Geekpure4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm

Great ro unit, flow rate and recovery higher than more expensive systems, works better with a tank. I have 2 units now! One in my home and one in my rv.Needs on/off control as it runs all the time without shutoff. I used a 13 volt solenoid in rv and pressure regulator in home.

Makes mineral-free water which I use in my CPAP humidifier. I check the product water with a Total Dissolved Solids meter and it's high quality.

Great but can’t find replacement filters

Only buy if you want to spend an hour filling a cup. I contacted support they tried putting the problem on me it constantly runs when the faucet is on or off from the flush side wasting tons of water and has 10 x’s the pressure the output side does. Asked them to help me find a solution and why their video shows it comes with a tank and yet it doesn’t. Their support was absolutely trash in my book. Want 5 gallons of water prepare to wait all day long to get it. Want a glass 45 minutes and there is more than enough pressure to make it more than a burping output. Had culligan come look at it and they said quote the worst system they ever seen yet and explained the only way to fix it would be to put a pressure pickup pump on the output and about a 14 gallon holding pressure tank.Run don’t walk to another company cant get my money back that i wasted and cant get resolved without dropping another 2-300 bucks just for parts on here.

Holiday sale had these marked cheaper than replacing the filters so I ordered a few. This is a very basic system to give you a slow flow of RO/DI water. You need a valve at the Inlet to shut it off when you are not drawing RO/DI water. Adding a float to the outlet will help prevent spillage, but will not close the drain/waste water outlet, you will also need the 4 port auto drain shut-off if you want such features or to add a faucet. Great value when you don't need all the extra features, even better with the discount I received, still pretty good if you also want to add separate upgrades, as the all inclusive kits easily cost double but only add a faucet, storage tank and auto drain shut-off. Some customers need to store much more water for selling brewed beverages, making included 2 gallon tanks surplus inventory and wasted money.FYI don't drink plain Deionized water, with replace the Deionize filter with a inline polishing filter (carbon) for low TDS drinking/cooking water, make sure to get adequate minerals from your diet or add a mineralizing stage (such as alkaline) *designed for drinking water* as the final stage with or without the Deionize stage.I am a big time believer that our hard local tap water gives kidney stones so I opt for low TDS water and spring water. Grew up plumbing, i can taste and smell chlorine and limestone in tap water, seen limestone, fluoride and calcium in toilets, water heaters, dishwashers, sinks, showers/tubs, casted over long neglected leaks... Some people say low TDS water is unhealthy, you can't convince me my tap water is healthy, MAYBE safe, but not healthy. The extra 530 PPM of nasty stuff I filter out scares me way less than the low 20ppm reading of my RO "thirsty water" (but not deionized water, 0 PPM is indeed too low for drinking water)

Does the job well but very very slowly. Otherwise I’m happy with it

Works great! I use it to filter water for humidifiers and non-potable applications and it is working excellently. The only gripe I have is that the flow rate is extremely slow. The filters tubing used is cheap and plenty is included, making connecting and installing this kit a breeze!

Received this product awhile ago. Never installed a RODI unit prior and just entered the saltwater community. I finally got this product installed last night after many tries and fails. The instructions are more complex then need to be. I had to YouTube a video in order to install. If I was this company I would invest in making an installation video for the Amazon product description as well as maybe dumb down the instructions. Also it would be easier if the seller included a faucet head adapter instead of having to become a plumber and installing under the sink. I will say this product works, I tested the parameters and everything was great. So yeah just the installation process.
