Therefore a carbon post-filter will be generally unnecessary on a quality system, even for drinking water. However, in-line GAC post-filters can easily be added or removed based on your particular water and RO system performance.

Therefore a carbon post-filter will be generally unnecessary on a quality system, even for drinking water. However, in-line GAC post-filters can easily be added or removed if needed based on your particular water and RO system performance. GAC is acceptable as a post-filter because high performance isn't needed at this stage, and also the contact time in a post-filter is significantly longer compared to a pre-filter, which increases the effectiveness. | ||
