Very professional packaging to insure nothing was damaged. The user guide and installation was very informative. It took me 48 minutes to completely install. It came with a little bag labeled extra parts which was handy because I overtightened one of the fittings and cracked it.I live in a tiny apt. Everything fit compactly under my sink with room to spare. I can easily Uninstall this unit and take it with me if I chose to move.Before this unit was installed my TDS reading was just under 400 ppm with slightly orangish tinted water. Now , after the install my TDS is 52 ppm with crystal clear water. I suppose that's the minerals added from the filter.The water is definitely oxygenated you can physically see it. The taste is smooth and pure, better than any water I have ever purchased. The unit will more than pay for itself quickly and I no longer have to lug and refill those heavy 5 gallon jugs around.I filled my ice trays with this system and the ice cubes were crystal clear see through.I am very happy with this purchase and anybody can install this themselves the instructions are in color with detailed pics for every step. They also privide videos on their website & you-tube.I highly recommend this company.

Overall very please with this product's quality and function. For decades used water from refrigerator filter, but found out it didn't screen sodium (which contributes to artery hardening and high blood pressure) so sought alternative which only is Reverse Osmosis, as we use a salt water softener. The instructions are fairly simple and most diagrams are clear and color coded tubes so makes for ease but not 100% error-free install as some dependency on text interpretation did require a tad of rework. Plus there is 'just enough' filter tubing for a basic, very near to water supply and counter install so if you have an unusual configuration may need to buy additional hose as my message to the manufacturer asking for more was ignored/unfilled. This unit is fairly tall, so I had to rearrange the filters atop and tie them together with nylon ties to fit under the sink - beware!!!!! especially if you have a deep sink well as cabinet height clearnace could be restricted. There's not much options for the filter module relocation so if you can move them around to be overall lower height well it's a product return for you. This aspect disappointed me and took a bit of ingenuity to work around that most customers would not want to contend with. As for the product install, did have some human error with tubing install so had a leak or two but once found easy to remedy - but again, if tubes supplied are too short and you stress out the plug-in connections - oops water water everywhere. I also bought the 3-year (?) filters product so I don't have to worry too much about manufacturery supply. I bought a water test kist and ALL the readings were in compliance and happy to say most (but I think one) were ZERO reading. BTW, we are on well water, and mentioned we use a salt water softener and a whole house inline sediment filter. The manufacturer did reply about the drainage tube install location/alternative as you do need to drill a hole into an existing drain pipe AT THE PROPER LOCATION which is probably the most stressful aspect aboutg the install. Tapping into the existing water supply using an adapter (rather than old fashioned screw-in puncture tap) was convenient and trouble free. Would buy again, but probably buy some extra tubing for install convenience.

I didn’t post a review when I first bought it, I’ve waited a year and here are my thoughts1. Filtration: does everything it says it does and does it well. This was a gift to my in laws and they didn’t change any filter for a year. DO NOT FORGET TO CHANGE THE FILTERS. See my pictures.2. Taste: like the fountain of youth. The water is almost sweet and tastes better than purified water.3. Ease of set up: not the easiest, but also not too difficult if you’re mildly competent. The documentation they give you is very extensive. Read it front to back before you even start unwrapping everything else. The hoses are color coded so you’d have to be thick in the head to mess that part up. The only part that may give you trouble is drilling into your drain pipe and counter top of you do not already have a hole for a faucet.4. Changing filters: easy. Took me less than an hour.5. Noise: can make noise due to air on first set up but it goes away after flushing.6. UV bulb. It gets hot, like others have said. Honestly, it’s my only regret. We’re on city water and frankly, unless you have a very specific need for it, you probably don’t need it. Also, unless you’re an electrician or have any handyman skills, you have to find a way to route power to the bulb that doesn’t require unplugging your garbage disposal. I wish there was an easier solution but it is what it is. What’s great is that you can buy the one without the UV, and if you find yourself needing it, you can buy it separately and add it on.7. Size: Fits perfectly under the sink with plenty of room to spare. Make sure you layout the filter and measure the hoses before you start just cutting and connecting8. Leaks: no faulty fittings or leaks. Any leaks I did find were my fault for not connecting the hose properly or wrapping enough plumbers tape. I caught it on initial set up and it hasn’t leaked at all in the past year. Even still, it has a leak detection fail safe which I tested and works perfectly.Conclusion: 9.5/10, definitely recommend. I bought 2 and both have held up really well. You probably don’t need the UV, but to each their own.

El agua que sale del sistema es de muy buena calidad pero el gasto de agua que hace el equipo es excesivo por cada litro purificado gasta de 3 a 4 litros que se van directamente al desagüe yo pude medir el gasto de agua porque no lo conecte directamente al desagüe sino a un contenedor de agua. La verdad es que no es un equipo que se deba de utilizar en estos tiempos donde el cuidado del agua es esencial, los sistema de osmosis inversa a nivel industrial tienen una eficiencia del 70%, esto es, 70 purificado y 30% de desperdicio y para este equipo es al revés de un 25 a 30% purificado y 70 a 75% de desperdicio.

Excelente producto. Lo use como reemplazo a un purificador viejo que solo hacía filtrado y cloración. Este es muy fácil de instalar (quien invento las conexiones rápidas es un genio). Es modular y fácilmente se identifica donde va casa pieza, todo va por colores. Excelente sabor del agua. Lo único malo es que el sistema de RO desperdicia mucha agua (mas o menos produce 5 litros de rechazo por 1 litro purificado), pero esto es un problema común con todos los sistemas de RO y es parte del diseño. En mi caso, en vez de drenarlo al drenaje (como lo indica el manual) lo dirigí a un contenedor afuera para usar esa agua de rechazo para el trapeador y el riego del jardín.

excelente producto de filtrado ya que cada ves el agua que llega a nuestras casas cada ves esta mas contaminado y sucia

This is the 11-stage RO filter setup with UV sterilization and alkaline remineralization stages. Everything is pre-packaged in a way to ease installation but kind of a pain if you're planning to add a permeate pump or branch out the lines before/after the remineralization stage (to get regular RO water for things like a coffee maker or other cooking needs while getting mineralized water for drinking).Overall, while it's assembled rather well, it's still quite bulky. I was surprised that the 4-gal tank isn't the most imposing component. The 3-stage primary filters at the bottom of the kit dominate the space. The RO, UV, ALK, and PAC units mounted horizontally on top are quite a bit smaller. That said, the entire kit will fit in the cabinet under a common double sink under the one WITHOUT a garbage disposal. If you have a garbage disposal under one sink, space will be tight (at best) on that side so plan to install on the opposite side.I'm pretty bad at plumbing but installation was actually rather easy thanks to most of the work already being done with the 1/4" tubing and quick-connect fittings. It took me MAYBE 90 minutes start-to-finish (plus the fill/flush process afterwards). The hardest part was connecting the tubing to the included faucet which, in hindsight I could have made easier by fishing the tube up through the retention nut, the countertop, the top washer then onto the faucet stem before securing the faucet to the countertop. Instead of the included drain "saddle" I opted for a "Y" tube that fits inline with my dishwasher drain into my garbage disposal - no cutting required.I opted to add a permeate pump, as well. That requires some re-routing of some of the pre-installed tubes but isn't all that complicated once you understand how it works and where each tube comes from and goes to. Overall, that reduces the wastewater by a significant amount (sorry - I don't have before/after stats). It also reduces the total fill time from 2-3 hours to about 35 minutes and makes flushing/priming new filters a LOT quicker.I did have one faulty connection in the system that needed to be fixed and it was one of the factory-installed ones. The "T" that feeds the PAC (the final filter) and the tank wasn't seated correctly and leaked straight away. I simply removed the tube, re-cut the end, and reinstalled it - job done! No leaks of any kind after that.I also opted to NOT physically mount the unit inside the cabinet. I know filter changes are going to be a pain so I simply left it sitting on the bottom of the cabinet with enough slack in the tubes to remove it to the floor in front of the cabinet. From there, I can disconnect all my tubes that go back under the sink and re-work the filters up on the counter or in the sink, as needed.The municipal water supply where I live is actually already pretty good. I just wanted better tasting water. We've used a drip-type filter for a few years and it does an okay job but I'm still finding a slightly "off" taste occasionally. This RO system TOTALLY removes any hint of weird odors/tastes and is better than many bottled waters I've had. Fiji is as close as it gets.Get yourself a glass pitcher, fill it regularly, and keep it chilled in the fridge. OR get a "T" tap off the feed to the RO faucet and feed it into your in-fridge water supply for the best ice and water you'll ever taste.

Deberian aclarar que aunque tengas bomba presurizadora en tu casa no es suficiente para que el sistema funcione. Tuve que comprar una booster pump y son caras.

El agua que produce es de excelente calidad y además es alcalina, con muy buen sabor y sin olor. Es un excelente sistema a buen precio disponible a meses sin intereses. El tanque de almacenamiento es de 10 litros y la membrana RO es de 378 Litros por día (100 GPD) que es la más duradera. La lámpara UV se alimenta a 110V. Incluye sensor de fugas, conector de 1/2" con derivación y llave de paso a 1/4" y mangueras con código de colores para facilitar la instalación además de un buen manual ilustrado. Es el único sistema que incluye etapa de Luz Ultravioleta y etapa alcalina en México. El agua alcalina no se recomienda para máquinas de hielo, por lo que se conectan antes de la etapa alcalina. Sin embargo se requiere experiencia en la instalación. Antes de comprar recomiendo que se documenten, hay excelentes videos en la red (fresh water systems) debido a que los sistemas de ósmosis inversa en México requieren de una bomba auxiliar y un medidor de presión para que operen eficaz y eficientemente. Con la bomba la producción de agua genera 1 litro cada 10 segundos y llena el tanque de almacenamiento en una hora con 5 litros de agua de rechazo a una presión de entrada de 80 psi. De otra forma una baja presión sí permitirá la producción de agua pero lo hará de forma muy lenta, 1 litro por cada 5 minutos, y el tanque de almacenamiento no funcionará, además de que el agua de rechazo se incrementa a un litro de rechazo por litro producido. Si no quieren ahondar en detalles de instalación recomiendo un sistema prefabricado que incluya bomba y agregar las etapas que requieran, la diferencia es que cuesta más y no es tan eficiente. Entrando en detalles de instalación, el agua de rechazo la almaceno y uso para limpieza general. La bomba se coloca antes de la membrana RO y en mi caso requiere sensores de alta y baja presión para evitar que se queme y normalmente se incluyen con la bomba. El sensor de baja presión se coloca a la entrada de la bomba y el de alta presión a la entrada del tanque. El medidor de presión se coloca a la entrada de la membrana RO y debe marcar 80 psi o menos cuando funciona la bomba para no dañar la membrana. La lámpara de luz ultravioleta debería apagarse cuando no se produzca agua o el agua saldrá muy caliente. En la parte eléctrica se requiere cable 18 AWG para conectar los sensores a la bomba (en serie), agregué un relé controlado por la alimentación de la bomba que corta la alimentación de la lámpara cuando la bomba no funciona. El kit de bomba (geekpure) con sensores, terminales y adaptador de voltaje, y el medidor de presión los conseguí en AMZ EU. El relé y cable 18 AWG para la conexión de la bomba en una tienda de electrónica local. En los videos se habla de una bomba de permeado para hacer más eficiente el sistema, yo no la ocupe, sólo ajusté la presión de salida del agua de desecho con una llave de paso.

rapido y de excelente calidad, sabor inigualable

No tan fácil de instalar como dice la publicidad, es laborioso pero no complicado. En mi caso no hubo suficiente presión de agua en la tubería de mi casa, de tal forma que tuve que comprar una bomba especial para sistemas de ósmosis inversa (a otra compañía pues el fabricante ya no las vende) asi como un switch de alta presión que automatiza el funcionamiento de la bomba.El sabor del agua es completamente diferente y supera cualquier agua embotellada del mercado. La tranquilidad de no tener que beber agua que haya venido envasada en una botella de plástico y los tóxicos que liberan al agua.Casi no puedo creer que ya no tenemos el permanente y engorroso ritual de comprar garrafones de agua.La empresa es muy amable y servicial si tienes preguntas durante el proceso de instalación y después.muy contento con este producto

Excelente producto, por fin tengo un sistema de filtración de agua al100% comprobado.el que tenia anteriormente no eliminaba completamente el sarro y cloro del agua, este ya lo comprobé y lo elimina completamente, lo recomiendo ampliamente.

I really would love to give this 5 stars however I’m a little disappointed with the setup startup process. It takes 5 full tanks of water to fully clean out the system and the water is suitable for drinking. We are on a well so this was a waste of water AND electricity to run the well pump as it took a full day to complete the process. I think they (express water) should improve on this!The good side is that it was easy to install. I did it myself I a couple hours. Hardest part was getting the screws for the mounts in the right place. Another thing they could improve one is including a diagram of the screw holes you can stick to the side of the cabinet then make your holes. Now I have about 6 unwanted holes! And I’m not super strong and it’s an awkward position under the sink...The install of the tubes is tricky as you absolutely need to make sure they go in all the way into the fittings or you will have leaks at startup. You can feel when the tube is in place. You’ll know it when you feel it. These are 1/4” tubes so if you’re replacing a system with 3/8” existing you’ll need extra fittings, my husband picked me up a few at Home Depot. I kept my incoming line as it already had a shut off valve and I kept my out going as it already had a T for the ice maker and I liked my current faucet rather then the cheap looking faucet they sent with they system. This could also be improved upon.All together great system, water tastes great. Could use some improvements but that doesn’t effect the overall usage just would make things nicer.
