Q Do I need a power supply?

A ReVIERA³ uses water pressure to dissolve carbon dioxide, so there is no need for a power source.

Q Doesn't carbon dioxide (CO2) have any adverse effects on the body when used for long periods of time?

A Carbonated spring water is weakly acidic, so it may cause a tingling sensation in people with scratches or sensitive skin. If you feel any discomfort, please consult your doctor before use.

Q Is it safe to use it every day?

A It is said that daily use of carbonated water will have a positive effect on the body from the inside out by promoting blood circulation and improving turnover.

Q Can I use it only in the shower?

A You can enjoy a carbonated bath by placing the shower in the bathtub and filling it with carbonated water. To fill the bathtub with carbonated water, place a basin on the bottom of the bathtub, place the shower head in the basin, and gently let the water flow out.

Q It says it can be used in a variety of ways, but which is the most effective way to use it?

A We hope that you will be able to use this product according to your lifestyle. Since the highly concentrated carbonated water comes directly from the shower, it can be used for a variety of purposes, including washing hair and face, storing it in a container for a footbath, and storing it in a bathtub for a half-body or full-body bath.
