iSpring PH100 pH+ 6-Stage Under Sink Reverse Osmosis RO Drinking Water Filtration System 100 GPD Fast Flow 1:1 Pure to Waste Ratio with Alkaline Remineralization, US Made Filters

I got this one. It doesn't waste a much water as some and add minerals back to the water. It's about 320...

AquaTru is one brand. You can get a filter that put the minerals back in, or just add 1/4 tsp Himalayan salt per liter of filtered water.

I just ordered it online and had it delivered. Buy direct from the manufacturer or online from Amazon or Best Buy or similar.

The brand I chose is the "Megahome Countertop Water Distiller Stainless, Glass Collection". I then purchased a bag of the above mentioned Ultra Pure Prewashed Virgin Coconut Shell Activated Carbon to put in the included spout filter. You get a good-sized bag and it lasts forever. The activated carbon really improved the flavor, without it, the water tastes flat.

Note: I purchased another brand of charcoal for use in water purification specifically to steal the polyester mesh bag that was included. I took the material from the bag and cut the size I needed to fit in my spout which will last forever and not break down like the paper filters do. It is rated for drinking water, so it is safe. I put the filter in, leaving the top open and just pour in the right amount of prewashed virgin coconut shell in there, tamp it down with a spoon and I am good to go for a month or two. One 16 oz bag will last probably three years.

The set up works just dandy. Makes really good ice cubes, too.

I do not add minerals. I use Himalayan salt and lots of spices on my food and eat a lot of fresh veggies and fruits, plus a ridiculous amount of supplements. I am hoping I get my minerals that way.

BTW - I just had a well-check blood test. It showed normal levels of calcium, D3, sodium, etc. No deficiencies noted. So I must be covering the bases.
