Thank you, @raney. I just read about the zero filter. I saw that they even have a very large one. It seems it uses two types of filters which each last for a different amount of time, and the filtration is 0.02, which is significantly greater than the 0.2.
I had read about using an Instapot to boil the water. That is a good idea because you just set it. As it is, I use a large pot to boil and then other containers in the fridge to store.
