The SpringWell RO is the best tank-based reverse osmosis system available. The 4-stage process removes thousands of harmful water contaminants and works on both city water and well water sources. We installed and lab tested one of these units under our kitchen sink to see how if it lived up to expectations.
In this SpringWell reverse osmosis system review, we discuss the pros and cons, provide a step-by-step installation guide, and look at the system performance using an independent laboratory test.
SpringWell Lab Test Results
To performance test the SpringWell unit, we performed a before and after test using a certified laboratory. The initial water sample showed elevated contaminant levels of bacteria, sodium, TDS, chloride, sulfate, fluoride, radon, uranium, and lithium. After installing the point-of-use RO unit, there was a significant reduction or elimination of all of the harmful contaminants.
Bacteria, Sodium, and TDS were all reduced by approximately 95%. Chloride was reduced by 85%. While the nasty contaminants like fluoride, radon, uranium, and lithium were all completely eliminated. We posted both lab test results in the links below so you can review them in detail.

How Does The SpringWell RO System Work?
The SpringWell uses a 4-stage reverse osmosis process that is capable of removing thousands of harmful contaminants from your drinking water. The semipermeable RO membrane used has pores that are only 0.0001 micron, which is small enough to only allow pure H2O molecules to pass through.
- Sediment Pre-Filter: Catches large debris, rust, sand, and dirt.
- Carbon Block Pre-Filter: Removes chlorine, bad taste, and foul odors.
- RO Membrane: Removes thousands of harmful drinking water contaminants including lead, PFAS, pesticides, pharmaceuticals, bacteria, VOCs, and more.
- Carbon Block Post-Filter: Finishes the water and removes any remaining contaminants that may have been transferred from the storage tank.
Installation Of The System
Installation of the system is made easy since it comes with all the components you need. If you are a DIY kind of person, this is absolutely a task that you can handle. It took us just over an hour to install ours. The only required equipment you will need is a drill.
If you are not comfortable installing the unit on your own, you can hire a plumber for the task. Because it is a point-of-use system, it should be an easy job for a professional and should not cost too much.
In our SpringWell reverse osmosis system review video below, we walk through step by step how to install the unit. I highly recommend checking it out to see what is involved.

Pros Of The SpringWell RO System
Unparalleled Performance
The four-stage filtration process in the SpringWell RO has the ability to remove over 99% of harmful contaminants. This means you can have bottled water quality water right at home.
High Water Flow Rate
The unit has a high 75-gallon per day (GPD) flow rate. Combined with a 3.2 gallon storage tank, you wont have to wait around to dispense your purified water. The best part is it works even if the power is out, so you have emergency drinking water stored in the tank.
NSF Components
Although the system as a whole is not NSF certified, the components used are. This gives peace of mind that the parts are manufactured to the highest standards possible.
Easy Maintenance
Once the system is installed, it is very low maintenance cost. The pre and post-filters only need to be replaced every 6 months and cost between $20 and $30 each. The semipermeable RO membrane can last up to 24 months and will cost about $100.
The unique twist and lock filter design allows for filter replacements in a matter of seconds. It doesn’t require a filter wrench or tools. Simply twist the filter a quarter turn with your hand. And since the unit uses an integrated filter cartridge design, it won’t harbor bacteria like other RO models that utilize external filter housings.
Lifetime Warranty & 6 Month Guarantee
SpringWell is one of the few companies building products in the USA. They back the system with a lifetime warranty on tanks and valves and offer a 6-month money-back guarantee.
Cons Of the SpringWell RO System
Point-Of-Use System
This is a point-of-use (POU) system that will only address the water from one location. It is installed under the sink and primarily used for drinking water and cooking. If you want comprehensive water filtration throughout the house, a whole house system could be ideal.
Keep in mind that many times a whole house system and a POU reverse osmosis system are paired together as the RO still creates some of the purest drinking water possible.
Additional Filters Are Extra
Some RO units will include things like remineralization filters or UV purifiers. And while those items can be good, they are not necessary for all circumstances, and those systems will cost a little. If you like the mineral water taste or have serious bacteria issues, you can always add them to the SpringWell. If you do not need them, you can save some money!
