Geekpure 4 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.

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)

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!

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.

I recently installed this water purification system, and it has exceeded all my expectations. After extensive research, I chose this system to address the quality of my well water, which contains significant sediment. To ensure the best results, I pre-filter my water at the pump using a series of sediment filters before it reaches the Geekpure purification system at my sink.The results are impressive. When I tested the purified water, it consistently showed 000 ppm, indicating absolutely no dissolved solids. The water is crystal clear, with no detectable flavors or odors. It's refreshing to finally have pure, clean water straight from the tap.The system is easy to install and maintain, and its performance has been consistently reliable. This purification system has significantly improved our water quality to the point I do not need to purchase gallons of purified water from the store, and I highly recommend it to anyone dealing with well water.

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

Works great, reasonable price, easily produced 8 gallons on first run / < 8 hours. Note if you use the included saddle valve, on our heavy copper supply lines it wouldn't self-pierce, I needed to open the hole with a 1/16" drill bit. Once flow was established @ our 40 lb house pressure input was off and running. I was buying grocery store distilled water for $2.00 a gallon, this will easily pay for itself in < 3 months. Installed on running in < 30 minutes as a stand-alone system. The only minor negative is the "loose" structure which could be rectified by mounting on a board.

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.
