This bundle includes the time-tested filters we ship with our filter panels and housings, including the 20 and 5 micron pleated filters. Trust that your filters will operate as well as they did on day one by sticking with OEM replacements. We recommend changing your sediment filters every 6 months for average use cases, or when the PSI drop meets or exceeds 7 PSI.

All RainFlo Preferred Big Blue sediment filters feature integrated Buna-N gaskets to prevent contamination of filtered water, and the ends are completely molded into a vinyl plastisol base. The overlap seam is sonically welded to reduce internal bypass improving filtration efficiency.

RainFlo Preferred Pleated Filters
RainFlo Preferred Filter



The RainFlo Preferred 20" x 4.5" Full Flow/Big Blue pleated filters have more than 16 square feet of filtration surface area. The media is pleated to maximize dirt-holding capacity and extend the time period between changes or cleaning. The Premium pleated cellulose cartridges are manufactured from a durable, bacterial resistant, non-woven polyester cellulose that is suitable for a wide range of filtration uses. The filter media is pleated around a polypropylene core for added strength. Embedding and sealing each end of the pleated media in this fashion fuses the three components together forming a unified end cap and gasket.
