My DNA filter is not a foam filter. It�s fiber. And the process of servicing it according to the instructions in the DNA service kit is quite specific and easy. Spray on filter lube might work but the DNA lube is very thin and flows into the fiber when applied on the outside ridges of the filter folds coloring it pinkish so one can see when it�s saturated just enough.
