Clean water is a good thing, and reverse osmosis filtration is a good way to get good clean water. There are other ways to get clean, great tasting water. But reverse osmosis is a great way to get great water at a reasonable price. The price of a reverse osmosis system need not be prohibitive, and the pleasure and health benefits are considerable. The wide variety in size and style of RO treatment systems available put great treated water within the reach of most people.
One of the benefits people look for in filtered water is great taste, which really means the removal of bad taste common in municipal drinking water supplies. Filtered water makes better coffee, and that is mighty important to many of us. And if your city water has an unpleasant taste and smell, it isn't going to improve the taste of your cooking either.
Reverse osmosis home water treatments are available in a variety of installation packages, suitable for most budgets. There are counter-top models that will produce water for drinking and cooking. There are under-sink models that will produce considerable amounts of water, often dispensed through its own little faucet. Then there are the larger whole-house supply units, often installed in a basement. If you care to go to a whole-house treatment system, you get the benefit of RO filtered water in your sink, showers and bathtubs too. That will mean you are soaking and washing in clean, contaminate-free water rather than smelly city water. That's worth the price of a system, right there.
Reverse osmosis filtration systems are really a combination of several filtration treatments, including RO in the middle somewhere. A typical system might work something like this: A sediment pre-filter takes out the heavy stuff, all kinds of particulate matter from outright evil to merely annoying and filter-clogging. A second carbon filter removes chemicals and contaminates that make water nasty and might also damage the RO filter membrane, reducing its effectiveness. Then comes the reverse osmosis filter, which works by forcing the pre-treated water through a semi-permeable membrane, allowing nothing larger than a water molecule to pass through. Then, there may be final filtration through activated carbon, to assure sparkling clean water as a final product.
That's really water treatment by at least three filtration methods, but we still call it reverse osmosis treatment, and it's still a good thing. You can get small systems that you can hook up yourself. But you may want to consider having a qualified professional in to do the job. A pro can advise you on what's needed in your area, and then make sure the system is installed correctly to function properly.
Then, no matter what type RO system you choose, you can fill your glass with some of those crystal-clear ice cubes, pour the beverage of your choice, or maybe just some great water, and toast yourself for providing great water for yourself, family, and friends.
