Water travels radially and enters the cartridge through the outer 30-micron layer and exits through the inner 1-micron layer. Because the APR-4N1 gradually filters ALL sizes of sediment from big to small, each layer only has to filter its designated size sediment. This is different from a single section cartridge.
Microns are a unit of measurement. They refer to the size of the sediment passing through the cartridge. The smaller the micron the smaller the sediment.
The APR-4N1 is our BEST VALUE sediment cartridge for its quality and durability.
|Size||9 ¾" (filter only)|
|Max Temp||85°F (Use cold water line only)|
The Super 4-in-1 Sediment Cartridge gradually filters ALL sizes of sediment from big to small, each layer only has to filter its designated size sediment. It is wider than most sediment cartridges to accommodate FOUR SEPARATE FILTER ZONES of 30,15, 5, and 1 microns for enhanced filtration and longer life than traditional 1 micron rated cartridges.
|Filter Section||The Super 4-in-1 Sediment Cartridge (9 ¾"): APR-4N1 should be replaced every 12 months* or when water pressure drastically reduces.
*Note For some customers, depending on your water quality and the size of the sediment in your water supply, the APR-4N1 may need to be replaced sooner than 12 months.
