Worth knowing

Under-sink, with a 3.2-gallon tank. Brondell advertises a 1:1 clean-to-waste ratio, but its performance data sheet gives a 29.1% efficiency rating, which is recorded. The spec sheet gives the membrane the system's 300-gallon certified capacity rather than a membrane life, so only its 24-month interval is used.
