Background
Plaintiff Nicholas Brown filed a putative class action against The Brita Products Company alleging violations of the California Unfair Competition Law, False Advertising Law, and Consumer Legal Remedies Act. Brown claimed that Brita’s water filters did not reduce hazardous contaminants to below lab detectable limits, despite packaging representations that they reduced contaminants. He argued that Brita failed to disclose these limitations, constituting a material omission.
The court’s reasoning
The panel concluded that a reasonable consumer would not expect Brita’s low-cost filters to completely remove or reduce all hazardous contaminants to below lab detectable limits. The court noted that Brita’s packaging clearly stated the products ‘reduce’ contaminants and provided Performance Data Sheets detailing specific reductions. Because the complaint failed to meet the reasonable consumer standard, the district court did not err in dismissing the material omission claim. The court also affirmed the denial of leave to amend, finding that no amendment could cure the fundamental flaw that reasonable consumers are not misled by the product’s limitations.
We conclude that reasonable consumers would not have that expectation.
Brown v. The Brita Products Co., 24-6678 (9th Cir. 2026)
What it means going forward
The ruling reinforces that consumer protection claims based on omissions must satisfy the reasonable consumer standard, requiring a probability that a significant portion of the public would be misled. It clarifies that clear disclosures and the objective unreasonableness of certain consumer expectations can defeat claims even if a product does not perform to a plaintiff’s subjective hopes.
