With a dual racor setup, how do you all cycle the filters? Do you use one filter and then when time to replace that one you switch over to the other (replace the used one and keep it installed but inactive)? Or do you replace both even though one hasn't been used? Or use both and replace both when the time comes? I use one at a time so I always have a clean filter installed and ready to go if I get contamination.
