What is the right RO/DI system for me?

[Computatrum_Monstrum]

I have well water and a TDS measure of 176 PPM. What would be a good choice for a RO/DI system that’s not going to break my bank?
Thanks in advance

No ro buddy

look at BRS Unit, air,water and ice- typhoon …… and spectra pure

hands down BRS 4 stage. Great price, solid unit, and very easy to find and cheap replacement filters and parts. There is a reason it is so popular.

Brand makes no difference. Well water use CTA membrane and i would recommend double prefliters and carbon filters prior to going into the RO membrane. i prefer double di stages after and rotate them
whats your well pump pressure at? ideally you want it around 75-80 psi if you can set your system like that or add a booster pump. If the pressure is low the ro/di water production is low per day.

RO/DI Basic Guide

There are always a lot of questions regarding which RO/DI setup do I need, how many stages, how do I know when to change filters/membranes, I’m getting a weird TDS value, etc. Hopefully this clarifies a few things and helps some of you out one day. My first recommendation would be to find the...

With a TDS of <200 you would be good to run dual DI to reduce waste water and increase daily RO production.

Any idea of the makeup of your well as far as contaminates?

Incoming pressure?

I'd go with at least a 6 stage, sediment, dual carbon, RO (if you want less waste and more production dual RO), dual DI.

You could get start with a single carbon and single DI if you wanted to start basic and add on additional canisters later.

4 stage would work, just require more effort on your end for monitoring so that you change the filters out at appropriate times. Dual carbon and DI give you extra wiggle room on change outs and ensure you get anything the first filter misses.

Have you checked your well for high CO2?

If not you may want to perform a pH test and determine. High CO2 will quickly exhaust your DI membrane.

@KStatefan is better than me for degassing information if needed.
