An increasing number of consumers are focusing on their drinking water, which means there is a greater need for an independent organization to help people find the “best” water filter for their home’s drinking water. In fact, according to recent study, a majority of consumers believe that water problems are a major crisis in the U.S.

Many people want to find a water system without the pressure of a salesperson pushing their product, even when they feel unsure about what kind of filter they want or need. What NSF International does is provide this assurance to consumers through our independent certification of water filters, purifiers and treatment systems.

A mother of three living in a city has drinking water filter needs that are different from a single person in an apartment building or a family of five with well water. Understanding consumers’ needs helps NSF International help you find the best filter system for your home’s drinking water. Many people ask “What is the best system for getting rid of everything in my water?” Finding a water filter that will do what you need it to do is challenging.

One important question to consider as a first step is what kind of system or filter will work with your home. For example, take the person living in a multi-family or apartment building where they cannot make changes to the plumbing. This is a challenge because installing a reverse osmosis system with a separate tap is not an option. They would have to consider something more portable like a water pitcher with filter, faucet filter or countertop-type filter. Another example is the situation where the drinking water is from a well and there are concerns with nitrate. The only systems NSF International certifies to reduce nitrate are reverse osmosis systems. In this case, the ability to reduce nitrate would be the deciding factor in finding the “best” water filter.

As NSF International’s consumer information specialist, I offer assistance to the public with finding an NSF International certified water filter or system based on their needs. NSF International’s expertise in certified water filters and water treatment spans over 35 years. The consumer resources section of NSF’s web page has a lot of helpful information for learning more about this process of choosing a water system.

Over the last five years, NSF International has answered 48,729 consumer inquiries, 25 percent of which were in regard to water filters and water treatment. In the first month of 2018, we have already assisted almost 150 people with their questions about water filters. Our scientists and committee members (industry, regulatory, consultants and the public) are continually evaluating new contaminants and water technology so that products are certified against a rigorous standard providing assurance that the filter or treatment system will reduce the contaminant to a safer level and be safer to use.

Many one-stop resources or consumer-friendly web pages that help people find a water filter are retailers trying to “sell” you their product. NSF International is an independent not-for-profit organization providing information to help you find the best water treatment or purification system for your home’s drinking water. Through our certification, we provide assurance that a filter certified by NSF will work, is safe to use and reduces the contaminants it is certified to reduce.
