Over doing the RO/DI

I'm having trouble choosing a RO/DI unit, its not a money issue its a practicle issue. I see 3-4-5-6-7 stage unit now. And some 7 stage unit are cheaper that than a 4 stage unit. So i'm perplex as what use is a 7 stage can actually provide than a 4 can't. To me its seems a waste of filters or an unecessary expense. Any advice on whats really important and whats not, because i'm lost, lol. Thanks for your time.

 

I have a Spectrapure MaxxCapp system. This is one of their best units and one I strongly suggest you get.

Generally if the unit has multiple cartidges of the same media then you are wasting money on extra pieces that should not be needed.

 

Agreed. All you really need is a system with a sediment pre-filter, carbon pre-filter, R/O membrane, and either 1 or 2 resins.

 

Wow just checked the Spectrapure MaxxCapp system on you tube , great stuff then i checked on the net its discontinued then i found out the price on amazon wow fair chunk, lol $ 300 . Its loaded with features and options though.

 

You get what you pay for as many in this hobby know.

 

Using spectrapure here too. love it.

i got then 180gpd version, it saves so much time. Also def get one with booster pump.

 

The number of stages means little. The quality of those stages means alot.
Spectrapure units,filters, and membranes are top quality.

 

I'm also using the 90gpd Spectrapure MaxCap CSPDI. I've had it for 8 months now, and I love it!! Also, if you get the one without the newfangled auto flush system, it's quite a bit cheaper.

 

I just use the under sink "drinking water" RODI I have for water changes. It works fine for my 14 gallon Biocube.
It's a GE Avantapure 5 stage with a 3 gallon storage tank, it came with my water softener system.

 

spectrapure, max cap auto flush 180gpd and adding a booster pump. Great tanks start with great water.
