When it comes to water filtration there are a lot of options on the market. A basic carbon media based filtration system can help remove a wide range of contaminants from your drinking water, but the best home filtration option is the RO water purifier. These systems offer incredible filtration quality and are basically the most efficient filtration option short of distillation, though distilled water lacks the essential minerals that our bodies need. When you buy an RO water purifier for your home, you are making an investment in clean and refreshing drinking water for your home.

Reverse osmosis, if you have not already guessed, is the natural process of osmosis in reverse. Osmosis is the movement of a solvent, like water, through a semipermeable membrane in order to achieve a balance of dissolved solids on both sides of the membrane. Basically if water on one side has more dissolved solids than the other, then water will move towards the more concentrated side until balanced concentrations are reached on both sides.

The ability for water to travel in this manner is limited by the osmotic pressure of the membrane. By overcoming this osmotic pressure on one side of the membrane, you can control the flow of water. Starting with contaminated water on one side and pressurizing it will create pure drinking water on the opposite side and wastewater with a high concentration of dissolved solid on the original side. The RO filter membrane is extremely fine so it can remove particles much smaller than a conventional carbon based filter cartridge.

Sadly these membranes are delicate, which is why most RO systems require some level of prefiltration. This first step of filtration helps to remove large particles that might clog the membrane and chlorine that can eat away at the membrane material. Some systems even include a third level of filtration to help remove any small volatile organic compounds that might have slipped through the membrane.

The RO filtration process is not without its downsides. These filters are typically larger than your average filtration system, typically occupying a large percentage of your under sink space. Because the RO purifiers work a little slower than carbon filters, most RO water filters include a storage tank to ensure that clean reverse osmosis water is always available when you need it.

If you are looking for a reliable home RO filter system, the new Everpure ROM IV filtration system is an incredible option. Not only does it provide incredible water quality, but it also removes harmful contaminants like heavy metals so you can rest assured that your family will have safe drinking water.
