Lead has debilitating effects on the brain, heart, kidneys and ears. Your water supply must not have any quantity or level of lead. A quality filter and clean water is vital to health simply because of being careful about the presence of lead.


When a filter becomes too old and worn, it will no longer have the ability to filter out the carbon in the water. Thus, carbon will get in the water in high amounts, which is bad for your health.


As a filter wears down, it won’t be able to stop bacteria from entering your drinking water. As bacteria grows, it increases extremely fast, especially if the carbon level is currently high. If there is a high bacterial quantity or specific harmful microorganisms, you can get extremely sick. This could lead to wide range of health problems, beginning with stomach problems, flu symptoms, and many more symptoms.


Chlorine is an important decontaminant for water in public treatment systems. At high levels though, it isn’t safe. It can create a pool-like taste and smell in your water.

A filter will remove chlorine, unless the filter is not longer functioning. The scent and taste of chlorine might be a sign about the age of the filter. Chlorine can cause a burning throat, stomach pain and other ill symptoms.


Volatile organic compounds consist of pesticides, insecticides and herbicides. Each one of these can enter your water supply when traveling from the supplier.


Mercury harms the kidneys, brain and unborn children in pregnant women. In general, mercury must be removed completely from water. Any quantity of it can cause injuries and illnesses. A filter will make sure to remove it entirely.


Asbestos, a product largely located in insulation in building and construction, can enter water in numerous ways. Asbestos can frequently be accompanied by contamination, corroding pipes and industrial waste. Asbestos has considerable destructive results on the respiratory system.
