Merlin RO Membrane Element 

Merlin Membrane Elements are the core of the Merlin Garden Pro reverse osmosis process. 

They capture the dissolved minerals in the water supply that can harm your hydroponics garden, such as iron, calcium, and magnesium.

When the Merlin Garden Pro pre-filters are kept clean and inlet water remains reasonable, the Merlin Membrane Elements can last up to four years before replacement is needed!

These Merlin Membrane Elements are the replacements for the Merlin Garden Pro reverse osmosis system. Each system holds two Membrane Elements - both should be changed simultaneously for best results.
