Review on 3M Personal Protective Equipment Versaflo by Bob Roberts

I bought this machine because I work in very dusty conditions. Such as: Residential Demolition, Woodworking, HVAC, Welding, Concrete Mixing, Mortar Mixing. I have terrible allergies and am constantly exposed to many small particles that are dangerous with long-term exposure. The device is just as easy to use and more comfortable than a traditional 3m full face respirator. I decided to upgrade because I generally sweat a lot at work and even more when I'm wearing a full face mask. This device, if you start it and then put it on according to the instructions, eliminates breathing difficulties, stuck one-way flaps and provides excellent airflow to the face. I'm 6ft 1in and the hose doesn't tighten when I bend over or squat. The battery will charge in about an hour. The filter is durable and relatively easy to change. My only recommendation is to get a hardhat liner and consider buying a backpack accessory so it doesn't crack regular plumbers. Otherwise, 3M did a great job developing this product.
