Choosing the right filter insert can be difficult if you're new to these products. Read below to learn more about what the product does and the different options available.
Sump filters use universally sized housings that can contain different types of filter inserts. The type of filter insert that you choose should be based on your water source, contaminants, and what your desired result is.
Anything with activated carbon is designed to reduce Chlorine taste and odor and should be used on public water supplies. It’s not recommended to be used on wells with no disinfection.
All filter inserts have a micron rating that tells you what size particle they will filter down to. The lower the micron rating, the tighter the filtration. This also means that the tighter you are filtering, the shorter the potential filter life. Some well systems with high levels of sediment will have two sump filters in a row. The first will contain a prefilter with a larger micron rating and the second will contain a polishing filter with a lower micron rating. By doing this, homeowners can better protect the filters from fouling and extend filter life.
Filter Insert Options:
FACT (Flow and Capture Technology®)– Generally best for public water with low amounts of sediment and high Chlorine. Contains activated carbon and highest level of filtration.
Carbon Block - Generally best for public water with low amounts of sediment and high Chlorine. Contains activated carbon.
Pleated – Surface filter used to reduce larger sediment. Will not reliably reduce red water (Ferric) iron. Will not reduce chlorine taste/odor. Lowest level of filtration. Often used on well water as a prefilter.
String Wound – Surface filter used to reduce medium sediment. May reduce red water (Ferric) iron. Will not reduce chlorine taste/odor. Often used as a single filter on well water.
Melt Blown - Surface filter used to reduce fine sediment. May reduce red water (Ferric) iron. Will not reduce chlorine taste/odor. Lowest level of filtration. Often used as a polishing filter on well water after a looser prefilter (such as a pleated).
