Description
This Crystal Quest replacement pack holds the three 4-5/8" x 20" prefilters for 4,000 and 5,000 GPD whole house RO systems, with complete packs that add the 4" x 40" RO membranes. The prefilters remove sediment down to 5 microns and reduce chlorine and chloramine before water reaches the membranes.
Highlights
- Three-stage prefilter set: 5 micron pleated sediment, SMART multi-media and 5 micron coconut carbon block
- Reduces chlorine and chloramine, which protects the chlorine-sensitive RO membranes
- SMART and carbon media also reduce volatile organic compounds, other organic chemicals and some metals
- SMART and carbon block cartridges rated 6 GPM at this size
- Cartridges fit 5" x 20" Big Blue housings

- Prefilter pack contains the three cartridges only, with no RO membrane
- Not a complete set for the 7,000 GPD system, which uses four prefilter housings
- Prefilters do not remove dissolved salts or TDS; the RO membranes handle these
- Not designed for hardness above 15 gpg or iron or manganese above 0.05 ppm; these need separate pretreatment
- The membranes tolerate less than 1 ppm chlorine, and chlorine damage is permanent
- Check the size printed on your current membranes before ordering; actual filter life depends on feed water quality, system configuration and usage
