GenX, Perfluorooctane Sulfonate (PFOS)
Perfluorooctanoic Acid (PFOA)
Perfluorooctanesulfonic Acid (PFAs)
Perfluorinated Chemicals (PFCs)


The EPA lists carbon filtration and reverse osmosis - technologies found in Home Master Reverse Osmosis systems - as approved filtration methods for removing GenX, PFOS, PFOA, PFAs and PFCs.

“The under-sink reverse osmosis filter is the most efficient system for removing both the PFAS contaminants ... and the PFEAs, including GenX,” said Detlef Knappe, the professor of Civil, Construction and Environmental Engineering at North Carolina State University

Additionally,
Home Master RO systems utilize a more advanced catalytic carbon media to provide superior filtration as opposed to standard granular activated carbon.

1,4 Dioxane

While more research needs to be done on 1,4 dioxane removal, early authoratitive studies have shown a 50% - 97% removal rate when reverse osmosis and granular activated carbon filtration technologies are combined, and under various water conditions. Home Master Reverse Osmosis Systems have not been tested for 1,4 Dioxane removal, but contain similar filtration technologies as those tested, and may be the the best option for home water purification.
