Other Treatment Technologies

How do other water treatment methods compare with Solid Carbon Block Filters?

 

End of Tap (Faucet Mount)

  • Low filter capacity. Frequent filter changes needed, resulting in ongoing filter replacement costs.
  • Reduces some contaminants of health concern.
 

Carafe/Pitcher (pour-through)

  • Reduces some contaminants of health concern, but not VOCs. Inconvenient to use: water must be poured through the filter and then refrigerated while you wait.
  • Low capacity requires frequent filter changes.
  • Must replace filters about every 40 gallons at $7-$10 each, or $130-$190 for 750 gallons (Multi-Pure’s 750 gallon filter is only $59.95).
Reverse Osmosis

Reverse Osmosis

  • No independent ability to reduce most Volatile Organic Chemicals.
  • Very low output - takes up to 24 hours to process 5 gallons of water.
  • Must have holding tank to store the processed water.
  • Wastes water - for every gallon processed, 3 to 9 gallons are wasted.
  • Removes minerals and trace elements essential to good health.
Charcoal

Charcoal Filters

  • These come in powdered or granulated form which allows water to flow around rather than through the carbon.
  • Referred to as taste and odor filters because of the limited contact time the water has with the carbon.
  • Can promote the growth of bacteria.
Silver - Charcoal Filters

Silver-Charcoal Filters

  • Same as Charcoal Filters above; however, uses silver to inhibit the growth of bacteria while water sits in filter.
  • Silver ingested in certain doses can be poisonous to the human body; therefore, it must be registered with the EPA as containing a poisonous substance.
Media Filters

Limited Media Filters

As the demand for quality drinking water continues to grow, new types of media will be test-marketed, from metal shavings to coconut shells. Some materials can be quite ”exceptional” in reducing a particular contaminant in the water, but there is a wide range of contaminants that should be addressed - not one or two.
Distillation

Distillation

  • Removes dissolved minerals and trace elements essential to good health.
  • No independent ability to remove all chemicals - the chemicals can vaporize and recondense into the distilled water.
  • Daily chore to provide enough water for the entire family.
  • Requires electricity at a cost of about $240 per year.
