Purchasing a water filtering system can be an overwhelming chore, given all the types of water filters available on the market. However, after a few investigations on the pros and cons of water filters and discovering what type of filter you and your family need, choosing the best type of water filter is more of a personal matter. Here are some particularities of several types of water filter that can help you decide which type is the best for you.
Which type of filter is best for you?
Before buying a filter, it is essential to read some reviews. Water filters all apear to be similar but only a trained eye cans pot the differences that matter. Check out the reviews on waterfilters.systems if you want proffesional opinions on the best water filters. Nevertheless, aside from reading reviews, you also need to understand a few things. Although there are hundreds of brands of water filters for home, they are all based on a small number of technologies to remove impurities. That does not mean that every filter that uses a certain technology is as good as another, but it means that you can easily make a good idea on the general pros and cons of different systems. Depending on the technology they use, water filters are grouped in several categories.
Active carbon filters eliminate some of the contaminants that run through them, such as chlorine, asbestos, mercury and several volatile organic compounds. This type of filters is divided into other two types, namely carbon block and granular activated carbon, the first ones being more effective because of their larger surface. The carbon filter is the most wanted water filtering system, due to its efficiency on a large scale.
Reverse osmosis filters
This process pushes water through a semi-permeable membrane that blocks particles larger than water molecules. Reverse osmosis can remove many contaminants that are not removed by activated carbon filters, including arsenic, fluoride, nitrate and perchlorate. However, reverse osmosis does not remove chlorine, trihalomethanes and volatile organic chemicals and many reverse osmosis systems include activated carbon components that can eliminate these other contaminants.
Ceramic water filters
Ceramic filters have very small holes along the solid material that blocks contaminants such as cysts and sediments, but they do not remove chemical contaminants.
Deionized water filters
These filters use an ion exchange process to remove mineral salts and other electrically charged molecules in water. The process can not exclude the non-ionic contaminants including trihalomethanes and other volatile organic compounds common or microorganisms.
This technology heats the water enough to vaporize it and then condenses the steam back into water in order to remove minerals, bacteria and viruses, and chemicals that have a higher boiling point than water. However, the distillation filters can not remove chlorine, trihalomethanes and volatile organic chemicals.
UV water filters
These systems use ultraviolet light to kill bacteria and other microorganisms, but they can not remove chemical contaminants, which makes them less efficient and wanted.
