We collaborated with teams of mask experts, health professionals, and engineers to place humans at the forefront of our wearable air-purification technology. During the design process we engaged governmental agencies from around the world to understand their complex and evolving standards while increasing awareness in our efforts. Throughout our journey, we produced multiple design iterations and countless prototypes. At every stage, we integrated community feedback to help shape the Razer Zephyr family of products into something special.

Please observe your local safety regulations and mask guidelines or consult your local public health authorities for potential usability of these products under applicable law. 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. These products are intended to be used only with Razer Zephyr Filters.

Air Purification Filters

Air Purification Filters

Air purification filters are inside each of the two intake chambers and one more in the exhalation chamber. This safeguards you as well as others around you. We use polypropylene material for these filters - the same type used in other air purification masks.


We took guidance from regulatory agencies to establish our testing protocols. Each set of filters has been confirmed by third-party lab testing to meet a 95% Particulate Filtration Efficiency (PFE) and 99% Bacterial Filtration Efficiency (BFE) for up to 72 hours in a normal environment. The soft silicon face seal is designed to fit snugly over your mouth and nose and is made of the same material used in hospital-grade respirators for added comfort. Coupled with adjustable dual head straps, it has been tested to prevent air leakage during normal usage. The Razer Zephyr’s filters and airtight seal offer greater protection over standard cloth masks and daily disposable masks.
