In the recent past, we have discussed improvements in traditional water softeners, and the positives and negatives of a few alternative treatment methods. One important theme we have not touched on is drinking water. A reverse osmosis system is a point-of-use filter set which typically installs under the kitchen sink, and is used to feed a separate drinking water faucet at the sink. The quality of the water provided by these units will rival any commercially available bottled water, and is best used for drinking and cooking.

A reverse osmosis filter system makes a great companion piece to finish off your whole house treatment system. The system usually consists of several stages of filtration in order to remove the maximum amount of impurities from your drinking water. The first stage is typically a sediment filter for removal of solid particles, such as dirt or sand, which may be in your water supply. The second stage of reverse osmosis is carbon filtration. The purpose for this stage is primarily to remove chlorine. The main reason for these first two stages is to protect the third stage of filtration from damage.  This stage is called the membrane, and is where the majority of the purification takes place. The reverse osmosis membrane removes up to 99% of chemical impurities from your drinking water. This clean water is stored under pressure in a small tank near the filter system. Just before the water is used, it is forced through the final stage of carbon filtration. This post-carbon is designed to polish the water immediately before use, ensuring that you get the best tasting water possible.

The water provided by a reverse osmosis filter system will greatly improve the taste of coffee or tea, and will eliminate the need for flushing your coffee maker with vinegar, as no build-up will occur.  There are many custom styles and finishes available for drinking water faucets, so matching your existing fixtures is not difficult.  When possible, a line can be installed through cabinets to supply purified water to an existing refrigerator, or ice-maker. A licensed professional can consult with you to ensure your family is drinking the best quality water available.
