The FILMTEC-TW30-1812-50 is comparable with the following part numbers



  1. After installation of the Filmtec TW30-1812-50, the first full tank of permeate should be discarded; do not use this initial permeate for drinking water or food preparation
  2. Keep the Filmtec TW30-1812-50 RO element moist at all times after initial wetting
  3. During prolonged system shutdowns, it is recommended that the Filmtec TW30-1812-50 membrane elements be immersed in a preservative solution to prevent biological growth
  4. The Dow Filmtec TW30-1812-36 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, so be sure to change these filters regularly to preserve the TW30-1812-50 Filmtec reverse osmosis membrane.
  6. Change your filters and membrane at the recommended frequency
  7. Clean your system occasionally with a product like Sani-System SS96RO, an easy to use, pre-measured, reverse osmosis system sanitizer (purchasable separately)
