Advice on decent RO/DI unit?
- Thread starter sodaman
- Start date
After speaking to Bryan I have ordered the Optima CA unit and he is even going to have it pre-setup for my configuration. I will have to agree with everyone that the customer service from Bryan is top notch. He explained everything about how I need to hook it up for my configuration and he answered every question I had. I will let you guys know what I think of the system when it arrives and is hooked up.

so it seems that if my water is not treated with chloramines (anyone know how to find out) then the Optima Chloramine Advanced is not necessary.
so my decision is between the Optima Pro and the Typhoon III. can anyone explain the differences between these 2 models????

Just a quick glance at the 2 units...

The most glaring difference is that the typhoon has an extra carbon block stage--probably not an issue unless it starts showing blockage (by a pressure drop) prior to the reccommend 6 month replacement cycle... if it does then you might want to add an extra stage (which should not cost much) and step down the filter after the sediment filter (5 micron first stage, 1 micron second) to share filtering... once again.. this might be adequate, probably dependent upon your source water.
other then that they look to have similar features and include a TDS meter-- the optima doesn't say it uses a Dow filmtec but I think it does. The Optima says it has a membrane % monitor-- not sure if this shows the RO rejection in percent (TDS reduction) but it sounds like it does... would tell you when your membrane goes bad (but that should not happend for several years)--
The differences look pretty small... I don't think you will go wrong with either...

Percent monitor
Percent monitor
The actual use for the percent monitor is to notify you of variables in the membranes performance. There is a thing called TDS creep where the number is higher than normal at startup and this tells you when that starts and ends. As a benefit it will also tell you when the membrane is no longer working
You also get a heandheld meter for actual readings.

Call your local water utility and request a copy of their latest "Consumer Confidence Report". They are required by law to provide you a copy. This is just a fancy name for their annual water quality report and they must list everything that was tested in that time period and what the results were. Most medium to large utilities have this information online also.
Don't see mine on line but did find this (below) Any issue with this stuff?
The six chemicals added to the water drawn and pumped from Lake Michigan to the Water Filtration Plant are:
Aluminum Sulfate - to eliminate suspended solids (turbidity) from the water.
Carbon - to eliminate objectionable taste and odors in the water (typically related to algae).
Chlorine - for disinfection and to kill organisms and pathogens found in the water
Fluoride - to help prevent dental caries.
Poly-Orthophosphate - to provide corrosion control for users with lead service lines or solder.
Sodium Hypochlorite - to eliminate zebra mussel infestation in the raw water intake lines and to enhance contact time (CT) for control of microbials.

A good RO/DI will handle all those no problem if you have good carbon filters ahead of the membrane.

Re: Percent monitor
What about your RO membrane?? Dow FIlmtec?? Rejection rate??

Any of the AWI or Purelyh2o units will handle normal water conditions no problem. It all boils down to what features you want and what you are willing to pay up front. It has been my experience, if you pay a little more in the beginning the long term cost is much less. That means get a unit with the best membrane (75 GPD Dow Filmtec), large capacity refillable DI and things like an autoshutoff valve, TDS meter and pressure gauge.

I installed my Optima CA this weekend and this unit is awesome!
Definitely $ well spent. Thanks Bryan.
I enjoyed testing all my different water using the handheld probe. Interesting test outcomes.
Normal faucet water = 300+ TDS
Water from refrigerator door (filtered - about 3mths old - indicator light shows filter is good) = 150 - 200 TDS
Water after Optima RO chamber = 1 to 3 TDS
Water after Optima DI chamber = 0 TDS (sweet)
This unit has everything you need. The only thing I should have added to my order was a float valve to use in my water container (trashcan) to shutoff when container is full. Resulting from the test results from my refrig. filter, I will probably add a drinking water storage tank, faucet & taste/odor filter and plumb it to my kitchen sink & refrig. This addon option looks relatively inexpensive.
