What company makes the most effective pure water systems? This is a good question. If you pay attention to the promotional initiatives, what you know already that each company supplies a pure water system, but there really isn't much "truth" in advertising.
First, there's a question about the true meaning of purity. Should you used the phrase "free of anything different", you may end up getting pure water systems that de-mineralize. Reverse osmosis, for instance. But, minerals are good for our overall health.
If you use the meaning "free of contaminants", you would have a pure water system that removes hazardous chemicals, lead and chlorine-resistant cysts. This is the type of pure water system which i want. Briefly, here's why those things should be removed and just how it is possible, without de-mineralizing.
Chemicals
Based on the Ralph Nader Research Group, you will find 2400 different chemicals present in publicly treated supplies and also the vast majority of them are human carcinogens. Regulating agencies such as the US Epa has built "safe" levels for many of these, but not all.
The safe levels were determined by assuming that there was just one carcinogen inside your glass at any given moment. They also assumed that each individual weighs a minimum of 175 pounds. Scientists have warned that these two assumptions are dangerous. They say that the presence of several chemicals exponentially increases their toxicity.
So, now, regulating agencies have "goal" levels, which are often zero, but facilities rarely, if ever, achieve those goals. Review your local "Consumer Confidence Report" and look for things like TTHMs, if you need proof.
Pure water systems which include a carbon and multi-media block will remove almost all traces of those chemicals. You can read product performance data, to be certain. The very best companies supply the data on their websites.
Lead
Lead is really a hazardous heavy metal and rock that is also a naturally occurring substance. It is contained in surface and groundwater. Aging pipelines have lead solder in the joints and as the water goes by those joints, it absorbs some traces of this lead. Older homes have older pipes, which are more likely to have lead linings. Chlorine eats away at the lead and even more enters your house.
A pure water system which includes an ion exchange step will remove more than 99% of traces from the heavy metal, in addition to traces of copper, which aren't particularly hazardous, but do modify the taste.
Chlorine-resistant Cysts
Pure water systems which include submicron filtration can remove chlorine-resistant cysts. These contaminants cause illnesses that can be fatal to infants, young children, seniors and those with weakened immune-systems.
So, all together a pure water system for the home should include a multi-media block, having a submicron sized porous structure as well as an ion exchange step. These easy steps enhance the taste and healthfulness, without having affected any naturally sourced mineral content.
Advertising for pure water systems could be confusing, however you realize the facts. Hopefully, that clears some misconception.
