RO water filter system replacement cycle

[smiles2000]

The RO water filter system I ordered was for my father, who lives alone and is away from his home at least 25% of the year. Therefore, his usage will be very very low, at least compared to a family of four.

I’m pretty sure that when suggesting a replacement cycle . . . every 3 months for the sediment filter, every year for the carbon filter, etc . . . that assumptions are being made about usage. Are these filters each rated for a number of gallons? Can I put a water meter on the line to measure usage and change the filters based on that data? What if it takes my father 3 years to achieve the rated life of the carbon filter? Will it degrade over time, or will it be ok?

Yes, the filters will last longer for him. It is based on water quality as well as usage, so I wouldn't worry about monitoring usage precisely because the water quality is another variable. I'd recommend 6 months for sediment, 18 months for carbon, and 2.5 years for the membrane for him.
