When you need to clean the filter (not the sensor !)...

Forget the bulb/blower -

If you think abut it for a minute or two...

The ILC/DSLR camera body is basically a big cavity, box, with nooks and crannies all over inside...right ?

So now, one takes this all fixing the dirt "blower" and you insert the nozzle "inside" this box full of nooks and crannies... You squeeze the bulb to force air out of it and into the camera (box, full of nooks and...), this pressurized air blasts the sensor "filter" (NOT the actual sensor !), and then what, does it magically disappear...no, it ricochets (bounces) off the filter surface...and THEN where, NO one knows, the apparently dirty air bounces all over inside of your expensive camera body, "AND", carries with it...the dirt you are trying to "remove"..!  How much "ACTUALLY" comes "out" of the camera..no one really knows.

So now what, that dirt is, for the most part, still inside your camera body, just not on the filter..."for now"..! It WILL find its way back to the sensor/filter in a matter of time. Could be, 5 minutes, could be three weeks, but it's still there waiting to migrate back to the filter.

Most anything but a blower..! I mostly use a statically charged brush to "collect" the dirt and deposit it...outside...of the camera.
