This is a complete Carbon Block Water Filter System. It is a self-install system that fits neatly under sink.

GAC Carbon Block Water Filters - How they work.

These advanced Carbon Block Water Filters have a nominal 3 micron rating. They offer maximum absorption of Chlorine and other chemicals due to the large surface area within the pores of the filter. The design gives approximately 14 times greater surface area than normal loose-fill GAC water filters. Another benefit is that they are not subject to channelling which is a common cause of failure for loose-fill GAC filters.
This under sink purification system removes Chlorine plus Herbicides, Pesticides and many other dangerous chemicals. It will also remove all particles over 3 microns in your water such as sand, silt, rust etc. 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.
