Maintenance
It is highly recommended to change your filters periodically to
maintain the highest level of filtration from your RO system. Changing
your filters regularly can also prolong the life of your RO system. The
table (below) shows how often it is recommended to replace each
filter/stage in your system. This is dependent upon water quality;
water hardness & particulates may result in filters being changed
more regularly than shown:
