How Much Does a Reverse Osmosis System Cost?
Here are some of the main factors that determine the final cost of a reverse osmosis water filtration system:
1. Upfront Cost of System
These are some of the characteristics of reverse osmosis systems that contribute greatly to their initial cost:
Bigger is not always better but it usually is when it comes to reverse osmosis systems. For a reverse osmosis filtration device to produce more purified water, it must have larger size individual stages that contain the appropriate amount of filter media or membranes in them.
So, the more purified water gallonage that a reverse osmosis system can produce, the more you can expect to pay for it.
Number of Stages
You would be hard-pressed to find a single-stage reverse osmosis system. That’s because at the very least they will usually have some type of sediment-catching pre-filter. That makes two stages right there and most reverse osmosis systems have at least three.
Other types of stages these water purification devices use include mineralizers, water conditioners (salt-free water softeners), UV light disinfection, and stages that can contain all different types of activated carbon filters.
It only stands to reason that the more stages that a reverse osmosis water treatment system has the more it will cost.
When shopping for a new reverse osmosis water treatment system, it’s no different than with most other products in that some manufacturers’ names carry more weight with prospective buyers than others.
So even if two reverse osmosis systems have almost identical characteristics, you can expect to pay more for the one that is made by the more reputable manufacturer.
Popular reverse osmosis manufacturers include Waterdrop, iSpring, and Crystal Clear.
2. Cost of Installation
I will start by saying that this is one of the costs associated with purchasing a new reverse osmosis system that’s the hardest to predict. For example, if you are a do-it-yourself type person then this cost would be zero.
On the other hand, for someone that does not have the knowledge or time to self-install their new reverse osmosis water filtration device, this cost could be significant.
3. Other Costs
There are a few other minor costs that you should be aware of when purchasing a reverse osmosis water purification device. These include the maintenance that you need to have performed on them and the cost of a system’s replacement filters.
These are the typical cost ranges of the main categories of reverse osmosis systems:
- Countertop RO Systems w/self-install: $100 to $350
- Under Sink RO Systems w/self-install: $200 to $700
- Tankless RO Systems w/professional installation: $700 to $1500
- Whole-House RO Systems w/professional installation and 500-gallon plus storage tanks: $7,000 to $10,000
How Much Do Whole-House Reverse Osmosis Systems Cost?
We have already discussed that the most widely used types of reverse osmosis water purification systems are those that are made to install under your kitchen sink or be placed directly on your kitchen countertop.
Much of this has to do with cost.
The bigger the reverse osmosis filtration setup, usually the more it will cost you. That’s why you mostly see reverse osmosis filters that only treat the water that’s used for drinking and cooking.
Reverse osmosis filters like these that are placed near a kitchen sink are referred to as point of use (POU) filtration systems.
But you can also step up the water filtration level in your entire house if you have a generous enough budget to invest in a point of entry (POE) reverse osmosis system.
Here is an example of how you can do that with a true whole house reverse osmosis system:
The above product is what’s known as the Crystal Quest Whole-House Reverse Osmosis System. It can produce a whopping 7000 gallons a day of purified household water. It does this through the use of four filter stages.
You may be wondering what sets this system apart from typical point of entry (POE) reverse osmosis systems that make them so expensive?
For starters, you will need to purchase a very large capacity storage tank. This is essential for any type of whole-house reverse osmosis water filtration system because they don’t filter water on demand.
That’s because the advanced filtering membranes used in these systems do not easily allow water to pass through them because of their incredibly small pore size. This is a tradeoff for them being able to produce the highest quality water of any home water enhancement device.
Most people who can afford true whole-house reverse osmosis systems will purchase at least a 500-gallon water storage tank.
The reason for this is that according to the USGS (United States Geological Survey) each person in a home uses an average of 80 to 100 gallons a day. So, if you have a family of five, a 500-gallon tank most likely will cover your family’s daily water use needs.
The water storage tanks for these systems alone will add over $1000 to their cost.
Other significant cost factors of whole-house reverse osmosis systems include the booster pumps that are required to add extra pressure during its operation and a sophisticated float system that is placed in the storage tank to make sure that is always filled to capacity.
What is the price tag of this whole-house reverse osmosis system with an included 550-gallon storage tank?
It will set you back over $9000 and that does not even include the price of installation. It’s a very typical price range for what I consider to be a true whole-house reverse osmosis system.
This is the reason why so many people like me choose to use a carbon-based POE filter working in tandem with a good POU reverse osmosis system.
You will then get decent quality water to use throughout your whole house and excellent quality drinking water for around $1000.
Can a Tankless Reverse Osmosis System Be Used for the Whole-House?
When looking for a whole-house reverse osmosis system, you will come across high-capacity tankless (direct flow) reverse osmosis options. Many of these can produce up to 600-gallons of purified water a day.
They can do this because they come with booster pumps and more membranes which allow them to purify water faster.
Keep in mind though that they still don’t produce purified water on demand. That’s why most manufacturers recommend purchasing a storage tank that holds around 5 to 20 gallons of treated water to be used in conjunction with them.
This will help avoid short periods of water outages. It’s also something that may change your mind when it comes to thinking about using them as a whole-house filtration system.
Here is an example of what I am saying about a tankless reverse osmosis system in some cases not being the perfect whole-house water purification solution:
This is the iSpring RCB3P Reverse Osmosis RO Water Filtration System. It’s an excellent quality, commercial-grade, tankless reverse osmosis system that is capable of producing up to 300 gallons of purified water per day.
The most commonly used storage tank sizes that are associated with this product hold either 11 or 20 gallons of treated water.
Since reverse osmosis systems do not produce purified water on demand, a shower or two could leave you without water for a short time.
The best trait of these systems when it comes to potential use as a whole-house reverse osmosis system is their much smaller price tag. Usually, they will run you less than $1000 with an added storage tank.
Direct flow reverse osmosis systems are also very commonly found in commercial settings such as offices and restaurants.
Are Reverse Osmosis Systems Worth the Price?
This is a hard question for me to answer for you. I won’t pretend to know your budget concerns or what else is important to you when it comes to your tap water quality.
What I will tell you is that you really can’t put a price tag on your family’s health and the quality of the drinking water that they consume definitely has a role to play in that.
For me, it was an easy choice to purchase an under-the-sink reverse osmosis system. I feel that my family is healthier because of it and I enjoy the looks and the taste of the water that this type of purification system allows me to have.
