    Does tankless RO's remove PFOA/PFOS?

    Tankless reverse osmosis (RO) systems are designed to remove a wide range of contaminants from water, including PFOA (perfluorooctanoic acid) and PFOS (perfluorooctanesulfonic acid). PFOA and PFOS are a type of per- and polyfluoroalkyl substances (PFAS) that are commonly found in water supplies. RO systems use a semi-permeable membrane that can effectively remove these harmful substances, along with many other impurities, such as heavy metals, chlorine, and various chemicals.

    How often filters need to be changed?

    For households below 6 persons service once a year is enough.

    What gives better water quality tank RO or tankless?

    They are equal.

    Can I connect my RO system to a fridge/chiller/heater?

    Yes, we can provide this service

    I heard NYC water is good. Why do I need a filter?

    NYC water is good by itself, however, NYC pipes are very old and made of lead and copper. So major water contaminants of NYC are chlorine, lead, copper and also a high level of sediment.

    A separate water problem is PFOS/PFOA, it’s a new contaminant that may cause cancer and RO filtration is the most effective way to remove it.

    Do you have a warranty on your systems?

    Yes, all our Tankless RO systems have a 3 years warranty.
