If you uncontaminated water for your home, there are a wide selection of systems you can choose from. However, it is advisable to do some research before purchasing one. Do you need multiple filters or a model that will filter the water for your entire family? You should also understand how the different types of water filtration systems work.
Opt for a whole house filtration system if you desire to use one unit to filter all of the water for your abode. You have to fix them at the mains that supply water into your home. You can choose from a wide range of systems such as activated carbon filters, steam water distillation systems, reverse osmosis filters, and some others. To add to the confusion there is a point of use models too, which include, water pitchers with included filters, under counter water filters, filters in refrigerators that filter and dispense pure water at the refrigerator door, and countertop water filters. Never purchase units that convert hard water into soft, as they will never purify water.
Let us understand the functioning of the different types of home water filters available and see what the best reverse osmosis system is.
Steam water filters are one of the simplest ones. They work by boiling water in a container that contains a spout at its top, connected to a water collection chamber. These systems work by condensing water vapor in its spout, where the vapors convert to water through condensation and collect in the collection chamber. They remove all impurities from the water, which deposits at the bottom of the container in which the water is boiled. The best part of such filters is that boiling water also kills all germs and other toxins, providing you with pure potable water.
The reverse osmosis functions by forcing high-pressure water via a series of membranes or a semi-permeable membrane. The filtering quality of such filters depends on the size of the pores in the membrane. The smaller the size of the pores, the more contaminates it blocks. However, water filtered through this system may have an odd taste, as chemicals used by the water supply corporation such as chlorine may still remain in the system after passing through the reverse osmosis filter.
The activated carbon filter works on the principle of gravity and no energy is required to operate it. It contains two chambers separated by a layer or activated carbon. When water passes from the top chamber to the bottom through the carbon layer, the latter traps sediments, organic compounds, and microorganisms too. The functionality of this system depends on the layers of activated carbon included.
