Coconut Shell Carbon
C Myers - Pennsylvania (Saturday, October 29, 2011)
This filter is a blessing! We have sulfur water and go through regular carbon filters in about 2 weeks and they cost about $35 each at Lowes. Heard that coconut shell carbon is better, so gave this a try. It's doing an excellent job. Two weeks have passed and still no odor. It's great! We will continue to buy this filter and sign it's praises!!
