Buy a fume extractor from a reputable manufacturer who specializes in low maintenance laser fume extractors. They are designed in such a way that you only need to change the filters as soon as the alarms tell you to, and you will maximize the life of both the filters and your extractor. Most systems use brushless blowers that don’t need any maintenance, but if you are on a budget and are considering an extractor with brushed blower, make sure that the replacement process is quick and easy as the blowers need servicing every 600 to 2,000 hours, depending on the manufacturer.
