Common Water Pollutants and the Decay of Our Health

Our need to stay hydrated in order to survive confronts us with a harsh reality – considering how much our health is negatively influenced by the pollutants that lurk in the water we drink. There is no mystery to the fact that bottled water does more harm than good, and seeing how tap water is an even worse source of getting hydrated, it might seem like there is no solution to our problems.

Under sink water filtration systems present the ideal way to stay hydrated without endangering your health as these filters make it a point to remove unwanted and harmful contaminants, leaving behind clean and safe water for consumption. Learn more about the common pollutants that all top of the line water filters eliminate and how their presence in tap water could affect your health by reading the following lines.

  • Chlorine: This chemical is all so present in our drinking water as it has the capability to disinfect it and keep dangerous bacteria, like giardia and E-coli at bay. However, exposure to chlorine on a daily basis and its regular consumption through water can take a toll on your health. If you are lucky, you will only get a rash or irritation caused by bathing in the water. In case your health is on the fritz and luck is not your strong point, you could even have cardiovascular issues or become predisposed to cancer.
  • Lead: This is a dangerous and persistent contaminant that can take a toll on your health in the long run. The bad news is that it has an almost immediate negative effect on children’s health, so if you are a parent, you cannot afford to take risks and get the small one sick. The effects of lead contamination on your health include impaired hearing, damage to the central nervous system, impaired function of blood cells, and so on.
  • Mercury: Poisoning with this harmful contaminant leads to unwanted health effects that include impaired speech, impaired hearing, impaired walking, muscle weakness, loss of peripheral vision, lack of coordinated movements, and so on. One of the most powerful and dangerous pollutants to reside in tap water, it must be eliminated in order to ensure your well-being.
  • VOCs: VOCs or volatile organic compounds is a term applied to a broad category of chemicals, either man-made or natural. When volatile organic compounds found in drinking water reach alarming levels, your health is the first one to receive a downgrade as their toxicity exposes you to the apparition of various forms of cancer, nervous system problems, and kidney health issues.

With a maximum feed temperature of 90 degrees Fahrenheit and a system capacity rating of 600 gallons, the Aquasana AQ-5300.62 is inevitably the number one pick when it comes to under sink filtration systems. Furthermore, its list of pros does not end there as it is actually able to eliminate up to 70 different contaminants, passing the water through 3 separate filtration stages. Aside from this top quality system, another entry which blew us away with its stats and capabilities is the Pelican Water PDF-1500-PC which has a generous 1500-gallon capacity and requires filter replacement only 1-2 per year. However, if you are faced with severe problems in terms of water contamination, we recommend you opt for the APEC Essence ROES-50 or the iSpring RCC7 as both systems can remove over 1000 contaminants.
