Drinking Water FAQs
What about those bottles of water that so many people have become attached to? First, they’re expensive — sometimes costing more than $1.00 per liter, which translates into 800 to 4800 times the cost of tap water. Second, they’re cumbersome to tote, and you have to go to the store to purchase them. Third, all of those plastic containers must be recycled, or they’ll crowd landfills. And finally, depending on the source of the bottled water, it may be nothing more than filtered municipal water. Also, Federal standards for bottled water are no stricter than standards for tap water. In-home drinking water systems deliver the same benefits and more, without the inconvenience — and are actually less expensive than bottled water, with a Kinetico VX Plus Deluxe delivering better than bottled water for as little as 7 cents a liter.
The US has been chlorinating its water supplies for over one hundred years, virtually wiping out water-borne diseases such as cholera and typhoid fever. However, when chlorine breaks down organic material, it creates byproducts (such as THMs / trihalomethanes) that can damage the heart, kidneys, nervous system and lungs and increase the incidence of certain cancers. The EPA has responded with limits on chlorine byproducts permissible in drinking water. Eliminating the byproducts of chlorine should be a primary objective in any personal water treatment plan.
One can go weeks without food but only days without water. In a typical day you lose 2 to 3 liters of water. If you don’t replace it, your body pulls water away from your skin, nails and hair to the critical systems that need it. Drinks with caffeine are diuretics and promote water loss; fruits, vegetables and juices help but add calories. Water is calorie free, which is why it’s recommended we drink 8 ten-ounce glasses of water each day.
Studies have found that minerals in your drinking water make essentially no contribution to your health and may even be present in forms your body can’t absorb. You are much better off maintaining a balanced diet. However, for those who want to add healthy minerals to their drinking water, we offer the Mineral Plus FlexFiltration cartridge for the Kinetico K5 Drinking Water Station.
While bottled water is generally of good quality, Federal standards for bottled water are no stricter than standards for tap water. It is a lot less expensive to own a Kinetico K5 Drinking Water Station when you consider the time and costs associated with bottled water — and your system lets you use the water for many purposes including cooking, without rationing, and without storing bulky plastic bottles.
There sure are! Water Doctor of Washington is proud to partner with Salal Credit Union. Give us a call for more information!
