I mainly use it as a bulb to clean my electric shaver. To generate more power I removed the filter and it works great. I'll be using it on the camera bodies, but that's where I'll put a filter canister and maybe use an extra inlet filter as well. Air force is not a necessity in this application. I used the vacuum part on the keyboard, but that's not the main reason for my purchase. Nice tool and I'm glad I have it.
