**Q: is there a catalyitic carbon filter avaiable to remove chloramines?**
A: Chloramine is removed from water with essentially the same strategies that are used to remove chlorine. This means that carbon filtration is the best removal method and filter carbon does indeed remove chloramine. The problem is that it takes more carbon and more contact time to do the job. In practical terms this means that if your City disinfects your tap water with chloramines you'll need to get a larger and better carbon filter than you would need if chlorine alone were used. All our products use activated carbon so are capable of removing chloramine.
