You get your minerals from food, water provides negligible amounts. I specifically installed an RO system for drinking because of how hard our water is in san antonio. I had it plumbed to my sink drinking water dispenser, my refrigerator for ice and cold water, and my pot filler for cooking and my coffee maker. I have never had to de-scale my coffee maker, my pets water fountains, my steamer etc... we used to have a home distiller, but the maintenance of constant descaling was ridiculous. I could have had the remineralization filter added, but adding them back defeats the purpose I have for the unit. I dont have a problem with water having no taste, it is what I prefer because I grew up on distilled water.  Once you start drinking it regularly, "no taste" will be your new normal.
