Which statement about the three-stage filter process describes the correct sequence of stages from first to last?

Which statement about the three-stage filter process describes the correct sequence of stages from first to last?

• A. NO GO FUSE: RAPID -> NO GO FUSE: ABSORBENT/ SLOW ACTING -> PREFERRED TYPE
• B. NO GO FUSE: RAPID -> PREFERRED TYPE -> NO GO FUSE: ABSORBENT/ SLOW ACTING
• C. PREFERRED TYPE -> NO GO FUSE: RAPID -> NO GO FUSE: ABSORBENT/ SLOW ACTING
• D. NO GO FUSE: RAPID -> NO GO FUSE: ABSORBENT/ SLOW ACTING -> PREFERRED TYPE

Answer: (A)

In filtration, you want to move from coarse to fine so the system works efficiently and the final polishing stage stays effective longer. The rapid stage removes the large particles quickly, which reduces clogging and keeps the flow workable for the next media. Then the absorbent, slow-acting stage spends more time with the fluid to grab finer or dissolved contaminants that the rapid stage can’t catch. Finally, the preferred-type filter provides the highest level of purification as the last polishing step, ensuring the fluid meets the required cleanliness with the media that delivers the best overall performance. Swapping the order would overload the finer or polishing media too soon or waste the capacity of the slow-acting absorbent, leading to faster fouling and poorer overall filtration.
