Centuries of Water Filtration Expertise.
At Doulton we have been perfecting our water filter systems since 1826. Combining traditional methods with modern innovation, our team of experts provide water filtration solutions from our UK manufacturing and testing facilities to households around the world.
Pioneering Water Excellence Since 1826
Rooted in the pioneering spirit of John Doulton, our journey began in Britain with a simple yet transformative mission: to enhance water quality naturally and sustainably. Over two centuries, Doulton has led the way in water filter technology, marrying traditional craftsmanship with innovative solutions.
As we embrace the future, our rich legacy remains our compass, inspiring us to innovate for a healthier world. With Doulton, experience better drinking water in your home.
Rigorous Testing Standards
Our commitment to delivering water at its best is underpinned by a meticulous testing regime that sets us apart. Our dedication to quality and safety is not just a promise but a practice, evidenced through rigorous, scientific testing procedures.
From our in house laboratories to real world applications, our team of experts employ the latest in water science and technology to ensure our filters meet and exceed global standards. This is proven through accolades such as our NSF Certification.
Transparency in Every Drop
Doulton water filter systems can reduce up to 99.99% of common contaminants, a claim that we back openly for everyone to see. Details of our testing processes and results are openly shared, providing you with the confidence that choosing Doulton means choosing a legacy of quality tested through time. All of our certifications can be easily found, and you can see an overview of our test data on this page.

Certification and External Validation
Certification and External Validation
We adhere to globally recognised certification protocols to validate the performance of our filters. Beyond internal testing, we engage independent laboratories to test and certify our products, ensuring unbiased verification of our claims. This includes NSF and WRAS approval.
Microbiological Testing
Microbiological Testing
Our filters are rigorously tested against bacteria and cysts (including Cryptosporidium) to ensure effective reduction rates. Using protocols aligned with international standards, each filter is challenged with specific microbiological contaminants to verify its efficacy.
Chemical Reduction Tests
Chemical Reduction Tests
To assess the effectiveness in reducing chemical contaminants like chlorine, lead, and pesticides, we ensure our filters are tested with the volume of water we claim they can work at and then we test to understand the removal/reduction %.
Flow Rate and Capacity Evaluation
Flow Rate and Capacity Evaluation
Efficiency in water filtration is not just about contaminant levels with a small amount of water but also about performance over time. Our filters are tested for optimal flow rates and long-term capacity, ensuring they deliver efficient water filtration throughout their lifespan.
Particulate Removal Efficiency
Particulate Removal Efficiency
We test the removal of fine particulates, including microplastics, to enhance the overall quality and taste of the water. These tests ensure that our filters effectively reduce even the smallest particles. The following products are NSF certified for the reduction of Microplastics: Biotect Ultra, Biotect Ultra SI, Ultracarb & Ultra Sterasyl.
Addressing Cocktail Testing
Cocktail tests are a quick way of understanding what can be filtered with, usually a small volume of water. You will find some water filter companies will use 'cocktail testing' in their marketing to make claims about the amount of contaminants their filters can remove. Doulton do not use cocktail testing as part of their marketing or test data literature. Our tests precisely measure the filter’s performance against each specific contaminant and with the lifetime water capacity of the product. All of our results are quoted based on this approach. If we quote a reduction % you can be sure it’s based on the overall capacity we quote for the filter. This method provides a more accurate and reliable indication of each filter’s capabilities and do not over exaggerate claims.
