While lab specifications like "2,400 gallons per day" are useful benchmarks, they're measured under perfect conditions — ideal water temperature, precise pressure, and clean water. These are standardized conditions to demonstrate the membrane's stated test performance.
Real-world performance varies based on your specific water conditions, temperature, and system configuration. That's why it's more important to match the existing membrane's model number and size — this ensures you get a replacement that's properly engineered for your system's design specifications.
