What are the three most common types of fuel filters?

• A. The micron filter, and the wafer screen filter.
• B. The micron filter, the plain screen mesh filter.
• C. The micron filter, the wafer screen filter, and the plain screen mesh filter.
• D. The wafer screen filter, and the plain screen mesh filter.

Answer: (C)

Fuel filtration in aircraft fuel systems relies on filtering at different grain sizes to protect pumps and injectors. The three most common types you’ll encounter are the micron filter, the wafer screen filter, and the plain screen mesh filter. The micron filter handles fine particle removal, catching very small contaminants to prevent injector or pump wear. The wafer screen filter is a compact, flat-screen style that intercepts mid-sized debris while preserving good flow. The plain screen mesh filter acts as a coarse screen to remove larger debris before fuel reaches the finer filters downstream. This combination covers a wide range of particle sizes, which is why these three are considered the standard set. If a option omits one of these types, it wouldn’t provide the full spectrum of protection.
