Why Do I Need a Countertop Filter?

Though tap water goes through the normal chemical process before getting to our homes, it is not always safe to drink. Statistics show millions of US citizens are exposed to unsafe water every year. Though the problem is prevalent in rural areas, a few cities report such cases from time to time. Some contaminants in tap water make it unsafe for human consumption.

One way in which drinking water gets contaminated is through local land usage. For instance, some of the pesticides that farmers use on their farms tend to leak into water sources leading to contamination. Apart from that, manufacturing processes such as sewer overflows and malfunctioning septic systems also lead to the contamination of drinking water.
