One of the trends in home water filtration has been the residential reverse osmosis systems. These systems are designed to filter water of everything in it- including the minerals. This is done by using water pressure to send it through a very fine filter. Anything larger than a water molecule is then left behind.
Once the fine-pore filter is used, there are still other items that are to be removed from the water. In many of these systems, all of the particles that are bigger than water molecules are left in the water. This means that items like pesticides are left in the drinking water after it has been filtered.
There are some systems that use a multi-stage filtering system. The reverse osmosis systems residential filter can be accompanied by a carbon filter to remove the larger particles after the other particles have been removed. This takes out more of the harmful substances, but it can be expensive and complicated to install.
This system sounds like a good idea- it takes impurities out of the water and it can get rid of harmful chemicals and toxins like lead and chlorine. These features made reverse osmosis systems residential favorites for a short time. On the surface, it does sound like the most effective system. The residential reverse osmosis systems do offer extremely thorough filtering, just like they claim.
Unfortunately, there is a lot more to the outcome of water that has been filtered this way than the ads let on. When water is subjected to such fine filtering, it loses much of what makes water so healthy. While residential reverse osmosis systems can remove some of the chemicals that can cause health problems, it actually adds other health risks.
The minerals that are filtered out by these residential reverse osmosis systems are the same ones that people need to consume every day. They have been consumed in drinking water for millions of years and are still needed just as much by the human body. A lack of these essential minerals can cause a variety of health problems.
There are also a number of environmental concerns with these filtering systems. Much of the water that the system puts through the filter is not used because of the many particles in it. That means that there is an enormous amount of waste water left behind. The amount of water used is two to three times as much water as is actually produced.
There are a number of other problems that can be caused by reverse osmosis systems. Residential systems are notorious for requiring a great deal of maintenance. They also cost more to operate than other types of filtering systems.
Now that these facts are becoming known, reverse osmosis systems residential use is declining. If the aim is to end up with distilled water for industrial purposes, these systems may be effective. But, to keep the minerals that are needed in drinking water, a different type of filtering should be used. There are filters that both take the toxins out of water and leave in the essential minerals.
