My prefilter has been in for 6 years, guess that's only $.33 a year. But its still $2 or more to replace it when and if it ever plugs. So I will still clean it and reuse (recycle) it. I don't subscribe to the throw away world if I don't have to.

Years ago, MB recommended cleaning the fuel filters and even made a tool to clean the cartridges in the old style fuel filters. I guess it wouldn't pay for most people to do that anymore at today's outrageous labor rates. But my labor is free, so it still pays me to clean my fuel filters and reuse them.

We have to update Ben Franklins statement of a "Penny saved is a Penny Earned" to "A Penny Saved is 2 Pennies Earned Before Taxes".
