Optimize Your Gard'n Gro and Green Knight with the Rainshow'r Prefiltration Filter
This unique, custom prefilter was designed by Rainshow'r to prevent sediment from reaching the Gard'n Gro and Green Knight garden filters. This is an industrial quality prefilter modified for garden use and is 100% made in the U.S.A. It features a 15 micron, double screen that can filter out sediment up to 5 times smaller than a human hair! Use of this prefilter drastically reduces the amount of sediment that reaches the KDF media in the Gard'n GRO and Green Knight garden filters, thus optimizing its electro-chemical action and effectiveness over a longer period of time.
