: Summary: G.A.C. & Carbon-Block:

Advantages of Granular-Active-Carbon (GAC) & Carbon-Block:

• Remove chlorine, taste, odor and chemicals.
• Carbon block with a pore size of 3 micron absolute or less, can remove cysts.

Disadvantages of Granular-Active-Carbon (GAC) & Carbon-Block:

• Does not remove heavy metals (carbon block can remove undissolved lead)
• Bacteria can multiply in the filter (silver is often used, but must be registered with EPA as they consider it a pesticide by its function in this application).
• Short life because of dual duty: chlorine and chemicals.
• Carbon block filters can clog with sediment long before filter is exhausted.

: Summary: R.O.:

Advantages of Reverse Osmosis:

• Removes chlorine, taste, odor, and chemicals (with carbon prefilter or postfilter).
• Removes heavy metals, such as lead.
• Can remove cysts, but not recommended (bacteria can eat holes in the membrane).
• High quality multi-stage systems can produce B.E.V.-quality healing water.
• Specialized systems can concentrate alchemical M-state minerals (ORMUS) that feed the spirit body.

Disadvantages of Reverse Osmosis:

• Slow: typically 2 hours to make 1 gallon of treated water.
• Wastes water: 4 - 5 gallons of water go down the drain to treat 1 gallon.
• Removes healthful minerals, such as calcium and magnesium.
• Removal of beneficial minerals leaves a flat tasting water.
• Bacteria can eat holes in the membrane.
• Expensive to maintain.

: Summary: Distillation:

Advantages of Distillation:

• Removes chlorine, taste and odor, and chemicals (with carbon postfilter).
• Removes heavy metals, such as lead.
• Kills bacteria and cysts.

Disadvantages of Distillation:

• Slow: typically 5 hours to make 1 gallon of treated water.
• Wastes energy: uses 25 cents of electricity to treat one gallon.
• Removes healthful minerals such as calcium and magnesium.
• Removal of beneficial minerals leaves a flat tasting, dead water.
• Requires frequent cleaning of tank, frequent replacement of carbon post filter.

: Summary: Favorites of the Wizard:

KDF/GAC Filter:

• Water on demand: no water or energy waste.
• Removes a wide range of contaminants, including heavy metals.
• Leaves healthful minerals intact, leaving tastier mineral-rich water.
• Low maintenance; low operating costs of about 1 cent per gallon.
• KDF media inhibits bacteria growth throughout the unit with no silver.
• 5 to 10 times longer life than a GAC filter alone.
• Optional ceramic prefilter can remove bacteria and cysts.

• Produces water on demand at about1/4 gallon per minute.
• Produces healthful highly alkaline water rich in nutrient minerals.
• This water is enriched with electrons as a powerful antioxidant.
• Water clusters are half the normal size, penetrating 10X better into body tissues, lymph and cells.
• 50% of the total input water volume is optimized for drinking and cooking.
• Acid 'waste' water is useful topically and for cleaning

Sango-Coral:

• Adds beneficial highly absorbable, alkaline ionic macro-minerals like Calcium and Magnesium that neutralize acidity.
• Adds 72 ionic trace minerals.
• Adds rare earth minerals shown to increase longevity up to 2X in laboratory animals.
• Adds electrons to make a potent antioxidant water.
• Changes Chlorine to Chloride and removes toxins by redox reactions.
• Removes toxins by adsorption and ionic exchange.
• Adds M-state minerals that feed the mind and spirit-body.
• Can be added to Microwater or other filtered, purified or distilled water.
• Can be added to drinks, food, including baked goods.
• Can be used conveniently at restaurants and when travelling.
