This can vary widely depending on how often your dust collector is used, and what kind of dusts it's exposed to. You should typically clean it only once you've noticed a considerable drop in suction performance. In our experience this can be around 1x per year, but with heavy amounts of sanding it could be as often as 1x per month. A pressure meter such as our Filter Efficiency Gauge can also be used to monitor pressure buildup.
