Feedback about: A face mask for people who have difficulty breathing


Have you looked at powered positive pressure options? There are several groups developing small powered blowers. A group I am part of is developing a [powered face shield]( that is designed to be work with a mask but its also compatible with other headpieces. There are several groups developing open source blower units at the moment. I think the cost is about $80-100 for most units but we expect to get it down to about $50.
