I have a Rheem Classic 90 furnace that was installed several years ago. It came stock with a re-usable plastic fine mesh filter that I remove and clean every few months. It seems to me that a paper HEPA type filter would do a much better job of filtering the air. The stock plastic mesh filter seems like its too much of an open weave to be really effective with dust and other allergens (we have pets). My question is: Can I replace the stock plastic mesh filter with a pleated paper type filter and not severely effect the airflow or performance of the furnace? What thickness filter would be an appropriate replacement?

Power windows quit working ...then start again..... check battery light did come on for a few minutes, and then went out, and the ABS light came on for a couple of minutes and then went out ( not all at the same time ). This car has done this every couple of weeks. The battery is good (1 yr old ), and the serpentine belt is brand new. I'm scratching my head on this one... any GM Techs out there who have run across this problem before?

1974 Chev 350, standard points ignition. Heads, intake, and carb replaced recently. Old heads were 1.94 intakes & 76cc chambers. New heads 2.02 with 64cc chambers. Old Comp. ratio --8.5 to 1 Now 9.5 to 1. Stock cam retained. Valves are adjusted properly, motor is timed @ 8*BTDC, dwell@ 29*. Carb is adjusted correctly. No vacuum leaks. Car misses at light throttle coasting down the street at about 30mph. Also misses at higher speeds. It's not a dead miss from one cylinder. What am I overlooking???
