After cleaning up the swamp cooler, lubricating, changing pads, removing last year's calcium, etc. for a new season how do you clean the dust and dirt out of the blower that shows up when the cooler is started up the first several times? I use an old A/C filter I hold against the inside-the- house grill to collect most of the dirt. The front grill doesn't come off, that I can figure out, to allow vacuuming it inside. I'm not sure where the dirt comes from - the new pads or it collects during the winter.
How do you handle this annoyance?
Also softening hard well water. I usually use one of those white blocks in the water pan. This year I may try an in-line water filter/softener. Ever try one of these?
TIA
