Micronic-type filters can use which materials?

• A. Paper only
• B. Paper or metal
• C. Metal only
• D. Ceramic

Answer: (B)

Micronic-type filters are designed for very fine particle removal, so the filter media must be able to create stable, tightly controlled pore sizes while withstanding the system’s fluids. The two most common media for this kind of filter are paper and metal. Paper filters use cellulose to form a porous path that traps small particles and is inexpensive and lightweight, making them suitable for many applications, though they may have limits in chemical compatibility and temperature. Metal filters, typically sintered or mesh-based, offer greater strength, higher chemical and heat tolerance, and the ability to be cleaned and reused. Ceramic media do exist for certain high-temperature or specialized filtration needs, but they are not the standard media for typical micronic-type filters in this context. Hence, micronic-type filters are commonly made from either paper or metal.
