There are different technologies in use today for water filters. Carbon is the most commonly used in home water filter systems. Carbon can absorb different types of contaminants. In addition to filtering chemicals, carbon is used to filter various types of organic materials such as inorganic minerals such as calcium and magnesium. In addition, carbon is used for separating different gases such as carbon dioxide, nitrogen, oxygen, and sulfur among other gasses. more info here
Today, there are also different kinds of filters such as reverse osmosis and distillation. Reverse osmosis filters use semi-permeable membrane to filter impurities such as larger particles of dirt and microorganisms. On the other hand, distillation is a method of using pure steam to vaporize impurities. This process of water filters purifies water by removing chemicals, volatile organic compounds (VOCs), salt, and various types of minerals.
Your water filter pitcher has to be able to filter out a gallon of water at a time, or you are going to be wasting money. Most water pitchers can handle up to four gallons of liquid at a time. There are even some that will come equipped with a dispenser for the pitcher, if you buy one that comes with that feature.
The best filter system for your home. There are so many options to choose from, so let’s start with the basics. Water that is purified with reverse osmosis or other methods will remove fluoride and copper, but it will leave the important trace minerals like calcium and magnesium. Gravity-fed filters use a combination of carbon and/or ceramic filtration to remove these minerals. The best water filters use both types of filtration to ensure that you get the purest water possible.
