Cool!  Would you be willing to share photos or details of your setup?  Or point me to a similar one?<p>I live in Taiwan and currently get drinking water from fill-up stations outside due to heavy minerals in the groundwater here.  It&#x27;s not too inconvenient to do it once a week or so, and the water stations are ubiquitous, but I miss having drinking water from the tap.<p>I&#x27;ve visited water filter shops 2-3 times with the intent of buying a filtration system but am put off by the cost of replacement filters which I know I will have to buy frequently.  I&#x27;m being cheap but the engineer in me keeps saying there&#x27;s a better way.<p>Also, I was not able to figure out how I can test the water quality without sending it to a lab in the US.  Do you test your own water?
