The lawsuit against Philips Respironics defendants was consolidated into a multi-district litigation (MDL 3014), which then spawned related satellite lawsuits against SoClean, Inc, a company that makes a product specifically used to sanitize CPAP devices.

An MDL (MDL 3021) was then created for the lawsuits filed against SoClean, alleging that the company falsely marketed their product as "safe" and "healthy" for sanitizing CPAP machines and other breathing devices. SoClean's product was unsafe because it emitted harmful levels of ozone gas, which exceeded the maximum safe limits set by the FDA.

After the settlement was reached between Plaintiffs and Philips Respironics Defendants on April 28, 2024, Philips Respironics filed a lawsuit against SoClean, seeking contribution to the $1.1 billion settlement. The lawsuit alleges that many of Plaintiffs' injuries were caused by excessive ozone released by SoClean's cleaning systems, and also targets DWHP, an investor in SoClean.
