Central Texas
We'll blow ours out when the indicator says it's time. If we replaced our outer filter every time it got dirty we'd really get rich off our wheat crop from this year. Maybe conditions are different in other places, but if we get a rain on our corn after it's mature I guarantee we'll be changing filters almost every day. We keep a couple spares and rotate them during the season.
