[b]The old days are gone. My old furnace used old, simple, cheap filters. But now I've got a new Trane S9X2 furnace. It calls for “high velocity” filters without defining that term or offering specific filter suggestions. From searching around, from what I gather, I should get a pleated filter to increase the amount of filter “space” and increase the volume. What I also want is a permanent, washable filter, and from what I understand, I should get an Electrostatic Filter. Using these criteria, there are still lots available to choose from with prices and attributes all over the place. So I have two questions: 1. Is my understanding of my filter needs correct? 2. Any particular things to look for or avoid in my selection? I'd rather not spend $100 for a filter only to find that it's not the best for my furnace, or that I paid way too much. Any ideas, thoughts suggestions will be appreciated.[/b]
