Learn how the envo® mask achieves comfort and security.

NIOSH-approved materials and a unique design make envo® mask both safe and easy to wear.

What is an N95 respirator?

An N95 respirator is a type of personal protective equipment (PPE). N95 respirators are rigorously evaluated and approved by the National Institute for Occupational Safety and Health (NIOSH), a research institute within the Centers for Disease Control and Prevention (CDC). Workers can wear this type of respirator to mitigate the risk of airborne transmission of pathogens.

The N95 designation refers to filter performance, where “N” means non-oil proof and 95 represents the percent of particle collection at respirator certification test conditions.


What makes envo® mask effective?

Envo® mask provides a lightweight, low-resistance barrier against most airborne particles.


Four layers of synthetic plastic (polypropylene) fibers keep airborne and liquid particles out, while letting clean air in.

Low resistance

Non-woven fibers allow air to pass freely while trapping solid particles and non-oil based liquid droplets as small as 0.3 microns.

Close fit

A patented, latex-free AIRgel® seal conforms to the wearer’s face to prevent air leakage.

Electrostatic charge

Static electricity attracts and traps microscopic particles.

Ergonomic headgear

Two strap configurations provide ergonomic, adjustable options for all-day comfort.

One- or two-way port

The envo® mask respirator is available with or without an exhalation vent. The ventless option prevents the wearer from spreading potential pathogens via their exhalations.

Technical Reports

Envo® mask Passes the test

NIOSH approval for envo® mask is based on accredited tests.

I’m a respiratory therapist and I do N95 fit testing at a hospital. Every person has a different size and shape to their face. I’m confident in the mask’s fit and seal. It never fogs my glasses, even after hours [of use] I’m still comfortable. You get busy rushing in and out of the covid rooms, I don’t have to worry because I always have my mask on.
Respiratory Therapist
I’m an ICU nurse and have to wear an N95 everyday, having an envo has made this much more comfortable to do. Its gel padding doesn’t cut into my face like normal N95s and feels more breathable to wear for long periods of time.

The envo®mask with AIRgel has literally been a lifesaver to my everyday life, working in the hospital & outside life such as school.
