Best Reverse Osmosis Systems - Ranked by Family Size (2024 Guide)
What is the best reverse osmosis system for your family?
Prior to making a decision about how you are going to deliver reverse osmosis water to your home, there are a number of questions that you should have answers to.
- What is Your Water Source?
- Understanding whether you are accessing municipal or well water is important. Many RO systems are not compatible with well water and you will need to explore alternative options.
- How Much Water Do you Need?
- As you read-on through this post, you will notice that we refer to gallons per day (GPD) quite frequently. Smaller families will require a smaller GPD output than larger families.
- What is your Budget?
- In this post we will provide recommendations on "point of use" systems that are installed at your water source (typically in your kitchen). This Old House sets the estimate on point of use systems at an average of $350-$500. Larger whole home RO systems are much more expensive as they are providing optimal filtration for all of your water access points.
- What are your Water Treatment Goals?
- While the US is not known for having the worst water in the world, we certainly are not perfect. As testing has evolved, many municipalities are under fire for poor and often times dangerous water quality. Does the Flint Water Crisis ring a bell? Before purchasing an RO system, it is important to understand what you are trying to filter out of your water relative to the system you are looking at purchasing.
