Attorney General Chris Koster said he has filed suit against a St. Louis business and its owner for numerous violations of Missouri’s no-call law.

Koster filed the lawsuit against Pure Air Inc., doing business as Air Duct Cleaning, and its president, Noach Palatnik. Koster said the attorney general’s office has received more than 1,000 complaints about unwanted calls from Pure Air since March.

The lawsuit alleges that Pure Air used automated “robo-calls” to make thousands of calls to residents in the St. Louis area. Many consumers asked the company to stop calling them, only to receive dozens more robo-calls. In at least one instance, a company representative told a consumer that it was not subject to Missouri’s no-call law.

Koster is asking the court to stop the company from making any calls to Missourians on the no-call list and for penalties of $5,000 for each violation that occurred, in addition to paying for the costs of the investigation and prosecution of the case.

Koster reminds Missourians they can sign up for the no-call list on his website at or by calling 866-662-2551. He encourages consumers who receive harassing solicitation calls to file a complaint at 866-buzzoff (866-289-9633). Missourians can register their land and cellphone numbers with Missouri’s no-call list.
