On some gravity feeds inline with whatever ... I am thinking that a 90 micron filter element might restrict liquid flow a lot less than an inline 5 or 1 micron filter element ... not sure though. Possibly something to consider in some situations.The smaller the better, 5 micron should be more than fine enough and will last longer than a 1. I get a lot of really fine silt in the holding tank for the high pressure pumps, so I'd probably use a 1.
