When to replace a reusable air filter in a superduty truck?
I've had mine for 8 1/2 years. At what point do you replace it? It just feels like I need to clean it more often, like it's not performing like it did in the beginning.

Re-useable filters have charted performance values that are no longer valid after the first day of its installed life. It can never be cleaned to obtain the same performance as when new, one of the many factoids these manufacturers will not tell you. Often, it needs to be cleaned when the oem counterpart would be at only 10% of its useful life. There is PLENTY of factual data to back up all the "forum" anecdotal chatter. Time to unsubscribe to this, yet another pissing match around one of the biggest DIY cons in placebo psychology.
