Reverse osmosis water may offer the best combination of cost and quality. However there are several factors to consider if you think reverse osmosis may work for you.
How Does It Work?
MEMBRANE
It's a simple concept based on some serious technology. Water pressure forces water through a very fine mesh filter membrane. Many pollutants can't make it through the filter and are thus excluded from the finished product.
Does It Take Out Minerals?
It gets out virtually all minerals plus many other problems too. Usually included in the finished system are sediment filters plus carbon filters too. That takes care of most chemicals, even drugs, toxic metals, and most microorganisms.
What About Taste?
The basic reverse osmosis membrane won't take out what usually affects taste or odors. For those problems, an included carbon filter solves those issues. Carbon improves taste and eliminates objectionable odors too. Carbon filtration usually comes in easily changed cartridge form.
Is The Finished Product Expensive?
Membranes last a really long time. Especially with sediment pre-filters to keep out the particles like iron and manganese, the main membrane will rarely need changing. Other filters including carbon cartridges will require changing more frequently. Other costs to consider with reverse osmosis are water waste costs. For every gallon of filtered material, 3 or more gallons of water are rejected and wasted. Not only is the waste not used, but it must be dealt with as waste too.
Can Anybody Use One?
Water pressure forces water through the filter. That means you must have about 35-40 psi pressure for a filter to work. That normally is no problem for a municipal system. For rural systems it may mean a booster pump must be added.
Reverse osmosis water excludes most kinds of pollution. It does involve some costs that you may not notice at first glance. Plus it works better with municipal water and waste systems instead of rural systems.
