Can I use Helsi™ One Sauna Dome outdoors?

No. Helsi™ One Sauna Dome is designed for indoor use only. Place it on a flat, dry floor near a socket.

What wavelengths does it use?

Helsi™ One Sauna Dome has 132 LEDs: 66 red at 630–660 nm and 66 near-infrared at 810, 830 and 850 nm. The heat comes from graphene far-infrared heaters in the domes and the mat.

How much space do I need?

Extended on its mat, Helsi™ One Sauna Dome needs a floor area of 200 × 80 × 3 cm and a nearby 230 V socket. Folded away it stands upright at 100 × 76.5 × 48 cm, about the size of a side table.

What does the warranty cover?

Helsi™ One Sauna Dome comes with a 5-year limited warranty in Germany and 14-day returns. The warranty page lists what is covered and how to make a claim.

Shipping is free in Germany and Helsi™ One Sauna Dome ships in 3-5 working days. It arrives with the domes, the mat and the rechargeable Bluetooth controller.

Can I use red light without the heat?

Yes. The controller has three modes: infrared, red light or both, so you can run a red light session without the far-infrared heaters.
