Ultra-low frequency ultrasonic cleaning machines have been linked to the deaths of at least 10 people in California and Michigan.
The ultrasonic cleaner is manufactured by Ammonia Cleaning Systems, which was founded by two ultrasonic-tongued ultrasonic tech-savvy executives in 2015, according to Reuters.
In February, the company announced plans to buy out rival CleanTech, a technology company that was founded in 2009 by three ultrasonic cleaners who were also ultrasonic.
According to Reuters, Ammona Cleaning systems has more than 200 employees in Los Angeles and New York, including one in California.
According the company’s website, the products include:• An ultrasonic soap soap for children• An ultra-low-frequency ultrasonic tool for cleaning hard surfaces and fabrics• An ammonia cleaning product for removing ammonia from air and waterThe company was also acquired by CleanTech last year, according the report.
The two companies have been accused of misusing patents and patent infringement allegations, which are in addition to lawsuits against Ammonacom and CleanTech.
Ammonia cleaning products have been used in more than 120 countries, according CleanTech’s website.
CleanTech and Ammoniacom both denied the allegations.
Clean Tech founder Mike Sibler said in a statement to Reuters that his company has “no relationship” with Ammonias product.
Siblers lawyer, John T. Kline, told Reuters that the allegations are “completely baseless.”
In March, the U.S. Department of Justice filed a civil antitrust lawsuit against Ammena Clean Tech and Clean Tech.
The DOJ alleged that the companies engaged in patent infringement and patent-infringement activity by marketing their products as a way to help children in developing countries.
Ammena has filed a countersuit against the DOJ.
The Department of Health and Human Services, the Consumer Product Safety Commission, and the Consumer Technology Association have all opened investigations into the alleged allegations.
The lawsuit is pending.
