What one would you recomend I'm not familiar with rodi units at all sry

prsnlty · May 31, 2014

Get a 3-4 stage unit from bulk reef supply and get the faucet adapter set. A 5 gallon bucket from lowes or any home store and a shut off float to put on your bucket so it doesn't overflow in case you forget it's running. Just make sure you have the di chamber on that ro unit.

I love my Typhoon Extreme 3 from Air, Water, Ice, but the Bulk Reef Supply units are supposed to be pretty good too. Make sure you get one that has a DI section, not just RO.

What about the typhoon 5 stage seems about the same as the typhoon 3 minus the GPD but i only need it for a 30 gallon so id go for the lowest GPD since its way cheaper but that is the only difference i see unless there's more to it?

Haven't heard of the brand but does it have di ?

Also, here is the link for tge auto shut off

Yes there can be a huge difference if it's meant for drinking water. And some membranes filter out more stuff than others.

Oh no it's the same company but of it being the extreme typhoon 3 its just the typhoon 5 stage both rodi

Sorry for the many posts. On my phone.
I have this bathroom diverter for the bathroom and it's perfect. No taking it on and off needed.

I looked up the 75gpd version. Typhoon5 comes with auto shut of and tds meter in some stores. Though I didn't see a price except on amazon. Cost a little more thank the link I gave you but makes up for it in extras.

I think it's almost the same. I suspect the 3 is a little bit different design from the normal 5 stage. If you want, I could go compare them for you, but it looks like you're going for the one from BRS?

Go with as high a GPD as you can afford. You'll only get its rated GPD at ideal water pressure (I don't know about you, but my water pressure tops out at about 40psi, whereas you want about 60 - and in an apartment, it's likely to be markedly less than ideal.) And trust me, it's excruciating to be waiting hours for water to make when you have an emergency.

The Air, Water, Ice units are sold directly from the manufacturer. airwaterice.com

prsnlty · May 31, 2014

+1 on what Eienna said about the bigger gph the better. 75 to 100 gph due to your apartment water psi. But 75 gph should do it.

I owned a Typhoon III and sold it for a Spectrapure MaxCap. No comparison at all, light night and day difference. DI went from 150 gallons up to 830 measured gallons on the very first cartridge.

I am currently in the process of buying a RO unit. I am looking at the one from BRS 4 stage plus so it has the TDS meter with it. It's not too expensive so it might work out for you as well

AZDesertRat · May 31, 2014

The BRS units use too coarse of sediment filters to protect the downstream filters and membrane so they do not last as long or work as well. The result is more frequent replacements driving the cost of ownership up. Also pass on the inline type TDS meters, they lack the accuracy of a good handheld which costs the same but are much more versatile. To check a RO/DI you need 3 TDS readings and the inline only gives you two so you cannot calculate your rejection rate.

Mike J. · May 31, 2014

I have the BRS 5 stage unit and I have switched out the sediment filter from the 5 micron that comes with it to the 1 micron (.06) and I change that filter every time I change the DI resin, which is about every six months or when my water reads 1 TDS. I change the carbon filters (the first one also switched out) every year and the RO filter every two years. There is a lot less rejection this way and I get water three times quicker than original.

I have a degree in Marine Biology (water), but if I needed advice I would ask Desert Rat. He is right about the BRS unit not being set up perfectly.
