how do i know what replacement filter to get for my RODI - whats the common measurements? universal? length, diameter? I know the type i need, just not size...

I got it at BRS about 9 months ago and my color changing resin filter is starting to change color - may have something to do with my diatom bloom
 
What unit do you have? 10" is the common size. Tell us more about your DI resin is the color change just at the bottom? I have an extra DI cartridge if you need one now it needs a home before it goes bad.
 
Economy 4 stage RO & DI system. It takes a sediment filter, a 5 micron CTO/2 Carbon Block, and a color changing DI resin filter.

Yes, just at the bottom it is changing color

75 GPD RO/DI 4 Stage Economy System


is this it</em>
 
The one on top is the 3rd stage if taken care of properly it should last 2-3 years depending on TDS. We probably have the same water source.
 
whats a average reading for a tds meter before you should change ur filters?

I need to know where the TDS readeing is coming from, source water, before RO after RO before DI after DI? For sediment and carbon a Pressure guage is a good signe to judge when the prefilters are starting to clog.
