• Removes chlorine, taste and odor, and chemicals.
• Carbon block, if pore size is 3 micron absolute or less, can remove cysts.

• Does not remove heavy metals (carbon block can remove undissolved lead)
• Bacteria can multiply in filter (silver is often used, but is considered a toxin by the EPA and as such must be registered with them).
• Limited life because of dual duty - chlorine and chemicals.
• Carbon block filters can clog with sediment long before filter is exhausted.

ADVANTAGES OF REVERSE OSMOSIS

• Removes chlorine, taste and odor, and chemicals (with carbon prefilter or postfilter).
• Removes heavy metals, such as lead.
• Can remove cysts - but not recommended.

• Slow - 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 these minerals leaves a flat tasting water.
• Bacteria can foul membrane.
• Expensive to maintain.

ADVANTAGES OF DISTILLATION

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

• Slow - 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 these minerals leaves a flat tasting water.
• Requires frequent cleaning of tank, frequent replacement of carbon post filter.

UNIVERSAL WATER 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 water.
• Low maintenance; low operating costs (about 1 cent per gallon).
• KDF media inhibits bacteria growth throughout the unit - uses no silver.
• 5 to 10 times longer life than GAC only filter.
• Optional ceramic prefilter can remove bacteria and cysts.
