What is the lifespan of the Neu G7 water activator?

There is no electricity required to operate the Neu G7 water activator.

There are also no user changeable parts whose performance may degrade over time within the device. The entire device is made from SUS 304 stainless steel.

The durability stated in the brochure is > 10 years. The rationale is that the G7 manufacturer has only been in existence in Japan for 16 years (with respect to now, 2017). The product durability is stated as such so that consumers are not misled.

If not misused, the Neu G7 water activator can actually serve you for a very long time.
