Why the filter for the well water? Well water can change over time but that might be a good thing especially considering you mentioned that it tastes good before filtering it.
I wonder how do you do it? In another thread, you stated you get along without a cellphone and now you also have well water? I thought maybe you live in a rural area but you're an engineer so maybe not. Anyway, I'm just jealous that's all. but I'll get to that point one day as well. 
Well, primaD I was feeling pretty low this winter. I thought it might be vitamin d lacking, so I ate more fish. That didn't do much. I was just not feeling right in a minor sort of way - moody, depressed, etc. It dawned on me that it might be something in the water, like selenium, which does occur in large amounts in some Texas regions. Our water is also very hard here. The last time we tested the water, the only high amount we noticed was copper. Then I also thought about all the natural gas drilling in this area as of late. (This activity has now gone down, as have the prices for natural gas & oil.) Gas drilling can contaminate and/or deplete wells nearby. There is/was drilling within about 1/2 mile or a bit more, but this site is at a lower elevation than my property. So, while I could do extensive testing for most known contaminants - at a cost of about $200+ per test - it made more sense to filter our drinking water by reverse osmosis. RO filters most every problem constituent of water. We have a sediment filter for the whole house as well, and we have to soften the water for showers and stuff or we get stalagtites growing on the faucets (no joke). Fortunately, my husband placed a diverter valve at the softener when he plumbed it in, so we can switch between hard and soft water any time we choose.
Anyway, about the same time a couple months back, a friend of mine gave me all these different seaweeds as she went on a GAPS diet. Well, after a week on the seaweed, I did feel better. Perhaps I needed more iodine. Or perhaps it was the water change. I do not know, but things are good now, and I am happy. I am the extroverted motivator that I always was once again.
My background is mechanical engineering, and I own a very small software business and work out of my home. I am quite eager to develop "green" hardware or microcontroller technologies for consumers in the near future, as I have some good ideas on that front and want to be a constructive force in a sick world. My husband is an electrical engineer. Most of my time now is spent homeschooling my sons. I do live in a semi rural setting on almost 2 acres, complete with fruit trees and laying hens. I can raise any livestock here except pigs. I'd like to try out raising sheep, but it will be a time commitment. Maybe my older son can try it. We may also buy more land in the not so distant future for hunting purposes mainly.
We still do not own a cell phone. We may break down and buy one eventually, but then again, we have survived this long ... DH was once at a IEEE meeting in the 1990s where the founder (iirc) of Motorola said he did not use mobile phones any longer as he developed a head tumor from one. They transmit microwave radiation over vast distances, which requires much power any time the device is on. So if you wouldn't cook your food in a microwave oven, why would you put a smaller, less powerful microwave transmitter next to the soft tissues in your head? The answer for most people is that they don't think about the em radiation, just like they wouldn't think much about walking in front of an active radar on an aircraft sitting on the flight line, even though their gonads will get fried to some extent by doing so. People can't feel it, so they ignore the fact that wireless devices, like laptops, can adversely affect their health. Distance is key too; the closer you have the device to your body, the worse the effects. So if you keep your awareness and distance, that is good. I think children should be banned from using most wireless devices altogether, as they do not understand the risks (nor the underlying science).
So did I hear that you are Korean? I love Korean people, food and culture. My son and I, both Taekwondo Jidokwan black belts, may try our hand at learning the Korean language before we test for 2nd Dan.
I am just rambling on and on here!
