[smelly shelley]

I have had a ro system at home for about 2 years now. I havent changed any of the filters in side ,
and it has run none stop since i plumbed it in. How often should i change them.

Would they Ben?

It really depends on what your pressure readings are, what your TDS readings are, and how many gallons of water you've made since the last filter replacement in comparison to when the manufacturer recommends you replace the Carbon filter...

If your TDS is 1/100 or less than the tap water reading, when measuring the membrane output before any TDS cartridge, the membrane is still fine. If it's higher, flush the membrane for half an hour, then give it half an hour to settle down again. If it's still higher, it's new membrane time If you pressure into the unit is fine, but pressure into the membrane is lower than into the unit and the flow out of the use pipe is dropping, it's new sediment pre-filter time If you have produce the same amount, or more, than the Carbon filter is designed to filter, it's time for a new one of those. If you run TDS and the final TDS reading after the cartridge is anything more than 0, it's replacement DI resin time.

As you see from above, you cannot say what needs changing when without readings for TDS, Pressure and the amount of water that's been made compared to what the carbon cartridge is rated to make...

All the best
