Our FILMTEC™ commercial reverse osmosis membrane elements for tap water (100-1800GPD) offer the industry’s most reliable filtration features and performance. Advanced membrane technology and automated fabrication allow these elements to deliver consistent water purification that equipment suppliers, water treatment dealers, and residential customers can rely on. These membranes deliver excellent performance in terms of flux, salt and organics rejection, and microbiological resistance. They can operate over a pH range of 2 to 11, are resistant to compaction and are suitable for temperatures up to 45°C. Their performance remains stable over many years, even under harsh operating conditions.

These elements are the official replacement membranes for the APEC Pro, Logic Controlled, and Whole House RO
