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.

Up to what size pool is this filter good for; in other words how many gallons of water in the pool.

A  Answered on 2/13/2015 by InyoPools Product Specialist Robert M.

Hello Tony - In a perfect world this filter can handle 43,000 gallons. In reality, we would not recommend this filter for anything more than 20,000 gallons.
