I created a device that controls the percentage of co2 mixed in regular air. It goes up to 7%.
I need to create a legal document for people who buy it that they are responsible for the outcome of using it and that I make no claims that it will anything for them. They use it at their own risk.
I have done extensive research and breathing in up to 7% co2 is very safe and there are many health benefits.
I won't be selling it to a lot of people. Just people who understand the value it has without me needing to explain it.
