Coconut shell carbon block filters are specifically designed to provide the highest level of cyst and lead reduction. 
 
Carbon filtration is an inexpensive and effective way to remove chemicals and contaminants commonly found in tap water. Aries FilterWorks carbon block cartridges are an ideal choice for taste and odor control, chlorine/chloramine removal, and organic, lead, and cyst reduction.  
 
Each block is wrapped with a polypropylene outer layer and netting to prevent premature clogging of the carbon block.
