Door-to-Door Water Filter Sale Leads To Refund in National City

A National City woman is sharing her story after a nearly $4,000 door-to-door water filter purchase led to a dispute — and a refund — with help from NBC 7 and Telemundo 20 Responds. Olegaria Herrera said a salesperson knocked on her door and described a water filtration system that immediately caught her interest.

“Truth is, I never saw the product,” Herrera said in Spanish. “He described it and how it would work, and it interested me.”
