National MS-X1

Launched in Japan on 10 March 2003, it drew in room air and used a membrane to produce air containing about 30% oxygen. A tube fed a small mouthpiece positioned close to the nose.

Marketed for short sessions after work, sport or study, it was explicitly not medical equipment. Panasonic lists production as ended but gives no discontinuation date.

The MS-X1 brought oxygen enrichment into the home as an everyday wellness ritual. Its membrane system, wearable headset and timed sessions packaged a specialised air-separation process into an appliance marketed for use after work, exercise or study. It reflected a period when Japanese manufacturers explored increasingly specialised personal-wellness products. Although National promoted oxygen-enriched air for refreshment and concentration, the MS-X1 was explicitly not medical equipment, and its advertised benefits should not be confused with clinically established oxygen therapy.

- Oxygen and nitrogen passed through the membrane at different rates, creating the enriched output stream. - Output was approximately 2 litres per minute through a 1.5-metre tube, with the mouthpiece positioned about 1–3 centimetres from the nose. - The over-ear band and O2 mouthpiece formed one delivery assembly rather than separate output modes. - The appliance weighed 3.8 kilograms.

- The controls offered 10-, 20- and 30-minute sessions; the manual suggested about ten minutes per day as a guide. - After oxygen mode, the appliance paused briefly and ran approximately one minute of ordinary-air ventilation. - A detachable capsule collected moisture, while the filter, tube and mouthpiece required cleaning; a separate post-use ventilation cycle cleared the system. - By August 2003, the manual listed replacement headset, tube-set and O2-mouthpiece components separately.

- A Reuters photograph records a Tokyo demonstration on 22 January 2003, ahead of the Japanese launch on 10 March. - The manual suggested use after work, sport or long study sessions but explicitly stated that the MS-X1 was not medical equipment. - Reuters metadata reported a planned price of ¥48,000, while Panasonic’s archive displays ¥52,800 including tax; these should not be treated as equivalent launch totals. - Panasonic marks production as ended without giving a manufacturing-end or withdrawal date.
