It is a device that makes a perfectly brewed cup of coffee. But since you only drink hot water, you won’t need one.
I heat the water to make Celestial Seasonings' caffeine-free Lemon Zinger tea. It is the best.
My wife drinks coffee but I can't under doctor's orders after my open heart surgery and my irregular heart rate.
I was just curious what this K thing was once I'd never heard of it before.
I told another poster that it sounded like a German-made farm implement that I could attach to my John Deere.
Thanks for responding. 😂
