Welcome to RO-System.org, where we don’t just help you to find the best water filter system…  We help you get the peace of mind that you and your family are drinking the cleanest and purest water.

Why RO-System.org?

Unfortunately, the water that you drink and cook with in your home can have some surprising ingredients, regardless of how good it looks, smells, or tastes.

It doesn’t matter if you have a well or municipal source, your water is not perfectly clean.

Even if you spend money on bottled water, you may not be getting something that is better than your own tap.

According to the Environmental Working Group’s (EWG) Tap Water Database:

  • 81% of American’s water contains contaminants linked to cancer
  • 77% of Americans are drinking hexavalent chromium (the “Erin Brockovich” chemical)
  • Water samples from all 50 states have been found to contain: arsenic, chromium-6, disinfection byproducts, lead, nitrates from fertilizers, and radiological contaminates.

In addition, 85% or more of Americans deal with hard water that causes problems of its own.

Since you can’t choose the source of water that comes to your home, the only way to ensure the quality of your tap water is to filter it.

How RO-System.org helps

Like many things in life, making the right choice about a water filter can be confusing, time consuming, and frustrating.

RO-System.org makes the process of choosing your water filtration system easy by reviewing the top systems that are effective, popular, and easy to get. 

We then rank them based on their features, teach you what all of the terms mean, and suggest which systems would be the best for your situation, water, and budget.

Whether you want to improve your own health, the health of your children, or even the health of the fish in your aquarium, a water filter system is an extremely effective and relatively inexpensive way to ensure that one of the most crucial ingredients in your kitchen is clean and safe.
