Action Against Sub-Zero Dismissed, Renewing Focus on Ventilation and Consumer Choice

A federal lawsuit alleging health risks associated with gas appliances has been dismissed, reaffirming the importance of informed consumer choice and proper home ventilation.

Filed in Wisconsin, the class action targeted premium appliance brands Sub-Zero and Wolf Appliance Inc., accusing them of failing to warn consumers about potential emissions from gas cooktops, stoves, and ovens. The case was dismissed *with prejudice*, meaning it cannot be refiled, and no changes were made to product labels or warnings.

Sub-Zero and Wolf have long been trusted by professional chefs and home cooks alike for delivering powerful, responsive heat — a key advantage of gas cooking. Their appliances are designed to meet high performance standards and function safely when installed with adequate ventilation, as recommended across the industry.

While the lawsuit is no longer active, the topic of indoor air quality continues to spark conversations. Similar cases have surfaced against other manufacturers, pointing to a growing interest in household environmental awareness. But experts agree: when used correctly and maintained properly, gas hobs remain a reliable and effective tool in kitchens worldwide.

Sub-zero investment

Sub-Zero Group intends to invest more than $140 million to build a 400,000-square-foot plant in Cedar Rapids. The factory would create 192 jobs; 127 of those positions would be paid at or above the qualifying wage of $24.20 per hour.

Sub-Zero, based in Madison, Wisconsin, makes its flagship brand of refrigeration products as well as Wolf cooking appliances and Cove dishwashers. The Cedar Rapids plant would bolster the company’s overall manufacturing capacity; it currently operates factories in Fitchburg, Wisconsin, and Goodyear, Arizona.

State officials approved an incentive package worth $3.7 million to support the project

The Iowa Economic Development Authority also on Friday awarded $2.56 million in investment tax credits and sales and use tax credits to Sub-Zero, a Wisconsin-based refrigeration and appliance manufacturer, to build a 400,000 square-foot facility east of Cedar Rapids’ Eastern Iowa Airport.
