Razer has not yet responded to PCMag's request for comment from last week. Note that on its page, Razer does not say the masks are 'certified,' only that they 'took guidance' from regulators. On Saturday, it simply posted a tweet that said it has 'taken feedback and guidance from regulatory agencies to establish our testing protocols for the Razer Zephyr and Razer Zephyr Pro,' which includes a link to the aftermentioned science website. The company did not publicly announce the removal of 'N95 grade' from its website. 'The Razer Zephyr and Zephyr Pro are not certified N95 masks, medical devices, respirators, surgical masks, or personal protective equipment (PPE) and are not meant to be used in medical or clinical settings.' 'Razer Zephyr is not a medical device, respirator, surgical mask or personal protective equipment (PPE) and is not meant to be used medical or clinical settings.' UPDATE: Over the weekend, Razer removed references to 'N95 grade' from its marketing web pages, and updated the fine print on its 'The Science Behind Razer Zephyr' website (Opens in a new window). UPDATE 2: In a statement, Razer confirms that 'to avoid any confusion, we are in the process of removing all references to 'N95 Grade Filter' from our marketing material.' It also pledged to reach out to existing customers to 'clarify' what the mask can and can't do.
