Difference Between a Filter and a Strainer

Industrial strainers and filters efficiently eliminate undesired particulates from both liquids and gases. 

The primary difference between strainers and filters are the particle sizes they remove.

Strainers remove visible and larger particles from liquids or gases, while filters remove tiny contaminants invisible to the naked eye.

The table below provides a brief description of the primary difference between filters and strainers:

Difference	Strainer	Filter
functionality	The strainer traps debris, enabling the valuable liquid to flow efficiently through the system	The filter captures the valuable substance while allowing waste to pass through the system
re-usage	The strainer can be cleaned and reused	You can continue to use a filter until it becomes clogged, at that time you must change it
type of operation	The strainer is referred to as a coarse operation.	The filter is referred to as a fine filtration.
basic usage	The strainer is used to capture large chunks of the valve industry	The filter is used to remove particles or small microbes
pressure drop	The liquid or gas passing through the strainer will not undergo pressure drop	When liquids or gases pass through a filter, they experience a certain pressure drop.
Particles size	The strainers are used to remove particles larger than 40 microns	The filter are used to remove particles smaller than 40 microns
quick cleaning	Quick cleaning strainers need less downtime	Quick cleaning filters are impossible because they would spend a significant amount of time
