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)|
|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.
