Is a Reverse Osmosis Water Dispenser More Effective Than a Multi Stage Water Filtration System?

A reverse osmosis water dispenser may not be the right choice for your family. There are many things to consider before you buy reverse osmosis water filtering systems. We'll look at some of them here in this article.

First, you should decide if you actually need a reverse osmosis water dispenser. Everyone needs to purify their tap-water before drinking, but reverse osmosis water filtering systems are more expensive than competing technologies that are just as effective.

Whether or not you actually need the reverse osmosis water dispenser depends on what is in your source. If you are serviced by a treatment facility, what comes out of your tap has already been through similar steps. In some facilities, several reverse osmosis water filtering systems are used.

If you have well water or another source that is heavily contaminated, you may need a reverse osmosis water dispenser, but first you should have your testing done, to see which contaminants you are faced with. Depending on the level of contamination, you may need a variety of purification steps.

If bacterial contaminants are present, you need a disinfection step. In years past, most homeowners used chlorine for this step, but today a compact ultra violet light is available for a reasonable price.

If chemical contaminants, pesticides like lindane or herbicides like atrazine, are present, you may need a variety of stages to remove them all. The system that removes the most chemical contaminants is a multi-stage device that includes activated carbon and other media in block form to trap chemicals on its surface as the water passes over it.

The best ones target chlorine, THMs, VOCs, pesticides, herbicides, MTBE, TCE and the design is such that microscopic bacterial cysts are also removed. They cannot pass through the sub-micron design of the block.

Some of the new reverse osmosis water filtering systems combine designs like this with their normal membrane filtration. Aware of the things that RO alone cannot remove; they have begun to include additional steps, such as UV disinfection, in order to make a complete home system.

But the question still remains, do you need the RO step, at all. If you are serviced by a treatment facility, the answer is no. In most cases, the answer is that there is a better less expensive alternative.

A countertop reverse osmosis water dispenser costs three times as much as the multi-stage system that I mentioned earlier. For most of us, that multi-stage system is all that is needed. If you actually need RO treatment, it is unlikely that a countertop device would perform as desired.

Since, the only people who need reverse osmosis water filtering systems are those with contaminants larger than water's molecules, in other words, dirt and debris, as would be found in an open source, there is no way that a countertop unit could do the job. It's just too small.

One of the primary disadvantages of a reverse osmosis water dispenser is that the result of use is de-mineralization. A trace mineral content improves taste and is better for your health. Other filters purify, without de-mineralizing. That's the best choice for my family and probably yours, too.
