I'll probably weigh the new filter when I replace this one to get the tare weight and then just keep track of the gain over time/miles.
In the past, I just looked at the filter to judge the need for replacement. But, I like adding this additional metric. The two together should prove to be more reliable than just the eye-ball method.
