Everyone wants clean water with a good taste, as far as drinking water is concerned. A water filter is a tool for families at home that provides them with good quality clean water that is free of chemicals, odors, and other toxic substances. Even though many of the water filters look similar, there are notable differences between many forms of water filters.
If you want to purchase water filters for your office or home, this article will help you know the different types of drinking water filters and their functions.
Water Filters
Before buying any kind of water for drinking purposes, whether a water cooler, a jug from a store, or a filtration system, it is good to have an understanding of different purification techniques that may take place before you take a sip of water.
Some filtration techniques are more efficient at removing impurities and particles than other methods. Here is the overview of the top three water filtration methods.
Reverse Osmosis (RO)
Reverse Osmosis is an effective method for the elimination of high concentrations of toxins such as hexavalent chromium, fluoride, arsenic, copper, salt, radium, nitrates/nitrites, as well as dangerous waterborne bacteria.
The reverse osmosis process works by forcing the water through a semi-permeable membrane with the help of pressure. The membrane only allows water to pass to the other side and impurities remain on the membrane.
Reverse Osmosis systems are gaining much popularity but they use an excessive amount of water i.e. more than four times the standard amount. The reverse osmosis process is quite slow and causes a reduction in water pressure.
This is the reason why the reverse osmosis system for the whole house usually doesn’t exist. Moreover, this filtration level is not required for all daily activities like taking showers, flushing toilets and doing dishes.
Activated Carbon
Activated carbon tends to remove impurities by forming chemical bonds to the water that is added into the filtration system.
Some of these filtration systems can effectively remove chlorine, which others only enhance odor and taste, still, others only eliminate harmful substances, like lead and mercury.
It is essential to keep in mind that activated carbon filters can’t remove inorganic substances including arsenic, fluoride, and nitrates.
Distillation
Distillation, being one of the oldest purification techniques, involves heating water to a very high temperature until it vaporizes. The vapors generated are condensed back into the liquid state. This water is the purest and anyone can drink it.
The distillation process gets the water rid of microorganisms, minerals, and harmful organic and inorganic chemicals, and heavy metals as well. Distillation also kills all the pathogens and bacteria that are responsible for making people sick. Distillation will not eliminate chlorine and other volatile organic chemicals.
This water purification technique is the most natural as it doesn’t involve any addition of chemicals to the water. It eliminates natural impurities and all those injurious heavy metals in the water, thus making it one of the best drinking water filters to buy for home or office.
