Time to change sediment filter?

[NormanB]

What do you all think?

Good to go for a bit more or change it out?

Thanks

I still see white, but for the effort of having opened the canister and removing it, may as well just put in a new one.
I go by my pressure guage on the membrane input. When it drops 10psi from when my prefilters were new, I change the sediment filter and carbon blocks.

Sounds good.

Thanks!

It's good to have a Tds meter in line with the filters. I second the you already took it out you might as well change it.

I have 2 TDS meters...

1 before the filters and 1 after the DI.

I think I'll add another after the RO membrane just to monitor the membrane health.

What was your output TDS reading?

Generally, visual cues are the last thing I look for with RODI filters. I change filters as soon as the TDS reading goes above zero

You change your sediment after a 15% pressure drop. Probably best to replace every 6 months.

Thanks the the schedule suggestions

TFS was 0 after the DI

In coming TDS ranges from mid 80's to mid 120's

If you are getting zero TDS and pressure is good I would just keep rolling with the same filters.

A great side benefit of having the meter on an RODI unit is getting maximum life out of the filter cartridges...
