FTC sued Razer, a gaming and lifestyle company, after the company sold the Zephyr mask as an N95-equivalent mask. N95 masks are designed to have a tight fit to the user's face and efficient filtration of airborne particles. Since it is a government-regulated standard, a company can't release a mask and label it N95. It must be certified first.

After announcing a settlement last year, the FTC is now sending refund checks to 6,700+ consumers who bought Razer's air-filtering mask, which was flagged for deceptive marketing.
