Tankless reverse osmosis systems help save space and water with on-demand water filtration and space-saving designs.

Whether or not the drinking water in your home is safe to consume isn’t something that most homeowners think about. Unfortunately, for many people in some parts of the world, having clean water is considered a luxury and those with access to a dependable tap water source find it hard to imagine living without it.

Yet, even though you think that the water passing through the taps in your home is safe to drink, it is only sometimes the case.

To help filter out harmful particles, homeowners can install a tankless reverse osmosis system. These systems not only clean your water, but they can also save space and water at the same time. Read this guide to find out how tankless reverse osmosis systems save space and water.

How Tankless Reverse Osmosis Systems Save Space and Water

Tankless reverse osmosis systems can save space and water through space saving and economical designs, on-demand water filtration, fewer filter changes, and smart features! Below is an overview of the benefits you will notice almost immediately.

Space Saving Design

If space is limited in your home, but you want to provide your family with clean, fresh drinking water daily, installing a tankless reverse osmosis system is a great idea.

Most of these systems are a size that will fit comfortably in the corner of the kitchen cabinet beneath the sink without taking up too much space. This is because they are tankless, which means they have no storage tank.

Most of these systems take up around 18 inches of space and are no wider than 8 inches. But what makes them even more efficient when saving space is that everything is inside them.


Installing a tankless reverse osmosis (RO) system is an excellent idea if you want to save water and keep your home’s overall water consumption down.

Tankless RO systems only produce clean, fresh drinking water when you turn on the tap, which means that you aren’t using more water than is needed.

With a tankless RO system, you only need to use two gallons of water to make one gallon of clean drinking. Alternatively, reverse osmosis systems that include a tank require three gallons of water to produce just one gallon of drinking water.

With a tankless system, only waste water gets directed toward the drain in your home. So you end up with more of the clean filtered water coming out from the tap.

Along with helping you to save water, these systems can also prove economical in other ways. You will save money over time since you won’t need plastic bottled water. Additionally, most systems are cost-effective in that they don´t need a power source to be able to run.

On-Demand Water Filtration

With tankless reverse osmosis systems, there isn’t any risk of contaminated water containing heavy metals coming out of the tap. As soon as you turn the device on, it immediately begins the reverse osmosis water filtration process and the risk of any contaminants getting into the water is eliminated.

Fewer Filter Changes

You will find that installation of a tankless design ensures that they do not require filters to be changed often. Due to their size, the cartridges inside are made up of a combination of the different filtration stages. This makes them ideal for anyone who wants a system that requires little maintenance carried out on it.

Smart Features

As well as a sleek design, some of the best systems available today also come with cool features that you would not get if you invested in a tank-based reverse osmosis system.

Some of the features include a smart faucet, a built-in TDS reader, and a light to indicate when the filters need changing. All of these can prove helpful in ensuring that you maintain your tankless reverse osmosis system to a high standard.

Water Taste Improved

When you take a sip of water from a faucet with a tankless RO system installed, you will notice how much better the water tastes.

It will have a much cleaner, fresher taste, similar to what you would get from bottled water. The water you drink from a tap from a RO system with a tank may have an odd taste because it has been sitting in a water storage tank until needed.

Easy to Install and Maintain

The installation process for tankless reverse osmosis systems takes about 30 minutes to provide you with high-quality clean drinking water.

Due to their compact design, most tankless reverse osmosis systems are straightforward to install without the help of a professional.

Most systems come with a feed water adapter to make the installation more manageable. You attach this as instructed before installing one of these tankless RO systems with its semipermeable membrane.

Also, when it comes to maintaining these systems, you will find that changing the filters, including the semi-permeable membrane, has been simplified. In most cases, it is simply a case of unscrewing the outdated filter and then screwing in the replacement filters after you’ve opened the appliance up.


If you are still wondering whether to install a tankless RO system in your home, consider how tankless reverse osmosis systems save space and water. It’s also a good idea to think about how much safer your drinking water will be.

If you have several people living in your home and water supply consumption is high, installing such a system is a great idea. Water pressure will still be maintained while providing unlimited drinkable water on demand, without wasting water.

There are many different models available, so finding one that suits your budget and needs should not be difficult. These systems can cost anywhere from $300 to $500, depending on the size you want and want additional features it comes with.
