Once you determine your size, we recommend purchasing at least 3 masks per person. One to wear, one that can be in process of washing and another as backup.
What are Enro masks made of?

Filter Layer: Melt Blown Polypropylene (MBPP)
Inner Layer: 100% cotton treated with SILVADUR™ antimicrobial finish
Ear Loop: 80% nylon, 20% spandex
Stopper: 100% TPE
Beads: 100% PP
Nose Bridge: 35% Iron + 65% PE
What are the perforations on Enro mask's outer layer?
The perforations on the exterior layer of the mask allow for improved breathability of the mask. It does not impact the protection provided by the mask or the filter. It also does not impact the water repellent finish on the out layer of the mask.
Why does the Enro mask not have a valve?
While valves do allow you to breath easier, they also do not have filters that stop your germs from infecting others. The CDC states the following: "Masks with exhalation valves or vents should NOT be worn to help prevent the person wearing the mask from spreading COVID-19 to others (source control)."
Is the Enro mask hypoallergenic?
Because there is no standard definition of "hypoallergenic" in the industry as of now, we can't claim Enro masks as hypoallergenic. That being said, we work very hard to use sustainable materials that are both safe for you and better for the environment. If you have a concern with allergies, please reference the components used in the production of the mask against known allergies. The Enro mask blocks 99% of pollen often helping people with allergies!
How do you adjust the mask to fit?
Once masks is positioned on your face, adjust the nose bridge to keep the mask firmly in place. Then adjust the ear loop stoppers for a secure fit.
How was the Enro mask tested?
Enro masks are tested using standards created by the American Society for Testing and Materials (ASTM) and the American Association of Textile Chemists and Colorists (AATCC). We leveraged best in class independent laboratories (TUV & SGS) to conduct the test. For more information or test results, please contact customer service.
Does the Enro mask block odors?
Enro masks do block some odors through the fabric layers and filter, but are not intended as an odor block. The SILVADUR™ antimicrobial finish helps to provide freshness protection and enhanced odor control from naturally occurring odors during wear.
Where are Enro masks made?
Enro masks are designed in the USA and Hong Kong. They are produced in a top of the line facility in Vietnam. The facility is Blue Sign certified and is FDA registered.
Care & Use
How often should I wash my Enro mask?
Just like your socks or underwear, you should clean your mask after each day of use.
Just throw your Enro mask in with your regular wash, no special wash cycle required.
Your Enro mask is machine washable and dry-able up to 100x.
Wash at 100° F/ 40° C and tumble dry low
We do not recommend cleaning with alcohol spray because it will wear down the anti-microbial finish more quickly.
Can you wash an Enro mask in a laundry bag?
Yes. While not required, it does reduces the ear loops from tangling and some wear on the mask.
Should the mask be used in a clinical setting?
No. We do not recommend using an Enro mask in a clinical setting where the infection risk level through inhalation exposure is high. Please use a certified surgical mask for these situations.
Can you use the mask in high risk aerosol generating procedures?
No. Enro masks are not certified to block high risk aerosol generating procedures. Please use proper filtering equipment made for those processes.
