Water Filtration Guide
Seven types of filters can be used to filter water in homes.
Which filter you should use depends upon the quality of water you’re having in your area.
Reverse Osmosis or RO water filters are designed to remove almost 90% of total dissolved solids or TDSs from water and can filter the purest water for the home.
Reverse Osmosis filters are capable of removing many minerals and contaminants from water including sand, chlorine, fluoride, cryptosporidium, and hexavalent chromium from drinking water.
Undersink water filters can remove contaminants from the water in the same procedure as RO filters.
But, they leave some essential minerals like calcium and fluoride in water.
Undersink water filters are more beneficial than RO as they are easier to maintain.
They have a higher flow rate and water pressure and also they do not produce wastewater.
Ultraviolet water filtration is proved to be more beneficial in killing germs and chemicals present in water.
UV filtration is very impressive in getting water for drinking and cooking purposes as the water filtered through this process is more clean and healthy.
Countertop water filters are used for home water filtration and are inexpensive and easy to use.
These systems are very easy to install anywhere and use granular activated carbon or GAC media, KDF media, carbon block cartridges, or ceramic cartridges to filter water.
Portable gravity water filters are very effective in eliminating water-borne diseases such as cholera, typhoid, E.Coli, etc.
They are majorly used by organizations in areas where these diseases are found.
These water filters can easily be used in such areas due to their portability and capacity to clean lakes and river water.
Bottleless water filtration systems can be installed in any of the above filtration systems.
They provide the same services as bottled filtered water.
These filters can be used according to the hot or cold temperature of the surroundings.
