Not Bad

Best bang for your buck. So far I'm very impressed. I added 2 extra stages of DI resin for my aquarium and I couldn't be happier. Filled up 5 gallons in about 13 minutes.

Mar (Las Vegas, Nevada, United States)

Works pretty well, taste ok. I wish the water pressure was a little better. I kind of expected it since it's tankless.

What seemed like a swift installation, took longer than expected. At first my husband thought, maybe the containers had an issue because it kept leaking. The rubber ring kept coming off. Apparently, we needed to be a little more gentle on closing the containers.

Product exceeds expectations

I bought this product for my boat that is in a Slip in Salt Water. Specifically, I attached the input 3/8 supply to a Sharkbite to Hose bib adapter with City water.

I flushed my pre filters for 15 minutes and then connected the RO Membrane and post taste filter. I let that run for 20 minutes and verified that there were no leaks - completely dry. I then placed into my dock box and added a NEMA-15 converter plug for the pump and all was set. I egress the waste water through a small hole drilled in the bottom of the box. I purchased 40 feet of 1/4 tubing to connect to the output of the R/O unit and then ran that to the Deck fill point on my boat. I let the unit run into a sample cup and found the following :

On my Boat I have 120 gallons of Fresh water tank storage. I use a pre-filter which is a 30 micro spun Poly filter and that goes to the water heater and house cold supply. For Drinking I have a First Need 0.4micron filter setup which delivers biologically safe drinking water but does not impact the TDS value at all. It will give me biologically pure salt water if I hooked it up to the ocean.

Flow Rate 0.69oz/second or 19.4Gph
Hose TDS On Input 648PPM which amazingly is "potable" Ventura CA City water.
TDS on Output measured from my boat sink faucet or drinking water filter (the same TDS). 38PPM
Expensive Land RO Water purchased from a Vending machine was 20PPM.

Unit runs quietly and all I do is turn on the hose and plug in the pump and I have fresh water filling up my water tanks.

One request would be a Y valve for allowing the user to direct the pre-filter (3) output into a user-supplied 3/8 tube for the specific purpose of flushing the 3 pre-filters due to a change in them. I don't think that it's a good idea to be subjecting the R/O filter to this stream of debris, even in the recommended bypass mode.

Another request is to offer this Product without the supplied tall Faucet which I have no need for on a boat.

I would like to be able to update this Review in Six months and hopefully I still have nothing but good things to say about it.

Best filter system I ever owned

By far the best system I have ever had to filter my water. Best tasting water by far! Very pleased with the results.

William (Berkley, Michigan, United States)
Almost perfect

Non-standard install. Had to place in basement right under sink area due to space considerations. Only trouble was connector from line to faucet. It leaked. Followed all suggestions but still leaked. Replaced with “SharkBite” brand and no problems. Works fine. Will update if any other failures. Nice product.

Greatr Expectations

As yet, we have not installed this unit in the restaurant for which we purchased it, so we haven’t built any testimonials for it. We believe it will be installed soon, though. And we’re very sure it will perform wonderfully and its testimony will cause us to be marketing even more of these units.

Robert Kull (Cincinnati, Ohio, United States)
Tankless R/O system

Customer is very happy so far with this unit. This unit makes purified water on demand . If you need 10 gallons of water , you turn on the faucet let run until it’s made it instead of wanting 2 days to get it from a unit with a small tank.


The product is great but water flow was not as great as it sounded in the description.


Order was poorly packaged with pieces missing. Misthreaded adapter was useless. Had to return.
