So, here's what I've learned ....
You get 3 months out of of your pre-filter, 3 months from your next stage, 6 months out of your carbon filter, and 1-3 years out of your RO membrane (depending who you talk to)
Good thing lots of members give us lots of information so we can gauge our filters ....
When your RO filter turns brown, you should change it;
When pre-filter turns brown, it's time to change it
When a Carbon filter turns black, it's well over-due
C'mon, don't ask when an RO membrane is past due ....
