SLD-PRE-5020
50–20 Micron
Heavy-duty pre-filtration for high sediment applications. Removes sand, silt, rust, and large debris to protect downstream filters from rapid clogging.
Ideal for
Well water, rural areas, high sediment conditions
Removes sand, silt, and debris
Protects downstream equipment
High-capacity, easy replacement
SLD-PRE-2010
20–10 Micron
Balanced pre-filtration for moderate sediment levels. Removes silt, fine rust, and organic debris - ideal for moderately turbid municipal or well supplies.
Ideal for
Municipal water, suburban areas, general use
Removes fine particulate
Protects downstream equipment
High-capacity, easy replacement
SLD-PRE-1005
10–05 Micron
Ultra-fine pre-filtration for maximum water clarity. Protects carbon block cartridges from fine turbidity that shortens service intervals significantly.
Ideal for
Low sediment water, high clarity applications
Removes ultra-fine particulate
Protects downstream equipment
High-capacity, easy replacement
Why upstream prefiltration matters
Protect the filter that protects everything.
Not every home needs a prefilter - your dealer will test your water and specify based on actual sediment load.
01
Extended Primary Filter Life
Carbon block filters like PALADIN and GUARDIAN clog faster when water carries high sediment loads. A prefilter upstream catches larger particles before they reach the carbon block - significantly extending the service interval and protecting your investment in the primary filter cartridge.
Maintained Flow Rate
Sediment accumulation inside a carbon block filter reduces flow rate over time. Pre-filtering prevents premature restriction, maintaining peak flow performance - 8 GPM at the primary filter - for the full rated cartridge life.
02
03
Sediment-Specific Filtration
Carbon block filters are optimized for chemical and microbial removal, not high sediment loads. Using a dedicated sediment prefilter lets each stage do what it does best - sediment capture upstream, health-contaminant removal downstream.
