Here is an inline filter that reduces sediment down to 5 microns. This filter is installed on 1/4" water lines. Each end of the filter requires a 1/4" x 1/4" Male Nylon Connection Fitting to install the filter on the water line.

The 1/4" fittings are listed below the filter. You will need 2 of them.
Thank you,
