Performance caveats in the manual

The manual says flow and purity may be affected above 5,000 ft, above 95°F or above 93% relative humidity. If you live at altitude, read oxygen at altitude and ask your supplier.

Running cost

At 639 W for 24 hours, that’s about 15.3 kWh a day, or roughly 466 kWh in a 30.4-day month. See our electricity cost guide.

Verdict

From the documents, the 1025DS is a lighter 10 LPM concentrator with a built-in oxygen alarm and bottle-filling support. Its purity drops toward the low end at high flow, and the manual flags reduced performance above 5,000 ft, so high-altitude users may prefer the Intensity 10.
