Have you ever found yourself wondering what's really in your tap water? Do you often buy bottled water because it's cleaner? It's perfectly normal to feel concerned about the quality of your water; clean water is essential, after all. But this doesn't mean that you have to constantly spend money on plastic bottles or drink questionable tap water. Investing in an under-sink filtration system is an easy way to always have clean drinking water right from the sink. Below are some of the features of the best under-sink filter for cleaner, tastier water:

Express Water Reverse Osmosis Filtration System

For truly purified water, Express Water offers the best under-sink filter. While they have several different options available, the 11-step system provides reverse osmosis (RO) filtration, ultraviolet (UV) sterilization, and alkaline mineralization. Reverse osmosis is a process in which contaminants, such as heavy metals, nitrates, and pharmaceuticals, are removed by pushing water molecules through a membrane at high pressure. Its UV sterilization feature kills bacteria within the water. Finally, alkaline mineralization enhances the water with essential minerals, oxygen, and antioxidants. To top it off, all of this happens right under your kitchen sink!

  • Positive pH
  • UV sanitization destroys E. Coli, Giardia, Coliforms, and more
  • Alerts you when you need to replace the UV filter

Express Water has even included an installation video guide on its website, and each filter includes lifetime support from the company. Once you have it installed under the sink, you can have peace of mind in knowing that your family has access to safe, enhanced water.
