So easy to replace cartridges

Pros: Easy to replace, effective tap water filtration

Cons: None, I've been using the system for a couple of years now

I love my Aquatic Life Twist-In RO/DI system. I used to use the RO Buddie from Aquatic Life and the Twist-In is so much easier. All of the cartridges are super easy to replace and work great. The instructions are very clear on how to perform replacements. It's fast, it's easy, and the cartridges are affordable and effective. I recommend the Twist-In system to everybody with a small tank (mine is 38 gallons). I have it hanging on the wall of my garage and it's connected to my garden hose.
