Brita Glenmorangie? Just buy distilled water. deep rock You can have a whole house water treatment system installed for a few thousand $$ or get a Brita or Pur filter for your kitchen sink. There are also Brita and Pur pitchers to supplement the sink filter for storing in the fridge or on the countertop.

20 years ago, I bought an under counter filter system from Amway that worked great for my family of 5.

Now that there's just me, I have a Pur kitchen faucet filter, and a Pur pitcher for extra. I use the 3 stage filters and I have to change filters once a month. I use the filtered water for cooking, rinsing veggies, etc., as well as drinking and teeth brushing.

I also have a shower filter from Sprite so I'm not showering in, and inhaling chlorine gas.

Hope this helps! Sears sells an electric counter top model. It distills the water by steaming and does an excellent job. It makes a gallon at a time and comes with an extra pitcher so you can make some during the night and have it in the morning. The water tastes fresh and pure not at all flat. Because it is distilled rather than just filtered all of the harmful additives and pollutants are removed. I have had mine for about 5 years now and it is as good as new. I think it was about $125 and well worth it. There is no best water distiller. I can offer you an opinion but in the end its up to you to decide which is the best. Sorry your asking a question that can't be answered.
