About Us

At ThinkPure we have been installing water filtration and conditioning systems in eastern Massachusetts since 2011. We are a “boutique styled” local family business and take pride in our expert installations. With a primary focus on residential water, we are familiar with many water quality issues from hard water to microplastics to the presence of dangerous industrial chemicals such as PFAS PFOA. We offer free mineral testing as well as various types of comprehensive laboratory testing for a fee. All whole house systems are installed by licensed professional plumbers. We offer comprehensive regular servicing of all systems we install. Call us for a no charge visit to go over the best solutions for your water quality issues.

This Beacon Hill installation is one of our flagship whole home systems.

This carefully planned out filtration system was installed in a Beacon Hill single family residence. The 5 story building was fully gutted including all structural aspects. The homeowners, already TPW customers, invited us to design and install premium quality filtration. In any major build or remodel, the best results come from early planning.  ThinkPure was able to integrate filtration into early infrastructure and space planning. The “water room” was sized and designed around the filtration system literally down to the inch.

Although we “love that dirty water” you cannot allow even a gallon of Boston MWRA water into a modern plumbing/heating system in a new construction building without at least sediment filtration in place before you turn the water on. Shower heads clog really quickly. Tankless systems can clog in a few months.

The 304 Stainless Steel tanks on the right are 1 Micron followed by .35 Micron 60 GPM sediment filters. Even when loaded with sediment, you still have lots of water pressure and volume.

Next is a bank of 4, NSF Certified Standard 53 Health Rated cartridge tanks. These IAPMO Platinum Awarded filters remove lead, chlorine, chloramine, PFAS PFOA, and a myriad of other impurities at astonishing rates. Lead for example (both soluble and insoluble) is removed from the whole house @ 99.7% which is even higher than Reverse Osmosis. For PFAS PFOA, these quick change cartridge tanks are far  superior to the older “lead-lag” loose carbon tank design for many reasons.

On the left is a 100% US made Axeon 350 GPD Reverse Osmosis filter. Even the critical membrane element is made right here in the U.S. RO lines were run to independent faucets at the kitchen and pantry sinks, the fridge, the under cabinet ice maker and the steam oven.

The RO System features a variable speed delivery pump that insures robust flow rates no matter how many points of use are used simultaneously. We used twin, high grade U.S. made Amtrol storage tanks. RO water is also remineralized and UV sterilized. Multiple TDS meters can monitor total dissolved solids in incoming water, outgoing RO water as well as post remineralized water on the way to points of use.

Another outstanding result of early planning was making sure the water room was cold. Utility rooms with a boiler can reach 80+ degrees so filters should not be in the same room. Not only was the water room kept outside the “heated envelope” of the building, it was independently air conditioned to keep all water in filter tanks really cold. The purest healthiest water always emerges from cold sources in nature.
