Anyone have this RO system? How often do you change the filters etc?

I've had it for about 2 years and I've only ever changed the DI on it, probably need to do a full change of the filters.

Looking on the website and I can't see replacements on there for anything but the membrane. Some of them say replace every 3 or 6 months

Do you know where I can buy them?

I have a similar unit I got back in Novemeber, think they're all fairly similar in size and shape so maybe filters are interchangeable? Open to correction on that.

How do you find it? My output is only 3.5l per hour. I'm just going to upgrade to a 75gpd when the filters are due.
Have you checked your TDS over time?

Thanks for this, I bought a similar one from Amazon.

Yeah I find it good, just takes a bit of planning, I just turn it on the day before I am brewing, I usually work from home on a Thursday so just collect water for the weekend then. I don't have a TDS tester but I am well overdue a filter change I think. Maybe I should get one...

I work from home Thursdays too...they needn't know it's primarily a brewday every couple of weeks
Kids at school, wife at work, ideal. Kick things off at 8, fermenter filled by 12 and cleaning done by 3 and that's while answering calls and doing the day to day. They do say you should walk around for ten mins every hour and it's amazing how much you can get done in those ten(ish) minutes
