Express Water Alkaline Reverse Osmosis Water Filtration System – 10 Stage RO Mineralizing Purifier – Mineral, pH +, Antioxidant – Under Sink Water Filter with Remineralization – 50 GDP

The RO system comes well packaged and each part is color coded for easy The instructions are very easy to follow with the color coding and step by step navigation. If you can assemble Ikea furniture you can easily install this unit by yourself. I was able to fit it under my sink even with a large garbage disposal there and still had room for cleaning products. I recommend giving the entire instruction pamphlet or read over before starting to assemble stuff. Most of the filter is pre-assembled. Really all one has to do is install the three main filters and attach a couple lines. Then follow the initial flush procedures. The hardest part is going to be drilling a hole in your stainless steel sink for the faucet. I followed the drilling directions on the faucet box. One your 1/8 bit stops penetrating, then switch to the quarter inch and that'll help mill it down. Once the quarter inch penetrated the stainless steel I switched to a cone bit. Drill at very slow speeds and squirt a little WD-40 around the bit drilling area to keep it cool. It took a little while however I was able to install the faucet on top of my stainless steel sink. Followed the flushing procedure and had no leaks and didn't have to adjust anything. The water pressure coming out of the RO faucet spicket was surprisingly good. I did some testing with a digital water hardness tester I bought from Amazon. My tap water hovers around 237 parts per million. This RO system, once it was flushed, was putting out drinking water that tested around 25 parts per million. That is excellent in my opinion because I'm also using the alkaline restore cartridge. Water tastes great and is refreshing and I'm very happy with this purchase. I use the filtered water in my coffee maker, humidifier and I fill up a half gallon jug to keep in the fridge for daily drinking water. I'll probably swap out the Chrome faucet for a brushed nickel to match the rest of my sink accessories.

The system was relatively easy to install. That's where the positive review ends. I've called customer service and received no call backs. I can't even fill up two gallons of water during a 24 hour period. I've expanded the bladder. I've tried everything in troubleshooting. One gallon of water a day is 30 gallons a month I'd be better off buying water and getting it delivered. Complete waste of money.

I love having it ! I needed to have it installed for me. I now have good water for tea coffee or just to drink and without having to lug cases of bottled water in from the car. I have another being installed for my refrigerator ( not close to the sink)

Poorly designed screw on filter cartridges prone to leakage unless really torqued down (their interpretation of "snug"). The filter wrench wouldn't allow for a good grip on cartridge cannister. I would use cartridges with quick connect fittings. Top of tank screw-on fitting leaked bad even when torqued down snuggly. Easy fix with a hose end washer and some food grade silicone sealant. Most important thing, "READ THE INSTRUCTIONS!"

This system was easy to install and has produced really good tasting water. I used to flavor my water but don't need to do that with the water from this system. I'm very happy that I found a great reverse osmosis system for a great price!

It was easy to install the system. Use for 3 months and had no issue, so far so good, water tasting good. This system is great RO for great price. Very happy with this RO system.

Product was pack with care, installation instructions were simple and clear. Its very easy to install and the customer service line is very helpful if you have any help during the installation. The water taste is great and we recommend this product and we will buy any product from this company.

After using the same RO System for years, I needed an upgrade. I came across express water's alkaline RO system and it seemed like it was I needed. I really liked the price of their replacement filters and accessories. So, I went ahead and got their Alkaline RO system. It came with free replacement filters and a water storage tank. Thanfully installtion was fairly easy. And my water definitely tastes better now. So I would definitely buy this system again.

This is our first reverse osmosis. Install was pretty easy and the instructions were easy to follow. The water tasted a bit different at first after the appropriate number of times emptying the tank and refilling after installing, so I did a couple extra cycles and now it tastes great! Refilling is silent and there is plenty of pressure in the tank. The tank is large enough that with 4 people in the household we are never waiting for it to refill. Very happy with our purchase!

This system was pretty easy to install and the water it produces tastes great. It fits well under my sink, the faucet doesn't take up much space, and I like that I can turn the faucet away from the sink if I need to. I was excited to find a reverse osmosis system that remineralizes the water for such a great price!
