in Using your Oxygen Concentrator

Can I use my portable oxygen concentrator in the shower?

You can continue to have oxygen delivered using your cannula and tubing while taking a shower. However be sure to place your oxygen concentrator outside of the bathroom, away from any moisture and remember to turn on your bathroom fan. You may need to use longer tubing to do this, we recommend you keep your tube length to under 5m as any longer can interfere with breath detection.

Oxygen concentrators are not waterproof.

Oxygen concentrators are sensitive electrical devices so be extra careful when using them around sources of moisture, including rain and steam.
