The IL7 Whole House purification system utilizes a main vessel that must be physically emptied and re-packed with new purification media when required.

The parts and media required for this repack consist of gravel, 5 micron filter pad, granular activated carbon and KDF.
The repack can be done on site if required, and must be performed by someone who is knowledgeable and experienced in the workings of the H2O International IL systems.
