This product is called Ruach, which means “breath”. This product is all based around increasing oxygen, better breathing, better lung capacity, etc. It has a Biblical context, meaning “breath of life”, which I want to base the design around but also mix in the functional element of the product which is what I described above with increasing oxygen capacity, etc.  I’m thinking of a modern style with Biblical themes surrounding it. Ruach can be used to describe God as a wind, breath, or Holy Spirit. So it leaves room for your creativity. 
Some verses below that reference Ruach. 
“Then the LORD God formed a man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being”
“When the Ruach/breath comes upon you, you will receive all power.”

Below are some labels that I like that represent the modern look. I like the background of the Gho cans and how they have the words blended in the background that fit into their color scheme. I think having words in the background like on those cans with images that represent Ruach could be a cool look. 

Also below you’ll find an image of the breath of life and coming from dust. It’s a reference image to create a similar photo design to go with the name and meaning of Ruach. Feel free to create an image that represents something similar and mix it with the background look of the Gho cans. Be creative. 

God Bless!
