Hi

How often do you change your chlorine filter in your RO unit?

The reason for my question is that the packaging from RO-MAN (Coconut Carbon (CCB) filter) says that it should be done every 3500 gallons or 6 months (whichever is sooner) and done more regularily if your water has a more high chloramines level.

If we have a daily water useage of 400l and waste of 3 to 1 in its processing, then my calculation is that the filter should be replaced every 9 - 10 days.

Mines been in for 2 months now and the previous filter was in for 6 months before replacing it.

Hi
I think the figure is product water not total water passed through the filters

I change mine 6 monthly (it's a 20 inch one).  Maybe a 10 inch one would need to be changed more frequently but I don't know. I don't know exactly how much water I produce in 6 months but it must be around the 40,000 - 50,000 litre mark.

Hi Shiner,

I forgot to mention that it was a 10" cartridge.

Funny thing is that during last summer I had to repeatedly clean the green algae out of the tanks on my trailer -  that filter had been in my RO Unit for a least 7 months by then. So it must have still been removing chlorine from the water.

We used to dose the swimming pool every night with Chlorine in South Africa to keep the pool water clean and algae free so would presume the same principle would apply.

In that case not sure about the 10".   It's important to get it right though as you could wreck the membranes if you leave it too long.

There is a vast difference between the levels of chlorine that you would need in a swimming pool to what would be exceptable coming out of your taps.
