Health authorities always issue warnings about waterborne diseases that can be contracted by drinking or using water contaminated with pathogenic microbes. 
Take note that waterborne diseases are more serious than infections, as pathogens cause impairment of vital bodily functions or systems once they invade, multiply and become parasites inside the body. So we shouldn’t be surprised why most people use a water filtration system to further decontaminate water supplied by a utility company and coming out of faucets.
To be clear, the water provided by utility companies undergo several chemical processes to separate and suspend particles and sediments, as well as subject the water to chemical treatment to kill different types of microorganisms thriving in the water but unseen by the naked eye.
Ordinarily, members of households use tap water for drinking, for washing raw and fresh ingredients, for making beverages, for boiling and overall cooking processes. However, we cannot be hundred percent sure that the water coming out of faucets is clean. As water traveled from treatment facilities to communities, they had to pass through storage tanks and piping systems that we cannot say for sure are totally free from contamination. Especially nowadays when strong and heavy flooding can cause underground pipe damages and clogged drains.
What Exactly Can Water Filtration Systems Do to MakeTap Water Clean and Safe to Drink
A water filtration system may be a stand alone appurtenance such as a water filter pitcher or as point-of-use water filters that can be installed in kitchen sinks, on countertops or under the sink. W water filtration system uses activated carbon or reverse osmosis methods in removing a diverse range of contaminants, sediments and pollutants.
The filtration methods are also designed to work on microorganisms that may be thriving in biofilms inside water tanks and pipes but carried away by the strong water pressure that causes water to surge and flow toward specific destinations covered by the water supply system. .
How Does Reverse Osmosis Work as a Water Filtration Method
Reverse Osmosis or RO, is a water filtration process that applies water pressure in forcing water molecules to move inside a semipermeable membrane. As only the liquid water molecules can enter the membrane, the solid contaminants are filtered out and flushed away during the treatment process. Duly approved RO systems can also remove metal ions and aqueous salts formed by chemical contaminants like arsenic, chloride, copper, chromium and the likes.
How Does Carbon Filtration System Work as a Water Filtration Method
Better known as Granulated Activated Carbon (GA), it’s an alternative water filtration method for removing chemicals and other pollutants that give water coming out of faucets, its unpleasant taste and odor.
The Centers for Disease Control states that manufacturers of water filtration systems cannot fully guarantee that their system can remove and eliminate all water impurities and contaminants, even if approved by the National Sanitation Foundation (NSF).
Clearly filtered, a manufacturer of water filtration systems for households, states that its NSF certified Affinity® Filtration Technology, is capable of removing up to 99.9% of all types of diverse water contaminants. What is notable about the Clearly Filtered brand is that it comes with assurance that its proprietary water filtration system is also capable of retaining the essential minerals and nutrients that make the water not only safe but also healthy to drink.
