Reverse Osmosis Purifier or
Carbon Water Filter

Which Is Best For You?

Should you purchase a Reverse Osmosis water purifier or a carbon filter for your drinking and cooking needs? Once you understand the difference between the types and the reasons for usage... the choice will be clear.

Tap water can be a source of bacterial, viral, or chemical contamination since the municipal water treatment process doesn't remove all contaminants and parasites.

Single-celled protozoa, such as cryptosporidium and giardia, are particularly troublesome because they can often slip through local water-purification treatments unharmed. They are resistant to chlorine.

Which is the best type of water treatment device and why should you even install one?

  • Which produces the best tasting water?
  • Which removes the most contaminants?
  • Which is the safest choice for you and your family?

Giardia protozoan - water contaminant

Some microscopic organisms, such as giardia, are protected by a tough outer coat. The chlorine added to municipal water supplies to kill germs has little effect on them.

Because of their small size, very fine filters are needed to trap them, and complete elimination of these parasites from tap water isn't possible.

Drinking water regulations are designed to reduce - but not necessarily eliminate - parasite contamination. Even water systems that meet government standards may not be free of parasites. Water treatment plants are constantly monitored to detect levels above acceptable limits, but even then there's the potential for giardia or other infection.

The cost for a municipality to completely purify all tap water would be prohibitively high and impractical. We don't need purified water to wash our car, fill a swimming pool or hot tub, or water the lawn and garden. It makes more sense for individuals to purchase water filtration devices appropriate for their personal needs.

An R/O Purifier Is The Best Choice for Drinking & Cooking

  • A Reverse Osmosis water purifier is the safest. It removes the most contaminants, including viruses and fluoride.
  • R/O water is the best tasting, making it easy to drink your adequate daily amount.
  • Read the comparative chart below to see the differences between a reverse-osmosis purifier and a carbon filter. You'll be convinced of the superior taste and function of the R/O purification system.

When is a Carbon Water Filter More Appropriate?

  • Use a shower filter or bath-water filter to eliminate toxic chlorine vapors and absorption of chlorine through the skin.
  • An inline filter is useful for filling the drinking water troughs or water dishes for your animals and pets.
  • Use a carbon filter in the bathroom for brushing your teeth or washing your face.
  • An inline water filter will eliminate sediment when filling a fresh-water RV tank.

Safety Considerations

  • Be sure you have water containers that are safe for storage and transport. Avoid containers that can leach carcinogenic and hormone-disruptive chemicals into your drinking water.
  • You will drink more water if it has a great taste and you know it's pure.
  • R/O water is preferable to distilled water - which can leach minerals and electrolytes from your body.
  • Scientists and health professionals are now warning us of the dangers of fluoride - which is primarily removed by reverse osmosis technology.
  • Children are especially vulnerable to the toxicity of chlorine and fluoride in drinking and bath water, and in the preparation of baby formula.
