Which one of the following is not a type of a viscous filter?
Show Hint
Viscous filters trap dust with sticky oil — they’re cleaned, not thrown away!
Updated On: Jul 3, 2025
- Dry type
- Automatic type
- Replaceable type
- Manually cleaned type

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Viscous filters are air filters that use a sticky coating to trap dust and particles from the air.
They are typically cleaned and reused rather than replaced entirely.
They can be dry type (without oil coating) or automatic type (self-cleaning).
They can also be manually cleaned by washing or replacing the sticky media.
However, they are not normally fully replaceable type like disposable filters that are thrown away after use.
Therefore, 'replaceable type' does not match the design of a true viscous filter.
