I work in the Emergency Department. Needed something better than an N95 mask to protect from aerosolized coronavirus. This combines all of the best protection and it's really comfortable. The battery works an entire 9 hour shift on high power. I prefer the comfort accessory for the top of the head, but I have a coworker who doesn't. Your choice. Easy to clean. The belt is ridiculously long for bigger folks. The duffel bag works great too. Don't leave the battery charging longer than 80 hours. Pro tip. Expensive, but worth the investment. No clue how it works when welding. I've been using it for a few weeks, with daily exposure to coronavirus, and haven't gotten sick (knock on wood).
Long battery life
