Will not let it get this high again.

Little confused ...
When my RO water started to smell of chlorine, I immediately changed both my filters ... pre-filter and carbon filter
I saw no change in my chlorine smell after new filters ...

I was trying to finish my post before it got wiped out

You can get up to 6 months out of a carbon filter, and 3 years from a RO filter

It all depends on your usage ....

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 ....
