Who Owns ZeroWater?

Zero Technologies founded the ZeroWater brand in 2002, launching as a direct-to-consumer business selling filtration systems through its own website. The founding insight was measurable performance: a consumer filter that could take tap water down to a zero reading on a digital total dissolved solids meter, with the meter included so the claim could be proven at the kitchen counter.

The five-stage system combined activated carbon and ion exchange resin with multi-layer filtration media, removing dissolved solids that standard carbon-only pitcher filters largely leave behind. Early sales ran through the company's own channels before the brand expanded into national retail.

The 2007 NutriSystem minority investment and co-marketing deal supplied capital and distribution during the growth phase, placing ZeroWater products in front of NutriSystem's customer base.

Through the 2010s, the brand rolled into mass retail: Walmart, Target, Home Depot, and Amazon placed the pitchers and dispensers, while the replacement filter business grew as the installed base repurchased consumables on a regular cycle. The product line expanded from pitchers to larger dispensers, travel bottles, and multi-packs.

In independent testing, ZeroWater has consistently ranked at or near the top of pitcher filtration comparisons, typically scoring highest on dissolved-solid and contaminant removal among mass-market options through 2026 reviews from Wirecutter, TechGearLab, and Consumer Reports.
