Two types of internal disposable N95 and N99 filters are available with the IMask+, making the IMask+ a most versatile protective health mask suitable for all varieties of usage.
The filter shown in the images above is solid and is suitable for most conditions and situations, including protecting the user and anyone around the user from airborne pathogens, such as influenza and the COVID-19 pandemic. It also protects the user from airborne contaminants and particulates associate with smog, industrial waste, construction sites, factories, disaster areas, and fires. This filter protects both the user and people around the user, and so is the choice in a pandemic.
The filter shown in the images above has a central opening which fits around the one-way, and is suitable for airborne contaminants and particulates associated with smog, factory waste, construction sites, disaster areas, and fires. This filter protects the user, but does not provide protection for the people around the user, as is so important in the face of a pandemic.
