That is the expected results when good filters are used. In addition,the air is healther,house dusting is less,and there is energy savings. Just for the record,$8 or $10 filters do about as well except taking pollen and mold spores out of the air which in itself is worth $20 to people with sensitive respatory systems( probibly more than 50% of us over 60.) In addition to using a good filter you can hedge the benifits even farthur. When replacing the air handler insist on a 25x25 or 20x25 filter holder. Simple math tells us the 20x25 has over twice the suface of 12x20 or 16x14 which translates to lasts twice as long. I fabricated holders that hold 2 20x25 filters 3" apart when installing my units. I use a $4 paper pleat in first one air passes through and $15 pleated high effeciency downstream. I get 3 months out of the $4 one and 6 months easy from the $15 filter because it has no dust or lint on it,only black stuff I assume I would rather not breath. To judge when a pleated filter is due,non too soon nor too late,hold it up to weak light. After several days you will note only about 25% of deepest part of crease restricts light while the other 75% of high points are clean as new. As time passes,the coverage creeps toward the peaks of pleats. Just as light is passing unrestricted 1/8th inch on each side of peak is time to change.

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
