The Platinum Wasser SETULTRA3 is a replacement filter set for 5 stage reverse osmosis systems that use standard 10″ prefilter cartridges. It is suitable for routine filter replacement in compatible home reverse osmosis systems and is also used with the Platinum Wasser ULTRA5B.

This 3 piece set includes a 5 micron sediment PP cartridge for the first stage, a carbon block cartridge for the second stage, and a 1 micron sediment PP cartridge for the third stage. These are the prefiltration stages used before the membrane stage in many standard reverse osmosis systems.

Its compatibility with standard 10″ filter housings makes it a practical option for customers looking for replacement filters for a wide range of 5 stage reverse osmosis systems, while also giving a direct fit option for the Platinum Wasser ULTRA5B.
