Such a unit would offer the ideal pure and healthy water for your family and is also more convenient to handle than other cleaners, thanks to its small size. In fact, it’s currently the most popular type of water purifier!

But we know that there are lots of options available to choose from, due to which making the right choice can become difficult. And it’s here that we’ll help you out by providing this comprehensive guide on the 6 top-notch options to consider. 

Best Countertop Reverse Osmosis System 

So, if you're ready to take a step towards healthier and purer drinking water, without the need for complex installations or modifications, here's the list of the 6 best countertop reverse osmosis systems to meet your needs.

1. AquaTru AT2010

By bringing home this pro from AquaTru, you can always get the much-desired clean water free from almost all contaminants. Equipped with superior purification technology, it helps in providing consistent service for years to come. Also, the brand offers a beneficial 30-day money-back guarantee for this unit.

Why Did We Like It?

First things first, this unit offers clean and pure water by practically removing all contaminants threatening your health. What makes this possible is AquaTru’s patented high-standard reverse osmosis technology, which has the power to remove as many as 83 contaminants, including lead, nitrates, PFOs, fluoride, chlorine, and more. 

Furthermore, it has been tested and certified by the International Association of Plumbing and Mechanical Officials (IAPMO) to be truly effective on all these contaminants. We were also impressed with the twist and seal filters that came with this system, each of which could purify 600 to 1200 gallons of water. 

This implies you will require only one filter change in a span of 6 months to 2 years. So, you don’t need to worry about frequent filter changes or using expensive bottled water, like with ordinary water purifiers. 

We also found the removable water dispensing tank to be very convenient as we could store it in the refrigerator to chill the filtered water.  

What Could’ve Been Better?

This model comes with a warranty period of 1 year, which we felt was insufficient for an RO water purifier. In fact, most customers consider a longer and more reliable warranty to be an important factor when purchasing water purifiers. But with regard to its performance, we didn’t face any issues. 

2. Express Water EZRO5

The Express Water EZRO5 is another unique RO system that can be the ideal go-to water purifier for all household purposes. Featuring a new and improved working mechanism, this unit does away with the need to keep bottled water at home since you get much purer water anytime you want! To know more about it, let’s move on to the next few sections.

Why Did We Like It?

The best thing about this unit is its unique design, which consists of a dedicated faucet for filtered water fixed on the topmost filter. This is unlike most other ordinary RO systems in which clean water comes out from the faucet adapter. 

As such, it’s a suitable unit for those who don’t want an adapter for the faucet in their kitchen. Another major benefit of this feature is that it lets you carry the unit anywhere you want, thereby enhancing the portability factor.

Even the straightforward 4-point system for connecting the parts is praiseworthy as it simplifies the installation procedure while also preventing leakages. Plus, you won’t need any tool for the installation, so brownie points are awarded!

Coming to the filter changing system, it’s pretty effortless since all the 3 filters are incorporated in the unit, so all you need to do is just swap them. And they need to be replaced just twice a year, which means you’re relieved from the hassle of frequent replacement.  

What Could’ve Been Better?

Sure, this unit works wonderfully to deliver pure water whenever you need it and is also quite convenient to use. However, it doesn’t come with a case around the filtration system, which somewhat reduces its visual appeal in comparison to other units such as our previous pick. 

3. AlcaPure RKIN-ZIPAL

Halfway through our list, we’ve picked this stylish RO system from AlcaPure that delivers pure water each time. It comes with a slew of features that work to enhance user convenience to a great extent so that getting purified water anytime and anywhere becomes super easy.

Why Did We Like It?

First and foremost, the filtration system of this unit includes an additional post-filter that helps in delivering healthier water compared to other high-performing models. After the efficient reverse osmosis filtration functionality removes 99% of contaminants from the water, it moves into this filter to enhance its quality. 

Interestingly, users can choose between two types of post filters as per their preferences, namely, AlcaPure and OnliPure. 

While the former variant works to increase the pH of the water by infusing minerals such as Calcium and Magnesium, the latter reduces the number of leftover chemical contaminants. 

In addition to this, purified water can be obtained with the push of a button, that too, just within 15 minutes of adding the water into the bottom pitcher. This unit also ranks high in terms of space efficiency, as it has a compact rectangular design that can fit in compact spaces.  

What Could’ve Been Better?

Some buyers have reported that this RO system may arrive without the power cord in the package. So, make sure you check the package thoroughly to ensure all components are provided therein. In case you find something missing, immediately report it to the manufacturer.

4. SimPure Y7P-BW

Towards the end of our list, we’ve included yet another unit from SimPure that features an improved functioning and also sports a more appealing design compared to its predecessors. It offers greater reliability and convenience to users and can put an end to their dependence on impure tap water.

Why Did We Like It?

To begin with, this filter uses the latest UV technology for purification so that you get ultra-pure water free from almost all microorganisms. This feature works to remove the dead organisms floating in the water after the RO filtration system has already killed them. You can think of it as a means of double filtration.

For initiating the flushing action, there are both automatic and manual flushing modes to suit different user preferences.

You will also like the compact yet slim and elegant design of this RO system, which adds to its physical appeal. And as for the pure-to-wastewater ratio, it is the same as the Simpure Y6, making it equally capable of reducing water wastage by recirculation. 

Furthermore, it allows you to obtain purified water as per the volume you need. This is made possible by a touch control setting that lets you choose the required dispense volume between 6, 12, and 15 fl oz or activate continuous flow mode.  

What Could’ve Been Better?

Most customers were happy with the performance of this RO system as it delivered the ultra-pure water as it claimed. However, they pointed out that the dark exterior surface of the water reservoir made it a bit difficult to keep track of the water level.

5. Frizzlife RO Reverse Osmosis Water Filtration System

The Frizzlife RO Reverse Osmosis Water Filtration System makes a significant impact with its tankless and efficient design. By skipping the water tank and opting for a direct connection to the water line, the Frizzlife RO system saves you considerable countertop space and does away with the need for constant refilling. But its benefits don't stop there.

Why Did We Like It?

Apart from its space-saving design, this system impresses with its output, capable of processing up to 600 gallons a day, catering effortlessly to large families. Its filtration system involving eight stages integrates a special filter that re-alkalizes water to a pH level of over 7.5, providing more balanced water and thus contributing to health benefits. Also, it stands out with its user-friendly interface, featuring a real-time filter status display. This system indeed masters the art of marrying convenience with efficiency.

What Could’ve Been Better?

As much as we appreciate the user-friendly benefits, we did notice that this system lacks smart features. Additionally, setting up the system might require a bit more effort compared to other models.

6. ICEPURE Countertop Reverse Osmosis Water Filtration System

No products found.

Why Did We Like It?

The environmentally-friendly ICEPURE system comes with an elegant design that makes it a pleasing addition to your countertop. Its impressive functionality, thanks to the low water waste system that saves your bills, adds brownie points. But what makes ICEPURE stand out is its convenient features. With pre-set water output options and different temperature settings, it's almost like having an intelligent assistant at your disposal. Efficiency has never looked so good.

Buying Guide For The Best Countertop Reverse Osmosis System

For choosing the right countertop reverse osmosis system for your home, it’s definitely important to go through the details of some high-performing units. But the work is only half-done until you take into account some key characteristic features of RO systems. 

Making a hasty decision by just glancing at some specifications may fetch you only partial results. On that note, we’ve listed some essential factors that you need to keep in mind before proceeding to purchase a suitable RO system. Check them out below:

1. Water Output

This is a crucial factor to consider when choosing an RO system as it directly determines the speed of water dispensation of a unit. The water output is generally measured on a gallon-per-day basis and can be found in the product description for each unit. 

Besides, the water output gives you an idea about the efficiency of the purification technology. In this regard, some filters can eliminate the contaminants faster than others so that you get more purified water at any point in time. 

To get a unit with the ideal output, you must have an estimate of the amount of purified water you would need daily. For instance, users who engage in cooking or other activities that need lots of water would require a unit with a greater water output and vice versa. 

2. Pure To WasteWater Ratio

Checking the pure-to-wastewater production ratio of a unit is also essential since it determines the amount of wastewater that is drained out for disposal after each filtration. Naturally, users will want the maximum quantity of water in the reservoir to be purified, so a good-quality RO system should have a greater pure-to-waste water ratio. 

This ratio, in turn, would vary according to the pressure at which the water is forced through the filters in the unit. The higher this pressure, the more pure water will you obtain from the filter for any given amount of water added to the reservoir. However, other factors such as water quality, temperature, and pH also influence this ratio. 

Before choosing a suitable unit, you should keep in mind that an RO system with a pure to wastewater ratio of 4:1 or above is considered ideal for residential use. 

3. Filter Replacement

The pure and healthy water that every user desires is produced by the filter cartridges in an RO system. So, they are of paramount importance when it comes to choosing the right unit. And when the contaminants collecting in the filters increase to a certain level, you need to replace them with new and fresh ones. 

Considering this, the annual frequency and technique of filter replacement affect its performance to a great extent. Note that the filter replacement frequency for a good-quality RO system is once or twice per year. 

With regards to the technique, more convenient units allow users to replace filters very easily within just a few seconds. For instance, the filters for the KFLOW unit that we discussed above can be replaced by unscrewing the back cover and putting in the new cartridges, much like replacing batteries in a remote. 

But you should also keep in mind that if the water supply at your home has a high amount of a particular contaminant, it may require you to change the filters more often. Hence, it’s best to have your water tested if you’re not sure about which RO system will work best. 

4. Certifications

Although most users tend to overlook this factor, it tells you a lot about the efficiency and reliability of an RO system. After all, a certification guarantees that a certain unit can reduce a substantial amount of contaminants in the water that are otherwise harmful for your health. 

The most coveted certifications include those offered by NSF/ASI and the Water Quality Association or WQA. 

Notably, the former proves that the filtration system complies with the technical requirements for the removal of specific contaminants. On the other hand, the latter provides listings to prove that the filter has been tested and approved to comply with the claims that the manufacturer is stating. 

While going through the product information, make sure you check whether the unit comes with a certification for water quality, such as the ones discussed above. 

5. Remineralization 

This is a major differentiating factor for RO systems as it enhances the efficacy of a unit by a great extent. A water purifier that includes a filter for alkaline remineralization provides water with natural magnesium, calcium, and other beneficial minerals.

Thus, it will let you derive water that is not only bereft of almost all harmful microorganisms but also more healthy for your body system. 

The water that collects in the jug of the models containing a post filter for remineralization is known as alkaline water since it has a greater pH than regular water. Likewise, the units which don’t have such a filter produce water with a lower pH, which is referred to as acidic since it doesn’t contain the beneficial minerals. 

Remember that not all units come with this feature, so you must check the product information for the availability of an alkaline remineralization filter. 

6. Maintenance

Proper maintenance is a significant factor to consider while choosing an RO system since its performance will also depend on how well you can take care of it. Obviously, those that are easier to maintain are always preferred by most homeowners. 

This is why it’s essential to check whether there’s any information provided on the maintenance required for the unit. If you’re not clear about the same, you can contact the customer support facility for a brand. 

The cost of maintenance is also something that you’d want to consider as it includes the annual cost of replacing the filters and other related elements of the purification system. At the same time, don’t forget to check the availability of filter replacements for the unit you’re considering. 

7. Design And Installation 

The design of the RO system must also be considered since an ideal RO system should be convenient to handle and operate. Here, you’d want to check the ease of refilling the reservoir as well as handling the jug where the water is dispensed. In addition, many models come with indicators for filter replacement and touch controls for obtaining water as per your consumption requirements.

Another major factor is the ease of installation, so make sure you go through the installation procedure mentioned in the product description. 

Plus, some RO systems have to be connected to a faucet after installation, while others use an electric connection for operation. Therefore, you have the liberty of deciding on the type that will be more convenient for you.
