Geekpure 3 STAGE Portable Aquarium Reverse Osmosis RO Drinking Water Filter System-100 GPD

This little powerhouse is a magnificent marvel of technology. For less than 60 dollars, this system can not be beat!Comes mostly assembled. All I had to do was insert the RO membrane into the cylinder and connect water input. This does NOT come with a garden hose adapter, so I purchased one separately that was listed in the "Frequently bought together" list.We have terrible well water that comes out RED sometimes from all the clay deposits. My EC meter measures 650ppms on our raw well water (500ppm scale). The water produced from the clean water line of this filter reads 0PPM! I have had this unit for a couple weeks now and it has produced over 200 gallons of pure, clean, great tasting water for me and my plants!If you are a gardener, this RO system is a MUST!If you are a clean water fanatic, this system is a MUST!Great tasting water! SO happy with this purchase! The replacement filters are only 37 dollars for the whole set, which is VERY affordable! A friend of mine has had this RO system for 2 years and has never even replaced his filters, and his still works great!It may not be the fastest RO system on the market but if price is an issue, BUY THIS UNIT!! I suggest buying a tank or 5 gallon water jugs to store the clean water in, as it takes about 5 minutes to get a full 16 oz glass of water. Also, does not require crazy high water pressure. I'd say our water pressure is no more than the average household water pressure and the system still performs just fine.I am telling ALL of my friends about this great filter system! I wish I had found this a long time ago! Thank you OSMOPUR for making a great, affordable RO system! Finally, EVERYONE can afford clean water!

So far I'm impressed, this is a good quality RO filter. I have had no leaks, the tubes came already connected, so it was pretty much plug and play after you mount it and add the membrane. It came with quite a few extra tools for other types of installation. I was a little on the fence, since I hadn't heard of this brand and purchased 2 aquatic life RO buddies in the past. My first impression is it is just as good if not better value. I was able to make about 4 gallon RO water in about 35 minutes and the waste water was about 5 gallon (see pic). A 4/5 ratio of RO to waste water seems really good to start. I got 12 ppm (parts per million) on my TDS (total dissolved solids) meter. I usually get 18-20 ppm when buying water from outside store machines and my tap water is 425 ppm. If you want 0 ppm you'll need the 4th stage (DI resin).Lastly, I bought a separate angle stop adapter valve sized 3/8 UNEF X 3/8 UNEF X 1/4" at Home Depot to connect it under the bathroom sink, check your faucet hose connector size, but that worked for me. Hope this helps someone!

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.
