The Matrikx +1 carbon filter which we normally recommend removes MTBE from water. However, we also sell a Matrikx +5 filter made from Coconut shell which is supposed to be better at removing MTBE. The price for either filter is $15 plus postage. Please note that while the Matrikx +1 is good for 20,000 gallons of chlorinated water, the Matrikx +5 is only good for 6,000 gallons of chlorinated water.
