All I drink is Ionized Water . I really feel a difference drinking it, and won't go back to normal water, and I "treat" water for a living. Look up the "Regency II" water filter. I think they're around $650 now. You can set the ph to 11 which is all I drink and it treats 1000 gallons, which is about what I drink in a year.

I tried magnetic water at a fair one time and it seemed to give me energy, but I haven't invested in one of those yet.

I drink Ozonated water alot. Not really sure what kind is better for you, but I enjoy the Ozonated water.

1. Bottled water: pricey
2. Distilled water: need to buy a distiller
3. RO water: need a ro system to purify water
4. soft water
