solution containing your chosen combination of disposable sensors and electrodes needed for PSG testing – ALICE 6 Compatible. Designed to bring convenience and efficiency to sleep labs, MyCustomPSG Kits can help simplify patient setup, eliminate cross contamination, and streamline sensor ordering and inventory management. | A comprehensive collection of essential sensors for recording PSG respiratory parameters. RespiPack Contents: PerfectFit 2 thoracic and abdominal effort belt modules, 45” and 60” effort belt straps, TriplePlay airflow sensor, AccuSnore snore sensor, and all required interface cables. | The DC Pressure Sensor / Alice 6 Compatible is designed specifically for use with Alice 6 systems and monitors pressure and snore. The internal piezo crystal senses minute pressure changes and filters them into two bands; one for slow waves to the flow channel and one for fast waves into the snore channel. The sensor plugs directly into the headbox (no external power source is required) and will work with any brand of pressure monitoring cannula. | Piezo snore sensor | Adult nasal and oral airflow sensor with cannula attachment | The SleepSense Adult Inductive System Kit includes 2 fully adjustable RIP/inductive belts and 2 inductive interface cables that are compatible with the Alice 6 system. | SleepSense disposable ThermoCan Cannulas are uniquely designed with a built-in thermal airflow sensor, making it easier and more comfortable to monitor nasal pressure & oral/nasal thermal airflow simultaneously. Use with SleepSense ThermoCan Interface Cables to transmit the thermal airflow signal to an Alice 6 system. Available with or without dual lumens for capnography monitoring. | |
