Frequently asked questions

How long does the battery last?

Both 8-cell and 16-cell hot-swappable batteries are available. The 16-cell pack runs 2.5-8 hours and the 8-cell 1.2-4 hours. Runtime depends directly on the flow setting: higher settings drain faster. Because batteries are hot-swappable, carrying a spare gives continuous operation.

Does purity stay stable at altitude?

Yes. The unit delivers 90% or higher purity and holds stable measured values in Lhasa at 3,650 m. The 2.8-inch colour screen shows purity and flow in real time so you can confirm the current state at any point.

How heavy is it, and is it practical to carry?

The host weighs 1.45 kg and measures 170 by 80 by 198 mm, so it can be carried on a shoulder strap or packed in a daypack - suitable for hiking, driving and everyday use.
