Great Water Filter
Using the item is easy. Installing it under my sink was somewhat easy. Hard to reach the connection under my counter. My son installed it for me as I could not reach the connection. Because of the difficulty to reach the connection the faucet becomes loose and I need to tighten it from underneath every now and then. Again my son has to do it. The filter is great. I love the taste and security of getting purified water.

Well designed, great instruction, easy install and great customer support
Purchase an RO system in mid December. Installed remotely without any issues; instructions are clear and thorough. Upon flushing noticed two small leaks on the preassembled unit. Called Express Water and they replaced the entire unit with no fuss at all. There was an issue and they make it right. Thank you for everything so far.

New filtration system
This is our first under the counter RO water system. This is a fantastic system. Instalation was simple and the instructions were very comprehensive. The first glass of drinkable water that came from this system was amazing. The water has wonderful taste and felt, in lack of a better term, lighter. It enhanced the flavor of our morning coffee and our tea. The flavor of our food is fuller after we rince or cook with the water from this system. My wife commented that the water from this system seems to come to boil faster. After experiencing what a system like this can do I will not go back to just the tap or pitcher filter. This investment was worth every penny.

Long overdue
I should have bought this over a year ago. I spent more on bottled water that it cost me for this. I got a 9.5 PH with this. Worth every penny.

Our fourth Express Water system
I like that the instructions are much clearer now than at times in the past, especially for yearly maintenance. Makes everything pretty easy. Will install sample tap between ro membrane and alkaline cartridge for more accurate tds/conductivity readings. Have recommended EW systems to many people. Very happy.
