Gary, once someone says a new product is great just sit back and wait and smile.
Time will tell, all I do know is copper has a proven track record over 3,000 years and promotes health in drinking water and is used for medical gas applications and can be used for waste, venting, some types of fuel,water,heating
and many other HVAC /plumbing and steamfitting applications.
One of the few natural materials that is great for most applications in residential and is very easy to recycle if someone cares about the environment.
Gary that was an interesting posting on "filters"
