Renovating Your Kitchen? – Water Filters and Reverse Osmosis Systems

Water filtration systems have become a standard fixture in most kitchens today, especially as more and more scientists and health professionals report that most if not all of our drinking water supplies are contaminated with human-made pollutants, including not just municipal systems, but wells, lakes, rives, and glaciers. Unfortunately, bottled water has been shown to have its own host of problems, including serious health and environmental effects. However, while a good water filtration system is the best way to ensure healthy and safe drinking water, it’s not enough to install just any filter in your home. Though the purpose of any water filtration system is to improve the quality and taste of drinking water, there is a wide range of filters available, each with varying costs and effectiveness. The process of planning a kitchen renovation is a perfect time to consider the different water filter options. Some of the most popular filters are explained below to help you choose the best water filter for your home.

Reverse Osmosis
Reverse osmosis is one of the most effective filtration methods available today. Even though the process has been known for over 100 years, it wasn’t until the 1950s that the U.S. government developed it as a way for the Marines to desalinate water to make it drinkable. By way of brief explanation, “regular” osmosis occurs when molecules pass through a permeable membrane to equalize the concentration of molecules on both sides. As its name implies, reverse osmosis is when the opposite occurs. Instead of equalizing the concentration of substances on both sides of the membrane, water pressure pushes pure water on one side of a membrane, leaving a concentration of pollutants on the other.

Reverse osmosis typically also employs two carbon filters and/or other pre-filters, which work to remove a wide range of dangerous contaminants, including lead, mercury, and arsenic. Reverse osmosis is also effective at removing virtually all pharmaceutical drugs, coliform water softener making loud hissing noise bacteria, E. coli, percolate, VOCs, viruses, fluoride, chlorine, chloramines, herbicides, pesticides, cryptosporidium, THMs, and MTBEs. In fact, while typical faucet or counter top filters are 1 stage filters, meaning they have only 1 basic carbon filter, reverse osmosis systems typically offer a 5 stage filtration system. Furthermore, while countertop filters have a 1-5 micron rating, which means contaminates smaller than 1 micron (such as asbestos, insecticides, may not be filter out), a reverse osmosis filter typically holds a micron rating of.0001. While reverse osmosis systems can cost more upfront, their filters only need to be replaced once a year, whereas counter top filters need replacing every couple of months.
