Thank you that we got our Berkey in time. We don't know if you have heard what is going on here in Australia, but we don't have to worry about our drinking water. We are so safe.
Kind regards, Ralph S

Features
    • Dow Filmtec TW30-1812-75 Reverse Osmosis Membrane Instructions:


    • After installation of the Filmtec TW30-1812-75, the first full tank of permeate should be discarded. Do not use this initial permeate for drinking water or food preperation.


    • Keep the TW30-1812-75 RO element moist at all times after initial wetting.


    • During prolonged system shutdowns, it is recommended that the Filmtec TW30-1812-75 membrane elements be immersed in a preservative solution. This is to prevent biological growth.


    • The Dow Filmtec TW30-1812-75 membrane shows some resistance to short-term attack by chlorine (hypochlorite). However, continuous exposure may damage the membrane and should be avoided. Most systems have prefilters to filter out the chlorine. Be sure to change these filters regularly to preserve the TW30-1812-75 Filmtec reverse osmosis membrane.
