Great cost-effective RO system filter replacement kit from the original manufacturer
I purchased my original Express Water reverse osmosis system almost ten years ago for the kitchen sink and it has been working great ever since. The original product came with two sets of filters which I kept in service for way too long. I am going to be much more diligent on filter changes now and purchased this replacement filter set which is sold by the original manufacturer. I had a plumber here for another job, so I just had him change the filters for me including the RO membrane. Luckily I kept the round plastic wrench from the original kit which slides over the filter holder body and grabs the ridges perfectly which makes it a lot easier to unscrew. For a few bucks, they should include one in this replacement kit because I'm sure most people don't remember to keep it. Replacing the filters was completed pretty quickly with no snags. Be sure to read the instructions and properly flush your reverse osmosis system properly after replacing the filters.

Great Filters, Great Water Flavor
Everything fit great. Installation was moderately simple. The 5th filter did not fit with the existing connections in my system, but a trip to Home Depot for a couple of new quick connects and $5 later, everything is working great. My system is about 10 years old, so I'm sure the connections were just dated anyway. I ran the water through the RO system for an hour and it tastes better than ever. Its taste rivals bottled water. I drink about a gallon of water a day, and after a week there seems to be no degradation in the flavor of the water. Rated 4 stars as instructions were not included. Even a simple diagram would be much appreciated. Thankfully, I'm not so dumb I couldn't figure out how to hook everything back up after replacing the filters.

Absolutely love this filter
Was time to change my filters for their 6 month change and it just shows how much it does for your drinking water. I always grew up with a reverse Osmosis filtration system in the house and put one in when I bought my own place. My town uses well water so it's quality isn't consistent. Since getting my filters it's been consistent. The taste and smell are high quality and affordable with less spent than on Britta filters.

Replaced my ROS filters.. Affordable and fresh clean safe water! I'm using ROS for 30 years now.. All my kitchen pots, pans and kettles, my humidifier etc. are cleaner, last and last and last.. Before ROS I'd have to purchase a new humidifier every 2 winters.. most of my gadgets that use water are lasting over 10 years and more unless an accident. They happen you know.
