Reverse Osmosis Membrane Elements RO-3012-400

The 3012-400 model is the most commonly used membrane in most standard small RO systems or home water purification machines. Capable of producing 400 gallons of clean fresh water per day with only 100 psi pressure. It is ideal for home use, producing enough clean water at a low cost. To achieve the recommended percentage of RO water salts in your water, the membrane removes 97 percent of the salt solids in the water, leaving it with a pleasant taste and a low TDS level.

Category Introduction

The Domestic RO Membrane 3012 is a high-flow, standard-size filter element used in home reverse osmosis water purification systems. Its larger, longer design is designed to meet the needs of households seeking high-efficiency water production and long-lasting filtration.

As the core component of a water purification system, the Domestic RO Membrane 3012's core function lies in its highly efficient and precise physical filtration. It effectively removes total dissolved solids (TDS), heavy metals, bacteria, viruses, and other trace organic matter from water, significantly improving the purity and taste of drinking water. This series of products is typically available in various water output specifications (e.g., 3012-400, 3012-600, etc.), with the number representing the daily water output in gallons. Users can choose the filter based on household size and water usage. Thanks to its larger membrane area, the Domestic RO Membrane 3012 typically achieves faster water production and a longer replacement interval while maintaining high desalination rates, providing stable and reliable water purity for households.
