First off, you should know that anyone with some fundemental knowledge of water treatment can make one of these in their garage from catalog parts.That's exactly what this unit looks like, too.I bought it because it was cheap, but a week later I saw a better system advertised at the local home center for $20 less.
The unit I received came with a faucet adaptor.That's right, just one adaptor and it didn't fit anything in my house, so before I could use the unit I had to go to the store and get a part to mate the RO unit to a faucet.Once that was accomplished, I was able to make RO water right away, and the best I can tell, the unit works properly.It does, however, have a terrible rejection rate; something in the range of 10:1 reject to product water. This is much to high for city water, even on a bad day.This is probably because the city water pressure is too low, but there is no way to tell.There is no information in the instruction regarding pressure requirements.
Part of the problem with the unit is the instuctions are nearly worthless.They look like a third generation copy spit out of a copier in need of a good cleaning.There is nothing in the instructions about the minimum or maximum operating pressure, nothing about recovery rate, no troubleshooting guidance and the print is blurry.Unless you have a good idea what your doing already, you might want to try somebody else's product.
The good news is that the unit is truely portable and requires no power whatsoever to operate.You could probably use it on a camping trip if you had a hand pump or some other way to develope enough pressure to operate the unit.It is compact, but the tubing array just hangs loose with no provisions for storage or detaching, making it somewhat difficult to store neatly.Overall, not a very well thought out product, and more expensive than it should be.

While constructing my 35' waterfall feature, a friend told me the usefullness of using this filter at the top of the falls.I am very glad that I followed the advice.I selected this particular filter because I was using a 5500 gph pump and with the vertical height and length needed it would be spilling around 3800+ GPH.This filter handles this large water capacity excellent.The filter only comes with one filter pad and I recommend using two.I have found that this keeps your water cleaner and clearer.I believe Atlantic water garders filterfalls are top notch products and I would recommend the use of them in your water feature.You, your fish and plants will be happy with the results the filter provides.
