Use your blower to dry K&N AIR FILTERS

Here's another use for your blower.  K&N makes air filters which you can wash and re-use; but you cannot use compressed air to dry them because you risk blowing out the cotton fibers between the fine mesh screen.  So rather than waiting several hours, I fired up the trust ego blower at low speed, and then after putting the filter in front if it (blowing air into the filter), I hit the turn button to raise the air pressure.  I found that holding the filter 1" from the nozzle was better than pressing it completely against it so that there wasn't excessive back pressure in the blower.  Dried each one for about five minutes, and the 5.0 AH battery had plenty of juice left over (put it back on the charger and it was reading 3 bars off the bat.

Forcing unfiltered air into the 'clean' side of the filter seems to be a terrible idea. over time the particulates will work free from the inside of the filter and work their way into your engine.

Whether or not this matters is another question as K&N filters themselves aren't the best cleaners.

Unless you're drying the filters on a windy day with lots of hard sand type debris flying around, I doubt there's much to be worried about.

Agreed that K+N filters are not very good at filtering small debris, but that's another topic altogether. ;-)
