SEBO Filter Indicator for 3...

Product details
Filters get serviced when the machine asks for it, not when the calendar says so. Part 50209ER is the filter indicator that does the asking on the SEBO 300 Mechanical and the SEBO 350 Mechanical, flagging the point at which the filtration needs attention.
Dust working in behind the lens, a slide that has seized, or a faded display all leave the indicator stuck on one reading, and once it stops moving the machine has lost the only prompt that keeps its filters current. Suction then drifts down slowly enough that nobody notices until it is already bad. A live indicator also settles the most common diagnostic argument on an upright, because it separates a loaded filter from a blocked hose the moment pull drops off. If the reading has not shifted through a full box of bags, treat the indicator itself as the suspect rather than the filtration.
Once the machine is telling the truth again, the consumables it points at are straightforward. Microfilter 5036AM is the standard media for these uprights, 5812ER is the HEPA version and 5425AM the anti-odor version; exhaust inserts are 50169ER in HEPA and 50170ER in S-class, held in place by orange box 50216OR. Bags come in the eight-bag box 5093AM, and the cover the filtration sits behind is held shut by safety catch 50205ER.
