Which Reverse Osmosis unit?

[rica5tully]

I live in an apartment and need to buy a RO unit that will hook up to the kitchen sink and be used just when I do water changes.

I'm thinking about a unit from Air Water Ice that is rated at 75 GPD (although I know it won't do that much).

Which units do you all recommend? Are they all about the same?

Will hooking them up to your sink damage anything if you only use it twice a month?

Thanks.

I was going to order that unit from AirWaterIce. It's called the Mighty Mite. It's a cool unit, but if you have chlorine or chloramine in your water, then you won't get much help. I think the Mighty Mite removes 90-98% of the disolved solids from your tap water, and doesn't have DI. The Typhoon III has that extra layer of carbon that helps with chlorine. How big is your tank? I don't know about you, but 1-2 gallons per hour is annoying if you have to generate a significant amount for a water change for a large tank every week. That's what made me buy the Typhoon III instead. A lot of people seem to love the Typhoon III unit here and on Reef Central. I don't think any damage will come to your sink if you use the Mighty Mite twice a month.

How much is the Typhoon III? Did you get that on Air Water Ice? Did it come with an attachment for the sink or did you have it permanently installed?

I was actually thinking about their "Compact" model. It's rated at 75 GPD (the Mighty Mite is only 25-50) and is a 4 or 5 stage. It's listed at $140. What do you think?

Ooopps. The Typhoon III is the unit that you're talking about, not the Mighty Mite. My fault. Anyways, I did order the Typhoon III from AirWaterIce. I should be coming in on Monday. It's a five-stage unit. It was highly recommended by the people at reef central, which is another great forum. I was told that I could connect it to the sink or hose with the correct attachments, which I ordered. If you do order it, make sure you order the faucet adapter and/or hose connector with it. If you want to make sure that you could do a temporary attachment, you could give them a call or email them. I like how it comes with the psi gauge and a TDS measurement device. If you wanted a higher output per day, then you could switch the membrane from the 75gpd high quality output to the 100gpd high output membrane for no additional cost. I think the 100gpd membrane removes a little less dissolved metals, but your DI should take care of the rest. The only problem is that you'll be using your DI more, which means you'll be replacing it sooner than later.
