Geekpure 4 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filtration System 100 GPD - with DI Filter TDS Close to 0 ppm

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!

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.

Easy to setup. No issues what so ever. Will make mention that high ppm water will greatly effect the di filter's lifespan. So those with city water be prepared to replace filters much more often. Filters my 400 ppm tap water to zero. I personally seem to only get 25-35 gallon before the ppm starts coming back up. But as aforementioned I blame that on the hard water content of my tap water.

It’s pretty straightforward, even without the poorly articulated directions, but a warning in the directions to check the gasket in the main filter would’ve saved me here..I spent well over an hour getting this thing installed only to have it not work. When I tightened down the main filter, the gasket wasnt seated correctly. It leaked carbon everywhere.. I’m guessing it clogged the filter because I’m getting no water out of it…Their warranty doesn’t cover filters so I’m just out…Pretty disappointed to say the least.

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

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)

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.

I got this on Cyber Monday for less than the cost of replacing the cartridges on my old 4 stage RODI. Comes with tons of extras for plumbing which was nice though I had to get my own 3/8"x3/8"x1/4" stop as I was stacking it on top of another tee to my icemaker on the cold water line for my kitchen sink. Came with all the hardware needed to splice the drain line into the sink drain. So much better than carrying a bunch of filters around and attaching them to faucets. Carrying 5g buckets of water to my tank is bad enough and this makes the job of making my supply of top off water for my ato and water needed for changes WAY easier. All the filters came connected which made installation much faster. Very happy and so is my reef tank!
