PUR Sets New Water Safety Bar With First Filter Certified for PFAS, Lead & Microplastics

BOSTON, MA – September 15, 2026 – In a move that directly addresses a growing trifecta of public health concerns, water filtration company PUR announced today that its PUR PLUS™ line of filters is now certified to reduce lead, microplastics, and a wide range of PFAS “forever chemicals.” The certification makes PUR the first and only brand to offer a single, certified solution for these three specific contaminants across its pitcher, dispenser, and faucet-mounted products, setting a new benchmark in the increasingly competitive home water filtration market.

This development arrives as consumer awareness and regulatory scrutiny of invisible threats in drinking water reach an all-time high. For years, Americans have been forced to triage their concerns, choosing filters that might tackle lead from aging pipes but not the emerging threat of industrial chemicals. With this announcement, the choice becomes substantially simpler.

“People are increasingly concerned about the quality of the tap water they use and consume every day,” said Erin Yarbough, Director of Brand Marketing for PUR, in the company's announcement. “With PUR PLUS, we’re making it easier to enjoy better-tasting water while getting certified filtration against the three contaminants consumers most care about.”

A New Standard in Contaminant Reduction

The significance of PUR's announcement lies in the rigor and breadth of its new certification. Issued by IAPMO R&T, a respected third-party certification body, the products were tested against stringent NSF/ANSI standards. These standards are the bedrock of trust in the water treatment industry, providing independent verification of a product's performance claims.

The certification covers three key standards:

• NSF/ANSI 53: This standard addresses contaminants with known health effects, which in this case includes lead and specific PFAS compounds.
• NSF/ANSI 401: This standard targets emerging or incidental contaminants, including certain pharmaceuticals and chemicals that are increasingly found in water supplies.
• NSF/ANSI 42: This standard covers aesthetic effects, ensuring the filter also improves the taste and odor of water by reducing elements like chlorine.

What makes this certification a market differentiator is its comprehensive nature. The PUR PLUS Pitcher & Dispenser Filter is now certified to reduce 99.9% of lead, 99.8% of microplastics, and 99.75% of Total PFAS. Similarly, the faucet-mounted version is certified for 99.70% of lead, 99.65% of microplastics, and 99.92% of Total PFAS. The term “Total PFAS” is crucial; it refers to a mixture of seven different per- and polyfluoroalkyl substances, including the notorious PFOA and PFOS, providing broader protection than filters that only claim reduction of one or two specific compounds.

Responding to a Rising Tide of Concern

This product evolution is not happening in a vacuum. It is a direct response to a well-documented surge in public anxiety and a rapidly changing regulatory landscape. PFAS, a class of thousands of man-made chemicals used for decades in products from non-stick pans to firefighting foam, are called “forever chemicals” because they do not easily break down in the environment or the human body.

In April 2024, the U.S. Environmental Protection Agency (EPA) finalized the first-ever legally enforceable national drinking water standard for several PFAS compounds, a landmark decision that validated long-held fears about their health impacts. Research has linked exposure to certain PFAS with increased cancer risk, developmental issues, and immune system disruption. A 2023 U.S. Geological Survey study estimated that at least 45% of the nation’s tap water contains one or more of these chemicals, moving the problem from a theoretical risk to a household reality for millions.

Alongside PFAS, the insidious spread of microplastics has captured public attention. These tiny plastic particles, shed from synthetic textiles, tires, and degrading plastic waste, are now ubiquitous in our air, food, and water. While the World Health Organization has stated that current levels in drinking water don't appear to pose a health risk, it has also called for more research, and the long-term health consequences remain a significant unknown and a source of consumer worry.

PUR's own research confirms this anxiety. A national survey conducted by the company in August 2026 found that 79% of adults would be extremely or very concerned about lead in their tap water, with PFAS close behind at 74%. When asked what they valued most in a filter, consumers ranked lead, microplastics, and PFAS as their top three priorities.

Raising the Bar in the Filtration Wars

The home water filtration industry is a crowded space where brands battle for consumer trust. For years, the market leaders, including PUR, Brita, and ZeroWater, have competed on metrics like chlorine reduction, taste improvement, and, more recently, lead filtration.

PUR's new triple certification fundamentally alters this competitive landscape. While competitors offer filters certified for lead or specific PFAS compounds, none have previously marketed a single, unified certification from a body like IAPMO R&T that covers lead, microplastics, and Total PFAS across the most common filter formats. This “first and only” claim provides a powerful and easily understood marketing message that could disrupt consumer purchasing patterns.

Industry analysts suggest this move will likely pressure competitors to accelerate their own research and development and seek broader certifications. The bar for what constitutes a “premium” filter has just been raised. For consumers, this heightened competition is a net positive, likely leading to more innovation and greater transparency across the board. The focus now shifts from simply improving taste to providing verifiable protection against complex chemical and physical contaminants.

With its products available at major retailers like Walmart, Target, and Amazon, PUR is making this new level of filtration widely accessible. The company's decision to provide complete performance data sheets on its website further underscores a commitment to transparency, allowing consumers to verify claims for themselves. For now, the ability to address lead, microplastics, and a wide swath of 'forever chemicals' with a single, certified filter marks a pivotal moment for an industry built on peace of mind.
