this is the second unite i bought, and just like the first one, the unite arrived with two cracked canisters.(Customer Service replaced them)the disturbing part is with the first unite one of the canisters did not crack until the pressure built up in the unite by the auto top off system . In my opinion this is a poorly made piece of equipment .

one star only because the setup was pretty simple, but as soon as i got everything hooked up and turned the water on one of the filter canisters began to spray water out. i looked and noticed the o-ring kinked, so i applied some teflon putty and it did the trick. water was flowing, pressure was holding; so after about 3 hours of checking i was happy and went to sleep. next morning i woke up and went to check on the ro system and walked into a stream of water flowing from another filter canister...i had enough and replaced with another system. waiting for the new system to arrive. fingers crossed

I like making my own water and this system appears to do a good job. The two things I dislike are the speed at which it produces the tank water which is quite slow (I get two 5gallon canisters of waste water to one 5gallon canister of tank water, which seems like quite a waste. So, I purchased a water cooler so that I can stop wasting so much water). Second is that the instructions were not very clear, but I contacted customer support and they were awesome, providing me with answers via links I could watch or via email. Thanks

Great Water System.....! Started off little rocky because when I got the system a part was broken in shipping ...but once I called customer care with no questions asked sent me another system overnite and I got it within 48hrs. I had no problems hooking up the Captive Purity water system....instructions were simple and easy to use.....I would recommend the system to family and friends

My recent R.O. filter purchase has been a positive experience, I am very satisfied with the captive purity brand. The water quality it produces is above average and very efficient in production time. For the price it is so far the best filter I've purchased to date out of four over 12 years. Thankyou again!

It was very easy to get it working. I would guess that the product/waste ratio is 5:1. I was going to install it under my tank for topoff where I have an existing water supply and drain. But after seeing how much waste water is produced, I left the unit unattached and drain the waste water into my pool. Or I find other uses for it.
My incoming TDS is over 400, and it comes out at 000. I have only had the unit for a few weeks, so I don't know how long the filters will last.

Good unit from what I can see so far. Simple to install and the canisters are very solid. My only complaint is that the bracket the canisters attach to feels flimsy compared to the rest of the system.

I purchased a R/O machine from my LFS and it didnt work very well. I tested the finish product water and found that it was as dirty as the water going in. I took it back and they gave me a new one. It didnt work either. I ordered the captive purity RO/DI from Marine Depot and found it to be perfect. Easy setup and clean water production. Marine Depot even answered all my questions on setting up a float valve to my unit. I recommend this product for anyone who wants pristine water in there tank.
