Himalayan salt lamps designed to purify air and improve sleep quality are a scam, a Manhattan man claims in a new class-action lawsuit filed against a company that makes the trendy lights.

Daniel Okoe paid $25 on Amazon for his set of two Amethya brand lamps, according to the advertisement cited in Manhattan federal court papers.

The maker of the lamps is a Connecticut-based company called Headclicks Inc.

Okoe wants Headclicks Inc., to stop its “deceptive” advertising. The company did not respond to messages.
