Water travels radially and enters the cartridge through the outer 30-micron layer and exits through the inner 1-micron layer. Because the 4-N-1 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 4-N-1 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) |
Efficiency | The Aquaspace 4-N-1 can be used as a polishing filter for a whole house system. It can also be used in any standard 10” slim housing as seen in the counter-top and under-the-sink models. |
Filter Section | The Aquaspace Micron Multi Sectional 4 in 1 (APR-4-N-1) 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 4-N-1 may need to be replaced sooner than 12 months. |
