How To Clean Furnace Filter
QUESTION:How do you clean an electronic furnace filter?
The furnace is making a constant crackling sound when it runs. On the electronic furnace filter box it says it will arc occasionally but if it arcs continuously then the filter needs cleaning. My dad used to clean it by soaking it in something but he has passed away so now I don't know what to do about it or what chemical if any to use.
ANSWER: I have no idea what he "soaked it in" it shouldn't need "soaking" only a wipe with a soft wet cloth like a terry cloth . The arc you hear is an electric arc from static electricity shorting through the filter. Make sure up turn anything off first, then try wiping. If this doesn't work, call the company that makes it. There should be a name somewhere on it.
This is a type of 'Osmosis system" which is an static electric system. Easy wiping is what they're noted for.
