Envo mask is a reusable N95 respirator (elastomeric respirator) that features a soft gel face seal. The envo mask is a NIOSH certified N95 respirator.
Unlike most reusable respirators, it's relatively easy to hear someone talking that's wearing the Envo mask. The Envo mask has an exhalation valve. The company ships each mask with a valve plug which can be used to seal the exhalation valve. A filter cover that lacks an exhalation valve is available as an optional accessory.
The Envo mask is made by Sleepnet Corporation, a company that had been manufacturing masks for sleep apnea. The envo mask received its first NIOSH certification in September of 2019. According to a news article, founder Tom Moulton got the idea to create the Envo mask after working a demolition project and becoming frustrated with the poor quality of most disposable masks:
“There’s got to be a better way,” Moulton thought to himself. He started working with his Sleepnet engineers to create what he thought might be a construction-type mask using his AIRgel.. -Interview with Sleepnet founder
