If you are interested in splitting up the cost we can order a case lot of the pre filters. This comes with the below for $74.95 enough for three changes each for a 3 pre-filter setup like mine, or if someone else wanted to get in it would be two each and the price would only be $25 each. They also have the RO membrane for $49.95 if you would need it also. PM me if you'd be interested, if not I may see about setting up a group order.
