Reverse osmosis (RO) technology is considered to be the last word in the water filtration system.
However, RO systems are further augmented with the integration of other filtration systems to make them 3, 4, or 5-stage filtration systems to make them capable of filtering any kind of water, including well water.
Here, I am providing reviews of the 4 best reverse osmosis systems for well water:
What Is the Best Reverse Osmosis Water System?
- Best Whole House: iSpring RCS5T
- Best Under Sink: NU Aqua Platinum Series Deluxe

About 13 million homes in the US rely on well water for drinking, cooking, cleaning, and watering. Most of these homes are located in the eastern half of the US.
About 20% of these wells are contaminated. The concentration levels are above the recommended and present a risk to our health. That’s why it’s imperative to invest in a water filtration system capable of removing these contaminants. This is where reverse osmosis comes in.

Reverse Osmosis System Buying Guide
Buying a Reverse Osmosis (RO) filtering system is a great investment because it will ensure that you drink only clean, healthy, and safe water.
However, there are many RO products on the market and your decision can turn out to be a flawed one just because you did not know what features will suit you more than the rest.
To buy the best reverse osmosis system for well water, you need to take home a system that can clean water in multi-stage filtration, including:
- Big-size debris
- Heavy metals
and other common water contaminants.
Before you make the purchase, you may want to know a little more about RO so that you can make an informed decision about which brand and model to go for.
Here, I am providing you a detailed buying guide for buying the best reverse osmosis system for well water:
The RO system would be placed in the cabinet beneath the sink.
My experience says you need quite a bit of space there and you might have to permanently remove the trash can from there.
Even after removing it, you may have to struggle for space with pre-filters, RO components, and the tank all going in there.
It’s better that you measure that space before going to the shop or ordering the RO unit online.
Make sure the unit and model that you are buying fits in comfortably in the limited space under the sink.
Before you place an order, check out the water pressure in your home because the RO devices will not work efficiently if the water pressure is under 40 PSI.
However, you can increase the pressure of the waterline by using a boosting pump.
Many reverse osmosis units come with built-in booster pumps.
If the water pressure is an issue, you can try to solve it with a reverse osmosis unit that has a built-in booster pump.
If despite the booster pump, water pressure is not up to the required level, your RO system will not work efficiently.
A primary concern with reverse osmosis systems is that it consumes more water to clean than it produces for drinking.
In other words, it wastes 50% to 60% of water to produce 50% to 40% clean potable water.
This is an important consideration for some people who may not have the option to waste so much water.
Source of Water
The source of water is important for choosing the right variety of the RO system.
While it’s a robust filtration system that can clean any kind of water including the well water, I would suggest you check the description and make sure that it does filter it before you buy the machine.
The reverse osmosis technology is so sweeping and powerful that it removes even some of the healthy minerals and salts from the water.
You can consider using a remineralizing alkaline filter that reintroduces these healthy minerals.
The RO system is used in different industries to remove contaminants from the water. For example, it is used to remove salt from the saline water of the sea.
You too can use it for different purposes than simply using it for cleaning your household water.
For the RO water filter to function the way it did when it was new it requires you to do regular maintenance.
To add to your woes, some filters require more frequent replacement
You need to keep track of the timeline when the filters need to be replaced.
For some people, this is a tiring exercise.
Before you buy an RO system, I would suggest you properly understand its filter maintenance and replacement requirements so that you can settle for one that is more convenient to you.
Think it Well
These factors require proper thinking and planning so that you don’t have to put up with an expensive RO system that does not quite fit your situation.
If you have thought out all available options, you may find a RO system that is more compatible with the specific situation in your area and home.
What Size of RO Do You Need?
A Reverse Osmosis water filtration system operates well when the water pressure is between 40 PSI to 100 PSI.
A typical system generates 10 to 100 gallons of clean water per day.
Generally speaking, an RO system produces 50% to 60% of its GPD (Gallons per day) rating.
Critical Information About Well Water
As mentioned before, 13 million homes use well water as their main water source.
According to a study conducted by the US Geological Survey, 20 percent of these well’s water is highly contaminated.
Some of these contaminants are:
- Heavy metals
These contaminants affected the taste and smell of the water in half of the wells.
Below you’ll find information about well water in the US and the reasons why choosing a water filtration system is your best choice.
Is Well Water Regulated?
No, it’s not.
The United States Environmental Protection Agency (EPA) does not regulate private wells. You are responsible for testing your well water and making sure it is safe.Source: Center For Disease Control And Prevention
The US government considers wells as private assets.
That’s why they won’t test them
And if you get water poisoning, guess what, it’s your fault.
What Are The Problems With Well Water?
Apart from not being regulated and you being responsible for your own health, other issues include:
If the water is really hard then you’ll have to descale your appliances quite regularly.
Also, your clothes will lose their color, your hair and scalp will become flakey, and given enough time the water pressure will drop significantly because of limescale buildup in the pipes.
Is the water blurry? Does it have that distinct metallic taste? Do you see corrosion and/or rust around the pipes and faucets?
Then you most likely have acidic water.
If you’ve seen reports about acid rainfall in the vicinity, then you definitely have it.
A simple pH test will show you how exactly acidic your well water is.
Your teeth are becoming more and more yellow.
Does your water smell like rotten eggs?
Also, this stuff is flammable and some people tested the presence of it in their well water by lighting a match or a lighter when they opened the faucet (This is dangerous BTW. Do it at your own risk!)
Viruses and Bacteria
As nasty as this sounds, even fecal bacteria can find their way into your well.
How Do You Fix Bad Well Water?
Well, the simplest and most straightforward solution is to invest in a high-quality reverse osmosis water filtration system.
