Geekpure3 Stage Portable Aquarium Reverse Osmosis RO Drinking Water Filter System-100 GPD

I have a 32 gallon barbecue I use this to make up the water I have a total TDS of zero when it starts I am at a TDS of 250 so works really good thank you

greatt been usuing it awhile now and works like a charm

I’ve installed 4 or 5 R/O systems in places I’ve lived to get bottled-water quality from the tap. I prefer to get rid of as much chlorine, lead, and fluoride as possible. Good clean taste - or lack of taste - is also important.I chose this unit to produce clean drinking water in my travel trailer as there really isn’t room for a pressure tank like most R/O systems.The unit works well and at ~50 psi produces R/O filtered washer at a pretty high rate. Easily several gallons an hour. The unit is compact and I bundle it up and store it away after filling all of my jugs and bottles. Without this unit, I’d be going through several 24 or 36 packs of half-liter plastic bottles a week. That’s just too much waste. I refill the better-quality bottles and save the plastic/planet.Two minor downsides that I noticed:Description says that unless you specify otherwise, you’ll receive a garden hose thread adapter. That’s not what was in the package. My kit came with a whole standard “under sink” hardware kit. Self-piercing valve, shut-off valve adapter for typical supply lines, and the clap/tap that fits your drain line for the waste water tubing. There was done other valve in there that I couldn’t quite figure out. At any rate, if you want to hook this up to a hose bibb, you’ll need a few fittings.I also noticed that the tubing arrangement as shipped routes the water through a carbon filter -before- the R/O membrane. All of the other systems I’ve installed touted the water through the carbon filter at the very last stage. Though this may be due to this system not having a tank, I would think it’s a bit of a waste to be using up the carbon filter’s life filtering water that’s going to go down the drain. I may read-route the tubing to sent the water through the carbon filter last.At any rate, an efficient and affordable solution to the need for high-quality filtered water. You may just need to run to the local hardware store for a few stray bits and pieces.

I got this because of the many high ratings, and advertised ease of use. I had purchased a distiller a while back, and the output was way too slow for our needs. He high cost of RO units had kept us from trying one, but then I found this little guy. It arrived nearly fully assembled - I just needed to put in the membrane filter part. I went to 3 plumbing supply stores and 2 hardware stores to find a valve that fit the tubing, and that also had a shut off. (Reviews had said not to trust the fittings). 2 of the plumbing supply stores looked at the pictured diverter valve and told me “I’ve never seen anything like that in my life”. They also said there was no way to connect this unit to my sink. Finally, my local hardware store saved the day and took the time to help me. I just measured our water from the faucet and it was 503 ppm. The filter included on our refrigerator puts out water at 408 ppm. The RO filter setup is currently running, and “flushing”. After 10 minutes, I checked the water from the red and blue hoses out of curiosity. The red hose is supposed to be concentrated impurities, and the blue hose is supposed to be filtered water. My red hose is putting out water at 750 ppm, and the blue hose is reading 9. Yep, this filter is taking my water from over 500 ppm, and giving me water with a ppm in the single digits. I’m impressed with the quality so far, for the cost. The only issue I can see is that the filters might get used up quickly, and they seem to be sold in packs, for a premium. As of now, 5 starts though. Works as advertised, no leaks.

If you are going to use this you better put a valve on the intake side of the system so that you can shut it off manually when your reservoir is full. Otherwise the waste water never stops flowing and will cost you a fortune in your water bill. For reference I have a 25 gallon reservoir with a float valve to stop the RO water from continuing to fill it. I ran the waste water directly to my sump pit. If I had followed the manufacturer's instructions amd ran the waste water into existing plumbing I probably would not have noticed it never shutting off until I got my bill.

I'm super happy with this purchase! I was very intimidated by the idea of installing it and, although it was pretty difficult to find a valve that would fit, once I figured it out, the installation went smoothly. The valve it comes with didn't work with my pipes and I had no idea what to search to find a replacement. Luckily, Reddit saved me and now I can tell you. I got a "Feed Water Adapter Angle Stop Adapter Valve 3/8 X 3/8 X 1/4 Inch Compression Tee Stop Valve Fitting Water Line Splitter Valve Adapter For Reverse Osmosis Refrigerator Ice Maker". I found it on amazon as well and it's been working great. I used a Teflon tape on the connections and there is no dripping/leaking. Water fills decently fast too

No leaks, survived two moves, lowered TDS to <3 ppm, CHEAP, excellent, excellent product. The instructions are really clear, I just followed them. When installing, you must ensure you fit the tubes correctly, and that the unit is standing upright. Please read the instructions. Can't remember if I'm using the included diverter or one I had. Even if you need to buy a diverter, just buy it, you're saving hundreds of dollars buying this unit.

The materials seem cheap including the plastic. I’ve been buying RO filters for years with zero problems. This one won’t test below 33 PPM. They tried to tell me that’s normal which is funny. I have one that’s probably 3 years old that never rests under 10 PPM.
