Image sensor cleaning risk using blower bulb

How much risk is there in using a blower bulb (a VisibleDust Hurricane Blower) to clean the image sensor (the low-pass filter or SP coating)? Is it effective? Is there a risk of introducing more dust?

As long as the camera does not shut off and flip the mirror down or you do not touch the sensor, there is next to zero risk. Someone however reported a small bug (insect) had blasted out of his blower (think splatter on the windshield) and created a big problem. So give the blower a few blasts before aiming it inside your camera.

Somehow a fiber had gotten onto my sensor. No idea how, but I followed the instructions here https://www.pentaxforums.com/forums/pentax-dslr-discussion/120365-dusty-sensor.html

and got one of these
Amazon.com: Giottos AA1900 Rocket Air Blaster Large (Black): Camera & Photo

and all is well again.

I'll probably get the Giottos AA1900. It seems more people use this and that this is a better solution.

I have a generic blower and use it pretty often. I have sometimes noticed more dust specs after I use it but those specs could have already been in the camera and the blower made them visible, but I just do the blower again and their gone. I think most blowers are very safe to use, but I would give it a few squeezes before you actually blow inside your camera.

If you want to be extra safe, you can try to blow out any contaminants from the blower before pointing it at the sensor, and also not insert the nozzle so far that the mirror would hit it if it went down unexpectedly.
