Primo Water: Filtered Water Dispensers and Self-Service Refill Stations

Primo Water Corporation (Tampa, Florida) operates the largest self-service water refill station network in North America (over 13,000 Primo Water Exchange and Primo Water Refill stations at Walmart, Home Depot, Kroger, and other retailers) and sells Primo-branded water dispensers. In the water filter context, Primo's water is purified through reverse osmosis at its exchange/refill stations before being bottled or dispensed, providing access to RO-purified water without a home filter system. Primo dispensers (bottom-load and top-load) are the delivery mechanism, not the filter themselves.

Primo Water Exchange vs. Home RO: Cost Comparison

OptionCost per GallonAnnual Cost (4 gal/day)Upfront Cost
Primo Water Exchange (3-gal bottles)$1.00--$1.50$1,460--$2,190$0 (cooler $50--$150)
Primo Water Refill (self-refill)$0.25--$0.40$365--$584$0 (own container)
Home RO (APEC ROES-50)$0.04--$0.06$58--$87$200--$260

When Primo Makes Sense vs. Home RO

Primo Water Exchange or Refill is the right choice for: renters who cannot install an under-sink filter; households in apartments with lease restrictions; temporary or transitional housing; emergency situations where the home water supply is compromised. For permanent homeowners, a home RO system recovers its cost in savings from Primo exchange water in 2--4 months -- the economic case for home RO vs. Primo exchange water is overwhelming for any household that will use the home for 12+ months.
