Description
DOW FILMTEC™ residential elements are the most reliable, consistent and highest quality in the industry. Our elements offer the best balance of flow and rejection, producing industry leading flow rates (around 20% higher) than competitive elements at similar pressures.

DOW FILMTEC™ Residential Elements Feature:
• Longer lifetimes that can reduce operating cost for OEM’s/brand owners
• NSF safety certification and ability for NSF data transfer reducing certification costs
• Fully-automated manufacturing that ensures consistent and high quality elements
• Dry shipping for convenient handling and longer shelf-life
• High quality elements significantly reduce or eliminate element Quality Control (QC) costs

• Maximum temperature for continuous operation above pH 10 is 95F (35C).
• Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow Water & Process Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure.
