However, it's worth noting that the APEC Water Systems RO-CTOP-C system has a simple installation process, but is not compatible with certain types of faucets. If you have a pull-out, sprayer, or special size designer faucet, the APEC Water Systems RO-CTOP-C will not be able to connect to your sink.
3. AlcaPure RKIN-ZIPAL – Best Design & Performance
The AlcaPure RKIN-ZIPAL System is notable for its style. It has sleek edges, bold color, and modern design. AlcaPure understands that buyers don't have to sacrifice style when purchasing a water filtration machine.
The AlcaPure RKIN-ZIPAL is a compact water filtration system that can be easily placed in a kitchen, dorm, or RV. Its unique design has the supply water tank on the front, which allows for extra space on the sides and back. This makes it easy to fit the machine under cabinets or inside cabinets, or even display it on a table.
The AlcaPure RKIN-ZIPAL is also highly effective at removing contaminants from drinking water. Its filtration system removes 99% of contaminants, including fluoride, chlorine, heavy metals, lead, PFOA, and PFOS.
One of the standout features of the AlcaPure RKIN-ZIPAL is its water-saving capabilities.

The rejected water that is suitable for drinking is also easily accessible and can be used for other purposes, such as watering plants or washing produce.
However, there are some drawbacks to the AlcaPure RKIN-ZIPAL. Some customers have reported issues with the customer service team being unresponsive when they have problems with their machines. Additionally, the machine doesn't have sensors to detect when the top chamber is partially full, which means it cannot be filled when this occurs.
4. APEC Water Systems RO-CTOP-PHc – Best for pH Levels
APEC's APEC Water Systems RO-CTOP-PHc machine made it onto our list again. It has many of the same great features as the original APEC RO system.

There are a few drawbacks to the KFLOW KFL-ROPOT-180 Plus. The jug only holds 1.5 liters, making it more suitable for single use or for those living alone. Cleaning the tank can also be a bit challenging. However, overall, the KFLOW KFL-ROPOT-180 Plus offers a superior water recycling mechanism and prioritizes health and safety in its design and construction.
6. Waterdrop G3 – Best for Bacterial Buildup
The Waterdrop G3 has a cross filtration system that removes bacterial and virus buildup within the machine. This sets it apart from its competition.
Some water filters accumulate harmful bacteria, viruses, and microorganisms because water remains inside the machine even after passing through the filters.
The Waterdrop G3 has an alert notification system that goes above and beyond others. While other countertop reverse osmosis filters only let you know when the filter is no longer working, the Waterdrop G3 has three lights: “perfect,” “replace soon,” and “replace now.” This way, you have plenty of notice to buy a new filter instead of running out unexpectedly.
The Waterdrop G3 TBS Smart Monitoring Panel also shows you how many contaminants have been filtered out of your waste, allowing you to see the difference firsthand. This adds to the overall satisfaction of using the product.
However, some customers have reported that the indicator lights on the Waterdrop G3 begin to fail after extended use. Additionally, the customer service for Waterdrop G3 has received criticism for being difficult to reach and often leading to automated answering machines rather than live representatives.
7. Express Water Countertop RO System – Best For Large Families
The Express Water RO Countertop system can pump four gallons of water per hour. This makes it a good choice for homes with multiple people.
The Express Water countertop RO system is a good choice for large families because it is faster than other water filter machines. It uses a 4-stage water filter system to remove 99.99% of contaminants. This system includes a sediment filter, granular carbon filter, reverse osmosis membrane, and a post-activated carbon filter.
However, you shouldn't use hot water with this machine because it can damage the filters. Additionally, you may need to purchase an adapter if you don't have a specific type of faucet.
One potential issue with the Express Water RO system is that the water drip is slow. This can be inconvenient if you are in a rush or have a lot of people over. To avoid this issue, make sure to fill up the water tank when you are not in a hurry.
Weighing the Benefits and Drawbacks of a Countertop RO Water Filter
Water purification systems are important due to global industrialization and the threat of water pollution and scarcity. Access to clean, great-tasting drinking water should be available to everyone. (2)
Reverse osmosis water filters are relatively cheap and extremely effective at purifying water. They also have a long lifespan and require minimal maintenance. Many reverse osmosis water filters are compact, making them suitable for small spaces and accessible for urban residents, students, travelers, and others.
Does it Offer Health Benefits?
Is reverse osmosis water good for you?
The countertop reverse osmosis water filter system is a home solution that cleans city or well water by removing harmful organisms and chemicals, such as nitrates, sulfates, fluoride, and arsenic. This makes reverse osmosis water a healthy alternative to bottled water, which may contain harmful microplastics.
However, reverse osmosis systems also remove healthy minerals from the water, like magnesium, calcium, potassium, and sodium, which the body needs for proper health. It's thought that the body is more efficient at absorbing these minerals through food rather than water.
Countertop RO System Buying Guide: How to Choose the Right One
A reverse osmosis water filter can seem intimidating to understand, even in a countertop unit. However, you can learn more about how it works and what to consider when purchasing one through our buyers' guide.
Water quality and contaminants in your area
Check the quality of your water before purchasing a countertop reverse osmosis system. Look for potential contaminants. You can use a water testing kit or contact your local water utility for a water quality report.
For example, if you live in an area with high levels of lead in the water, a reverse osmosis system can effectively remove the contaminant.
Type and size of the system
Countertop reverse osmosis systems come in two types: standalone units and ones that attach to your faucets. Consider the type that fits easily on your countertop. If you have limited kitchen counter space, you may want to consider a smaller, faucet-mounted system.
Flow rate and water production capacity
The flow rate of a reverse osmosis system refers to the amount of purified water it can produce in a given time period. It's important to consider the flow rate when choosing a system for your household. A system with a high flow rate may be more suitable for large families.
Maintenance and filter replacement frequency
Countertop reverse osmosis systems require regular maintenance, such as filter replacement, to ensure optimal performance. Consider the frequency of replacement tasks and whether you will perform them yourself or hire a professional. Also, consider the price of replacement filters before purchasing.
If you prefer to perform maintenance tasks yourself, choose a countertop RO system with easy-to-replace filters.
Countertop RO System Filters
Filters in any size countertop system work by using water pressure and membrane filters to purify water. They do this by moving unfiltered water through semi-permeable membranes. Any contaminants in the water are unable to pass through these membranes and are removed from the water as it passes through each filter until it reaches the holding tank. The contaminated water is then flushed down the drain.
To ensure the best taste and longest filter lifespan, look for systems that have at least four filters and indicator lights that alert you when it's time to replace the filters.
Most reverse osmosis water filters do waste a significant amount of water. Even in small countertop units for RVs and apartments, wastewater is produced as a part of the filtering process.
It's important to note that some systems can waste up to 20 gallons of water when producing one gallon of drinkable water. However, this is not always the case. Filters like the KFLOW waste less water than others. It's important to consider your comfort level with the amount of wastewater produced when deciding which reverse osmosis system to purchase.
Some countertop reverse osmosis systems are more energy efficient than others. If you want to save money on your energy bills, look for a system that is Energy Star certified. An Energy Star certified system may use around 50 watts of electricity per hour, while a non-certified system could use up to 85 watts per hour.
Price and budget
When purchasing a countertop reverse osmosis purifier, consider your budget. These purifiers are typically priced between $180 and $450 due to their advanced technology. The specific cost will depend on factors such as the chosen product, desired features, and reliability.
Choosing the right reverse osmosis water filter for your home can be stressful. There are many products to choose from.
To help you, we have listed our top picks for countertop reverse osmosis systems. AquaTru is our top pick due to its features and water pumping capabilities. However, all options on this list are leaders in the industry.
