View Full Version : Need a filter update?

Hi, you guys have been so helpful before.

Wondering if I need some new filters and which ones. Here's my situation:

I have a 75 GPH RODI system with three prefilters, one RO membrane, and a DI resin filter. I'd say all filters have been replaced in the last year, at different times.

I have in inline TDS meter that has the following readings:

- Out from RO Membrane: 005
- Out from DI: 005

So at minimum my DI needs to be changed out. I think my RO is relatively new so maybe just an updated to my 3 carbon filters?

Oh my water pressure is about 50PSI I think? I'll have to check but its usually right below optimal for getting the best RO performance (learned that from you guys :-) )

I would just replace the di if my psi is 50.

I replace carbon and sediment when the pressure drops or 8 months pass. As the sediments stop up the psi will go down. This is the tell tale of those stopping up.

But u ain't gotta wait. Proactive is better than reactive. 8 months is as long as I go.

Here is what you want to order color changing and non color changing both produce the same efficient and color change offers eyeball heads up to exhaustion.
