Ants Duraprot Mask

**UPDATE:We have stopped valved versions as per government directive.

antsLAB Duraprot Self-Sanitising MASK is offered in valved and non-valved exhalation respirator configuration.

The exhalation valves are designed to make it easier to breathe out, because these one-way valves release exhaled air without forcing it through a filter. The mask still protects the wearer from breathing things in, but it does very little to prevent an infected person from spreading infectious droplets when they breathe out.

VALVED antsLAB Duraprot Self-Sanitising MASKS help protect the mask wearer from inhalation of viruses and microscopic particles and feature 1 or 2 exhalation valves. Please note that the exhale of the mask wearer exits partially through the valve unfiltered.

NON-VALVED antsLAB Duraprot Self-Sanitising MASKS help protect both the mask wearer from inhaling viruses and microscopic particles AND help protect the environment from the exhaled droplets of the mask wearer.

Note that NON-VALVED antsLAB Duraprot Self-Sanitising MASKS filter both inflow and outflow.
