Review on HiWater Filter Coffee Machines Replacement by Tina Peterson

How do I know if these filters are working? We do not know. If they had sand and a screen in them, they would feel and probably work just as well as the more complex/active ingredients. But as we'll never know until they match our Jura Giga and the water flows really well with no added flavor or coloring. The price is definitely cheaper than filters from the Jura brand (outrageously overpriced). They're still overpriced, but what can you do?
