Everpure

Everpure was founded in 1933 by C.B. Doty, who commercialized a proprietary bacteriostatic filtration media that used activated carbon with silver to inhibit bacterial growth within the filter itself. This technology, branded Micro-Pure, addressed a specific operational pain point for restaurants and soda fountains: water impurities that altered the taste, odor, and appearance of mixed beverages. The firm established its manufacturing base in Hanover Park, Illinois, and built its early reputation by solving consistency problems for regional bottlers and nascent fast-food chains. The company pursues a focused industrial strategy centered on proprietary point-of-use water filtration. Its core asset is the Micro-Pure media formulation, which combines activated carbon, silver, and mechanical filtration to remove chlorine, particulates, lead, and volatile organic compounds while limiting bacterial colonization. Everpure supplies finished filter cartridges and integrated system heads to commercial kitchens on a recurring-replacement model. Confirmed end-users include McDonald's worldwide restaurant network and the majority of Starbucks corporate-owned locations. Geographically, Everpure distributes across North America and into key Asia-Pacific markets, with a particularly dense footprint in China's branded-coffee sector. Everpure operates today as a subsidiary of Pentair, a publicly traded water treatment conglomerate that acquired the brand in 2004. The acquisition folded Everpure's foodservice channel into Pentair's broader commercial and residential water solutions portfolio. While Pentair does not break out Everpure-specific revenue, the parent's total water solutions segment generated billions in annual sales, with foodservice representing a material and consistently recurring revenue stream driven by replacement filter cycles. The engineering team remains anchored at the Illinois facility, maintaining the Micro-Pure technology roadmap and supporting OEM partnerships with major restaurant groups. The structural differentiator is Everpure's embedded-OEM posture. It does not sell water filters to consumers in retail aisles. Instead, the firm engineers its filtration systems into the equipment specifications of global franchise networks. Once a McDonald's or Starbucks location adopts Everpure as the specified filter, the replacement cycle is locked into the franchise's operating manual, creating high-switching-cost recurring revenue that mirrors the installed-base economics of an enterprise software company but with a physical consumable.
