Razer sold its Zephyr face mask as "N95 certified," but failed qualification tests and now must reimburse consumers.

N95 masks are generally the most effective protection against airborne particles (and ideal for healthcare and industrial workers), but they are uncomfortable and require a tight fit.

A PLOS ONE study tested the real-world filtration efficiency of cloth masks, medical masks, and respirators, revealing large differences in performance based on fit and mask type. Only N95s and ...

I bought it to GET MY KIDS OUT OF THE HOUSE TO SCHOOL ON TIME. They consistently won't be ready every morning without me hollering, '10 minutes! 5 minutes!' If I missed these callouts, no one was ...

The best mask for kids is the most protective one they’ll keep on. We have four to recommend that are high-performing and breathable, and fit a range of ages.

Professor recommends 'gold standard' face mask that offers 'best' protection against Covid A public health expert has recommended wearing a face covering as Covid cases continue to surge as new ...

A research team at the University of Liverpool has developed a new material that captures coronavirus particles and could transform the efficiency of face masks and other filter equipment to stop ...

The US National Renewable Energy Laboratory (NREL) has released a new, interactive version of its research cell efficiency chart for a range of PV technologies.

According to the authors, even the efficiency of N95 respirators might be 50% decreased. They also demonstrated that double masking might not increase the outer protection of masks much.
