EXPRESS WATER UV Reverse Osmosis Water Filtration System – 11 Stage UV Water Filter with Faucet and Tank – Under Sink Water Filter with Alkaline Filter for added Essential Minerals 100 GDP

this filter is pretty amazing. It is so good at removing hard water that the water boiler i use does not need to be cleaned even after months of use (no sediments at the bottom). The water has no chlorine taste. The PH is higher than tap water (I have the meter) at 8-8.5PH and the dissolved solids is very low (also have a meter) compared to bottled water and tap water. Because it has an internal bladder that hold i believe 1 gallon of water, you can run out of tap water and still able to drink water from the reservoir. It is very well designed with great quality materials. The UV light kills any remaining germs/bacterias/virus in the water. This is an investment in your health.

Easy to install and came with very thorough instructions. The water tastes great and the flow is as expected. The main filter housings are a bit difficult to thread all the way on and it took some force to get them to thread all the way to the point of compressing the orings and not leaking at all. I like That there is a leak prevention/emergency valve that cuts off the water to the unit if water is pooling under the sink.

Have it for almost a year, no problem. The water quality has improved dramatically, have to use rain water.

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.

The media could not be loaded. First Thing First:I love the idea of sterilizing the water through the UV Light. that's why I got the 11-stage system.But this UV Filter stage needs a small improvement. I am not an engineer but I think its something very easy to do it... you can check my concern in my reviewOn the other hand, This thing is BIG. the whole filter system...Under a regular sink with a food garbage dispenser, it would not fit on the same side of the cabinet's wall with the water storage tank. Because of the waste food dispenser under the sink, the water tank will not fit on that side. However, not a problem because of so many filters that need to be changed regularly, is better to be face out for easy access. But I had to make a small modification to my cabinet to hang up the filter system...After connecting all the tubes in the connectors I had absolutely No Leak.Now lets talk about System performance with real numbers for home use:Before my first glass of water drinking from the system I flushed the tank as the company said more than 4 times. Actually I flushed it out 7 tanks.Before everything I measured the pressure in the empty tank and I got 8 PSIin the 2nd tank flushed out I got 2.48 gallons until the tank got empty.3rd tank 2.72 gallos4th tank 2.77 gallonsThey said the tank is 3.2 gallons of water capacity. and if you don't have that amount of water you should to stretch the tank's bladder. As I did.After I stretched the tank's bladder I got for5th tank 2.98 gallons of water6th tank pretty much the same but less.To empty the water storage tank I got these numbers:For the 1st gallon you need 1- 1/4 mins for the 2nd gallon you need about 2 mins then the pressure gets lower and lower ... However to empty the whole tank 2.95 gallons of water it takes about 5-1/2 minsTo fill up full tank till the system auto shuts off :I have 65 psi water pressure in the system which is great .For that pressure, the System needs 1H 15 mins - 1 H -30 mins to fill up the storage water tankDoing a short easy math, in 5-6 hours the system can provide about 12 gallons of waterIn 24 hours 48 -50 gallons /dayIn the technical specification, they said the production Rate is 50-100 Gallon/day. So the lower number is the right number.BUT my big con is the efficiency. I didn't make any measurements yet, but I can say that for a gallon of drinking filtered water, you going to waste on the sewer probably more than 4 gallonsPROBLEMS:1. I found slow dripping water drops in one of the UV Elbows that was preinstalled. I unscrewed that elbow, added new teflon tape, and the problem was fixed. No leak at all in any points or any connectors. Sounds pretty straightforward but is not like that easy after all the system was water-pressurised. It takes time to shut off the system and flush water from the whole system and the tank and even so you still have some water in the filters.2. I wanted to have a pressure gauge that I got separately. There was another problem because after I tied up the Ro Membrane Filter Cap the angle elbow from it was not face up as in the picture and it was about 45 degrees back and the gauge didn't have space anymore. Needed a 90-angle elbow to be able to fit that gauge...Happy with that gauge pressure. Anytime you can check exactly what water pressure you have in a system. That thing should be in any kit.I have no idea how efficient is that UV Lamp but for sure you need to invest about $60 or more to make it right.1. They advise you to have a surge protector for your UV light tube if it will be plugged in the same outlet with your Garbage Disposal. That is about $15https://a.co/d/5cvexbB2.In most cases you have a socket under the sink where you feed the waste disposal that has a switch in the wall. To power UV light all the time you will have to buy another outlet with air switch for disposal. That is about $ 35.https://a.co/d/5ftWD2h3. To install that button you need to make a whole in your sink or countertop you need a Hole Saw Drill Bit for Hard Metal which is about $20https://a.co/d/ftygO8ENow, about the Sanitizer UV Light Filter.THIS SHOULD and MUST BE IMPROVED !!!Such a shame that this UV bulb is always on and they did not design an electrovalve or something working in tandem with the System's "Automatic Shutoff Valve" to turn on the UV light Bulb ONLY when the System is running and filtering water.Many people complain that the UV House is getting HOT. Of course, is getting hot as long as the water is not running through the UV sterilizer house.No reason for that UV bulb to stay on as long as the tank is full and no water is circulating through the system.If the UV light bulb will stay on only when the System produces water the life of the UV Bulb will be way much longer. Depends on how much water you produce. For a small family 2 adults and a kid, you probably are going to use 1 - gallon /day so, the whole tank is good for 2-3 days. Imagine that, to fill full the whole storage water tank ( let's say 3 gallons ) you need 1H 30 MIN... So the UV bulb SHOULD stay on for only 1h 30 min in 3 days, ONLY when the system filters water. But... the bulb is actually always on that means 72HOURS...So 55 times more energy wasted and 55 times shorter life for UV Light BULB2nd Problem.Even Having just overnight water stuck in the UV sterilizer housing with the UV Bulb on you going to have almost boiling water in there. and when the System starts running filtering water, that hot water it would be pushed into the storage water tank bladder which is nothing else than a rubber tire inner tube "butyl rubber" .I didn't do any research about the interaction between the polymers in rubber with hot water. If they leach more toxins with hot water than the cold water... Lucky us... after that water sitting in that rubber inner tube for 3 days there is the last stage PAC Filter that the water gets through before we drink....Nothing is perfect but I still believe is going to be heltier than purified water from PET:))Stay hydrated!
