There are a number of people who are interested in filtered water that is bacterially pure, has chlorine and other chemicals removed or reduced, but for a variety of reasons they refuse to consider reverse osmosis. There are several reasons why they might not want RO water:
- They may be violently opposed to any water waste - I think that is short-sighted in this case, but... OK;
- They may not have space for storage of RO water if they have higher volume; and
- They may be opposed to taking the minerals out of the water.
