Hi Brian, it all boils down to the level of protection that you want. The dust be gone filter is less efficient but it's more comfortable and easier to use. My strategy is actually use both of them. I plan to use the Totobobo for when I empty my dust collector or have high dust in the air. When I'm simply scrolling I like to use the dust be gone. If I could only have one I guess I would go with the Dust be gone.
