The FILMTEC-TW30-1812-100 is comparable with the following part numbers



  1. After installation of the Filmtec TW30-1812-100HR, the first full tank of permeate should be discarded. Do not use this initial permeate for drinking water or food preparation
  2. Keep the TW30-1812-100HR RO element moist at all times after initial wetting
  3. During prolonged system shutdowns, it is recommended that the Filmtec TW30-1812-100HR membrane elements be immersed in a preservative solution. This is to prevent biological growth
  4. The Dow Filmtec TW30-1812-100HR membrane shows some resistance to short-term attack by chlorine (hypochlorite). However, continuous exposure may damage the membrane and should be avoided
  5. Most systems have prefilters to filter out the chlorine. Be sure to change these filters regularly to preserve the TW30-1812-100HR Filmtec reverse osmosis membrane
  6. Change your filters and membrane at the recommended frequency, and clean your system with a product like Sani-System SS96RO, an easy to use, pre-measured, reverse osmosis system sanitizer
