all applications are created equal; however, the goal of all filters is:
Keep the dirt out! The most common type of filter is a barrier type, which
typically is just an element with a pre-filter that sits in some type of a
holding frame. They come in
various styles and configurations relative to the media and replacement
schemes. In addition, they tend to be less money per CFM and thus more
is no such thing as a filter that gets out everything, though.
That is why LoTec suggests a wash system.
However, wash systems are not a substitution for filtration.
