FILTER STAGES:

Stage 1: Sediment and Chlorine Reduction Filter 

  Reduces chlorine, bad taste, and odor while capturing fine particles down to 0.5 microns, including cysts like Giardia and Cryptosporidium. This filter is certified to NSF/ANSI Standard 42 and helps ensure your water is safe.

Stage 2: Submicron Filtration with Ion Exchange

  Designed for submicron filtration at 0.2 microns, this stage tackles contaminants like bacteria, viruses, and heavy metals such as lead and arsenic. The built-in silver additive further protects against bacterial growth. NSF/ANSI 42/61 certified.

Stage 3: Advanced Carbon and Nano Filtration

The powerhouse of the PureSync system, this filter uses advanced carbon and nanotechnology to tackle a wide range of harmful contaminants. It has been shown in third-party lab tests to reduce chloramines, lead, fluoride, and volatile organic compounds (VOCs), which can affect both water safety and taste. Tested to stringent ANSI/NSF standards, and will effectively address PFAS, a class of chemicals that many filters on the market struggle to address. It also effectively removes cysts like Giardia and Cryptosporidium, along with pharmaceutical residues and other emerging contaminants. With its high surface area and minimal pressure drop, this filter ensures consistent, reliable, proven performance, making it a critical part of the system’s multi-stage approach to delivering safer, healthier water. Tested To: NSF/ANSI Standard 53 Cyst Reduction. Meets P231 Protocol.

Stage 4: Carbon Polishing Filter

This final stage is designed to enhance water taste and ensuring its overall quality. Using premium coconut-shell carbon, this filter works to reduce any remaining chlorine, chloramines, and volatile organic compounds (VOCs) that might still be present after the initial filtration stages. By maximizing contact time with the water, it efficiently removes lingering contaminants that can impact flavor, leaving your water tasting clean, crisp, and refreshing.

Optional: Inline Mineralizer

While our filters never remove essential minerals naturally present in the water, for customers seeking the added benefits of further mineralization, we offer our optional Inline Mineralizer (purchased separately) is a valuable addition. This add-on gently reintroduces essential minerals like calcium and magnesium, which contribute to improved water taste and support overall wellness. Designed for seamless integration, the mineralizer easily installs in-line after your PureSync system, and offers an easy and effective way to enhance the health properties of your filtered water without affecting flow or quality.

Already a PureSync Customer?

Please Note: While the filters included in our PureSync system undergo rigorous lab testing to meet industry standards, lab tests do not always reflect real-world situations. Water quality can vary based on your location, source, and water usage, which may affect the performance of filtration systems. We strive to provide our customers with the best possible solutions, and our thoroughly-vetted filters ensure that you receive a system designed for effective contaminant reduction.

Filter Replacement Guidance: To ensure optimal performance, filters should be replaced every 6–12 months, depending on your water quality and usage patterns. A simple and cost-effective way to determine when it’s time for a replacement is by using chlorine test strips. If chlorine begins to pass through the filter, it’s a clear indicator that other contaminants may also be making their way through, signaling the need for a new filters.

The filters included in this system are designed for both CITY and WELL water, with no variations required

Advanced Filtration Technology for Superior Contaminant Reduction

The PureSync Undersink Filtration System employs a meticulously engineered multi-stage process, integrating proven and innovative technologies to ensure unparalleled water quality. Each stage targets specific contaminants, delivering precise, reliable results.

 

STAGE 1: High-Capacity Sediment Filter:

The system begins with a sediment filter designed to remove suspended particles such as dirt, rust, and silt down to micron precision. This stage prevents clogging and ensures optimal performance of subsequent filters, prolonging the system’s efficiency and lifespan.

STAGE 2: Compressed Carbon Block Filtration:

The second stage features a high-performance carbon block filter, known for its exceptional adsorption capacity. This filter targets chlorine, chloramine, and volatile organic compounds (VOCs), effectively neutralizing chemical contaminants that affect taste and odor. It also captures heavy metals like lead, ensuring the water meets stringent safety standards.

STAGE 3: Nano-Enhanced Filtration Technology:

At the heart of the system lies an advanced nano-filtration stage, leveraging cutting-edge nanotechnology to address emerging contaminants. This stage is particularly effective in reducing pharmaceuticals, PFAS (per- and polyfluoroalkyl substances), pesticides, and other micro-pollutants that standard filters cannot adequately remove. The nano-filtration technology operates at a molecular level, delivering high-precision contaminant reduction while maintaining water flow rates.

STAGE 4: Inline Granular Carbon Polishing Filter:

The final stage employs a granular activated carbon filter to provide a finishing polish to the water. This step ensures any residual impurities, including organic byproducts, are removed, leaving your water clean, fresh, and ready for use.

OPTIONAL – In Line Mineralization:

The PureSync system preserves all naturally occurring minerals in your water, ensuring no beneficial elements are removed during the filtration process. The optional mineralization module is available for customers who prefer the enhanced taste and added trace minerals like calcium and magnesium. This feature is purely a preference for those who enjoy the subtle flavor profile and potential health benefits of mineral-enriched water, delivering water with a balanced pH and a crisp, refreshing taste.

Certifications and Standards:

The entire system is designed in compliance with NSF/ANSI certifications (42, 53, and 61), ensuring independently verified performance and safety. These standards confirm the system’s efficacy in contaminant reduction and structural integrity, providing peace of mind with every drop.
