Are there specs on how many microns this filter is rated at? Is there available another filter that won't allow finer particles to pass through?

A  Answered on 10/1/2014 by InyoPools Product Specialist Patrick P.

As a rule, sand filters sift particles ranging from 20 to 40 microns in size.  Cartridge filters can sift particles as small as 10 to 20 microns in size.  DE filters can sift contaminants as small as 1 to 3 microns in size. This makes DE filtration at least five to six times more efficient than sand filtration systems.
