APEC RO-90 Filter Replacement after 2 years | Reverse Osmosis System RO90

The APEC RO-90 reverse osmosis filter system has been working wonderfully for the past 2 years.

This is a long-overdue pre-filter replacement, but since the sediment in our water is pretty low, the flow is still good enough for general use. The pressure had dropped enough that the storage tank would only hold about 2 gallons instead of 4-5 gallons. The TDS (total dissolved solids) was still very low, so the RO membrane filter is functioning well, so the pressure drop is likely being caused by the clogged pre-filters.
