Water Treatment Certification: Is it That Important?

Finding quality products in a marketplace flooded with options can be challenging. How can you tell if a product is safe, reliable, durable and capable of meeting the claims made on its packaging and in its literature?

If you’re using a point-of-use water dispenser, it’s a good idea to check on its certifications. Certifications are critically important to the health and well being of your employees and customers.

There are a number of certifications that you will want to look for when choosing a point-of-use water filtration system. Some of the most important include…

  • WQA gold seal
  • NSF/ANSI standards
  • UL Listing
  • ISO standards, and
  • Energy Star

Let’s explain each, to see the criteria upon which these certifications are granted.

WQA Gold Seal

The WQA – or Water Quality Association – is made up of more than 2,500 members around the world. It serves as a resource for public information about water quality and the water industry in general.

The WQA Gold Seal Certification Program is an independent seal of approval showing a product has passed WQA standards, under scientific testing, ensuring a device’s safety.

NSF/ANSI Standards

NSF certification

The acronym “NSF” began as the National Sanitation Foundation in 1944, at the University of Michigan School of Public Health. Today, NSF has joined ANSI or the American National Standards Institute to help oversee water treatment and water distribution products in North America.

Water is tested on a voluntary basis. A complete product review is done which includes testing and evaluation to ensure that the product submitted meets their standards.[1]

The certification process under NSF/ANSI is thorough but also very efficient. A dedicated NSF project manager is assigned as a single point of contact to help a manufacturer through the certification process.[2]

There are a number of NSF/ANSI standards you will want to look for in your water treatment products. Specifically, look for certifications 53, 58, and 42.

NSF/ANSI 42 and 53 have set the benchmark for the integrity and safety of water filters. The NSF/ANSI 42 and 53 certifications include minimum requirements for filtration systems that reduce things like chlorine and other odors in water.

NSF/ANSI 58 addresses such health hazards as lead, organic chemicals and any asbestos that may be present in the water.

UL Listing

The UL listing is something we’re all familiar with – it stands for Underwriters Laboratories. UL tests, inspects and verifies compliance and regulatory issues across the supply chain from manufacturers to consumers.

Having a UL Listing for your point of use water distribution system gives you and your employees the peace of mind that UL has tested that product against its national standards for safety.

ISO

ISO

The ISO, International Standards Organization certification is something else to take into consideration when purchasing a point-of-use water system. The ISO certification has everything to do with environmental impact and performance.

In fact, ANSI is the U.S. member of ISO which makes certification a worldwide goal.[3] There are two numerical standards to pay attention to with respect to ISO and they are 9001 and 14001.

ISO 9001 is an international standard dealing with quality management systems. ISO 9001 is the only standard that’s used for conformity assessment to ensure that the supplier of your water system has met ISO’s stringent safeguards pertaining to management commitment.[4] That commitment involves a manufacturer’s management team defining the processes that meet a customer’s requirements in an efficient and cost-effective way.[5]

ISO 14001 deals with environmental performance and this management tool allows an organization to control the impact of its activities and products in a holistic manner.[6]

Energy Star

Energy Star

The Energy Star label is something we have seen on our appliances for decades now. The Environmental Protection Agency started the Energy Star Program in 1992 to help cut down on computers that were draining energy. [7] This program now covers all sorts of household and office appliances including point-of-use water distribution systems.

This qualification ensures the product you’re using is as efficient and environmentally protective as possible.

Products can earn the Energy Star label by meeting the energy efficiency requirements established for energy savings and verifiable performance.

A great solution to clean drinking water in the workplace is a reverse osmosis system that is certified to all of the certifications previously mentioned, like Pure Water Technology’s 2i & 3i units.
