envo​®​ mask

envo​®​ mask is intended to have a comfortable seal to minimize skin irritation, using vapor barriers around the nose to prevent the mask from fogging glasses. The electrostatic charged filters should allow long term storage, and be safe from damage produced by the constant action of taking the mask on and off. The one-way exhalation valve reduces temperature and moisture inside the mask. The mask chamber’s design and filter placement improve speech clarity. Headgear is designed to be easily taken on and off and allows the user to remove the mask without touching the mask or damaging filters. The product includes a storage case with replacement filters to protect the mask.

Technical support provided by the manufacturer.

It is recommended to discard the filters after every use, as they are not suitable for multi-day activities. The mask’s lifecycle depends on the usage, as it can be washed and reassembled multiple times. envo​®​ mask offers a 90-day warranty against manufacturing defects.

Product was approved by NIOSH in 2019, which implies that its inhalation and exhalation resistance has been evaluated in a laboratory, and it has been found to comply with all of the requirements of Title 42 CFR Part 84 for respiratory protective devices. Filters and valves were also tested by a laboratory to evaluate filtration efficacy and valve leakage respectively.

As the mask is reusable, it can be hand washed with mild soap, warm water, and a soft cloth to remove dirt and dust. Filters should be discarded after every use.
