System 1 Replacement Water Filter Cartridges

These advanced carbon block water filters have a nominal 5 micron rating and offer maximum absorption of Chlorine and other chemicals due to the large surface area (within the pores of the filter) that is approximately 14 times greater than normal loose fill GAC water filters and not subject to channelling which is a common cause of failure for regular GAC filters.
This under sink purification system removes Chlorine plus Herbicides, Pesticides and many other dangerous chemicals and all particles over 5 microns in our water such as sand, silt, rust etc.
Now you can enjoy crystal clear water straight from your tap with this excellent fresh water filter system - like bottled water but at a fraction of the cost.
