I use this filter for my coffee water. My machine thanks me for that :-)
I also use the filter water for some applications (like milk tube cleaning) it leaves no residues.
What I liked most is the ability to get filtered water, from the tap at home. This means reduced energy to transport bottled filtered water by transporting way less mass of the filter.

I dont use it for drinking water my tap water is good. However I liked this brand for the capacity to reduce TDS better than other well known filters. So if TDS concerns you, this is good choice.
