RO-DI unit

[Andrew]

I need to order a ro.di unit this weekend because I have been putting it off. I was recommed this one but is there anthor good one thats on an RC sponcer site or ect thats nice and under $120. I dont need that much. I will only need about 20-30 gallons a week.

I recommend an air water ice typhoon III.

I still prefer the vertical DI canister. With horizontal ones, water can bypass the resins over the top of resins bed. I don't see how two DI canisters solve this problem. Get the correctly designed ones from AirWaterIce.com. Typhoon I is $160, same canister configuration.

Do you guys have links to where I can buy them?

I researched alot of RO/DI units this week. I settled on the TYPHOON III from airwaterice.com I paid $199, a little more than I wanted, but I think it was a very good choice. I received alot of good replies recommending this unit.

I looked at that one but that would be $175. Maybe ill have to spend a little more.

It's almost identical to AirWaterIce's Typhoon I unit ($160), where there is no bells and whistles. I believe Typhoon uses the best RO membrane (from Dow Chemical), and Melev uses the GE version. I also prefer the Typhoon's filter configuration: 10 micron -> 5 micron -> 1 micron for the best pressure drop. Melev's unit is 5 micron -> 10 micron -> 10 micron.
