Still haven't figured it out? How much do you spend weekly buying RO water from a store? Multiply that by 52. If its more than $200 you're obviously better off buying a filter.
Membranes are sort of expensive (+$60?) but only need to be replaced every 3-5 years. Pre-filters are around $5-$15 each depending on how many you buy and where you get them from.
