WQA Information

The Water Quality Association (WQA) is a not-for-profit association for the residential commercial, and industrial water treatment industry. WQA represents more than 2,700 member companies around the globe. Our membership is comprised of equipment manufacturers, suppliers, dealers and distributors of water quality improvement products and services.

WQA proudly serves as an educator of water treatment professionals, certifier of water treatment products, public information resource and voice of the water quality improvement industry.


WQA is a resource and information source, a voice for the industry, an educator of professionals, and laboratory for product testing.


The Water Quality Association was created in 1974 from the merger of two trade associations, Water Conditioning Association International (representing water treatment equipment dealers) and the Water Conditioning Foundation (representing water treatment equipment manufacturers and suppliers).


WQA Product Certification (Gold Seal) Information

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 literature?

WQA's Certified Product Listings are available to help connect consumers with water treatment products that have been tested and certified to industry standards. WQA's Gold Seal Product Certification Program ensures that the product is constructed or formulated from safe materials, the claims listed on the packaging are backed by test data, and the product will hold up under normal usage conditions.

WQA maintains a complete listing of all products and components that have earned the Gold Seal and Sustainability Marks. Only products that pass the rigorous testing requirements of industry standards, pass annual manufacturing facility audits, and comply with WQA's Certification Schemes can be found in this listing.

Benefits of Gold Seal Product Certification

Peace of Mind - WQA Certification provides end users, retailers and regulators the benefit of knowing that the an accredited third party has eva luated not only a product’s capability of passing rigorous testing according to industry standards, but that the process in which certified products are made is reproducible.  This process allows users the peace of mind that a company is continuously monitored and can only maintain certification if their manufacturing process remains consistent.

Multi-faceted Certification - Not only are the products tested extensively to eva luate things such as the structural integrity, the product’s ability to reduce contaminants and the safety of the materials that come into contact with water, but the literature is also reviewed to ensure that it meets a specific set of requirements as well.      

Buying Power - A certified product bears a distinguished Mark indicating that the product has undergone eva luation and testing to verify that the product will perform as the certified claims indicate.  The Gold Seal and Sustainability Mark provide consumers a very simple way to recognize products that will perform the way the packaging indicates it will.

Consumer Protection – There is no doubt that the infrastructure for most municipalities is old and requires billions of dollars of upgrades.  While the facilities themselves provide water that in many cases exceeds drinking water requirements, the path to the end user is not always as exemplary.  Final Barrier is a solution to this problem.  Certified products allow for consumers to target the specific contaminant issues with confidence that the product does what it claims it will do.

Regulatory Requirements – Some states or local cities have specific regulations in place that require certification for the ability to sell legally in that jurisdiction.  CA has passed new legislation that will require an ANSI accredited certifier issue certification to products making health claims before they can be legally sold in CA.  If a products is certified by WQA, you can be assured that it will also be safe for purchase in California.

Monitoring Consistency – WQA’s programs do not issue certification and allow for that certification to remain untouched indefinitely.  The programs conduct annual inspections to verify that the products being manufactured are not only being consistently made, but are made in the same way as the product was built when it underwent testing and eva luation. 


WQA Professional Certification and Education

The WQA Professional Certification program helps consumers and employers identify individuals in the point-of-use/point-of-entry water quality improvement industry who have demonstrated a certified level of professional expertise and are dedicated to high professional standards.

WQA certification is a voluntary credentialing process. To achieve any WQA-certified title, the candidate must pass a comprehensive exam and accept the WQA Code of Ethics for the Water Quality Improvement Industry.

As of March 2015, candidates for certification must complete the Foundational and relevant Core curriculum in the Modular Education Program.
