Various outlets, including Engadget and The Verge, note that the company has erased every mention of “N95-grade filters” from the product pages for both the $100 Zephyr and recently announced Zephyr Pro masks.

Wu’s detailed breakdown of how ineffective the Zephyr mask is at protecting you from covid-19, its myriad variants, and various other diseases is eye-opening.

For its part, Razer has opted to update its marketing materials for the Zephyr while scrubbing the phrase “N95-grade filters” from the website’s product page.
