1. Do I really need to be concerned with the safety of the water that comes from my tap?

Yes! According to the U.S. Environmental Protection Agency, “The American Public can no longer take the purity of our drinking water for granted.” Over 700 organic and inorganic chemicals have been identified in drinking water and some of them are linked to cancer, birth defects, neurological disorders and a host of other afflictions.

2. But my water tastes O.K. and I’ve been drinking it for years and haven’t had any ill effects.

The average person will consume approximately 15,000 gallons of water in a life time. In many water supplies, there are contaminates that even in small quantities, can cause physical disorders as stated above. Most cities have up to 72 hours before they have to notify you that there is a problem with your water supply. Milwaukee and other cities have recently found fecal bacteria in their water supply resulting in some deaths and thousands of people ill. In Phoenix alone, between 1991 and 1992, there were reported to be 17,364 violations of E.P.A. Water Quality Standards, according to the “Natural Resources Defense Council” in Washington. It is not an issue of whether your water is harmful physically or not, the issue is for such a small price, why even allow it to be a concern. Besides, for such a small price, you can have safe water that tastes great too!

3. How is a Costless Reverse Osmosis system different from just a filter?

The quality of the water is much better, your ice cubes will be clear and fresh, and the water will taste great. This is accomplished by using a combination of the three most effective water treatment technologies known. An expert from the office of Water Research and Technology said in the U.S. Dept.of the Interior Publication, 24-000-00855-0: “For general treatment (of water) to reduce both organic and inorganic loading to tolerable levels at lower energy costs, Reverse Osmosis(RO) offers significant advantages. It can accomplish the removal of many classes of contaminates to the desired degree of purity simultaneously. The significance of Reverse Osmosis (RO) is that it provides an additional processing tool with a broader capability, combined with lower energy costs, that has been available in the past.”

4. Will Costless Reverse Osmosis water taste as good as the expensive water I buy?

Yes! Sometimes better, depending how well the bottled water company is maintaining their purification equipment. Reverse Osmosis is the same process used by most major bottled water companies. Even some companies that use “spring water” still use Reverse Osmosis to insure purity.

5. I have heard that Reverse Osmosis systems waste a lot of water.

Absolutely not! On the average, these systems will use less than 2% of your home’s total water consumption. All Costless’s Reverse Osmosis Systems use water conservation valves.

6. How expensive are the filters for my drinking water system?

Depending on what system you purchase, over a year it will be approximately $4/per month for all the great tasting and good quality water you can drink.

7. How often do I need to change the filters on my Costless Reverse Osmosis system?

Once a year. Except on the Classic I-100 and Classic II-400 models — these prefilters are changed every six months and the postfilters are changed once a year. The Reverse Osmosis membrane is changed between two to five years, depending on your incoming water quality. Costless Water Systems will notify you when it is time to change your filters and which ones need changing so you don’t have to worry about keeping track.

8. Do I need to be concerned about sodium in my softened water?

Absolutely not! The amount of sodium that is produced by a water softener is miniscule in comparison to your daily allowance for sodium intake. For a further in depth look about sodium and water softeners or if you are on a sodium-restricted diet or therapy See chart Below.
