In the Navy (not the Village People song) we would coat all the foam and fiberglass filters with "filter coat" to increase the static attraction and collect more of the finer stuff. Part of our mandatory preventive maintenance routine. Those subs would produce a couple of trash bags of lint/funk daily and all the equipment had high rpm intake fans to cool the relays and other components. It wasn't an option to use it or not. If it's on the preventive maintenance schedule you did it or else.
I personally have been spraying lysol on my cheap fiberglass filters at the apartment complex to help deodorize and sanitze the extreme funk that goes on there. It also leaves behind a tacky surface on the filter that I'm hoping will attract more pet dander, fine Georgia dust and whatnot. Don't beat me up about proper cleaning, coil pulls, duct cleaning, proper filters and 4-5" media.... The apartment complex aint goin' for none of that. So, in your wise and varied opinions, do you think spraying the filter with a hefty coating of lysol at every filter change will cause more problems than it's worth?
It seems like a good idea, but so did the nuclear bomb! Just want to make sure I'm not unintentionally creating job security for myself by ruining a bunch of coils. All are split system R22 heat pumps at least 12 years old.
