The distinct characteristics and advantages of tankless reverse osmosis water filtration systems make them a particularly attractive choice for drinking water filtration at a single point of application.

We have all of these systems set up in our lab, and we can show you which ones are the best based on our in-person testing.

A tankless RO system can be the best choice if you’re seeking for a reliable reverse osmosis water filter.

What is Reverse Osmosis?

Tap water is driven through a very thin membrane during the reverse osmosis (RO) water filtering process in order to remove impurities.

Reverse osmosis water filtration systems use a RO membrane together with a number of other water filters to purify your tap water by removing up to 99% of all sediment, chemicals, colors, and aromas.

Nobody likes to be concerned about environmental toxins, boil water signs, or corroded and outdated pipelines. All of these problems may be fixed with a water filter device before you fill your glass.

Tankless Efficiency

Reverse osmosis water filtering “wastes” tap water because some of the processed water, which contains all of the filtered pollutants, is flushed down the drain.

Reverse osmosis drinking water systems without tanks are incredibly effective because of their internal booster pumps and high-throughput filters. For every gallon of waste water, the RO systems on this page create 1 to 2 gallons of filtered drinking water.

This contrasts with conventional RO systems, which can waste up to 4 gallons of tap water in order to generate just 1 gallons of filtered water.

Additionally, since a booster pump keeps the pressure at its ideal level, you don’t need to worry about your tap water pressure.

The name of this RO system has a late-2000s vibe to it. The “i(Insert Product Name Here)” formula may no longer be used, but the technology that powers this gadget is still cutting-edge. To their credit, the RO system resembles one that Apple would create if they were to create one themselves. It has the appearance and feel of a high-end RO filtering system thanks to the controls, aesthetics, and few functions.

This RO system has recently upgraded technology that makes it possible to fill cups and water bottles faster than previously. For a straightforward tankless filtration system, its maximum distillation rate of 0.4 gallons per minute is impressive. Nearly all pollutants are eliminated during the filtering process, with the membrane removing 99% of them. Finally, the smart faucet provides codes for troubleshooting in the case of any issues and notifies you when filters need to be changed.

Frizzlife RO Filtration System

One of the main drawbacks of RO system water is that it has a mild acidity and, much worse, little to no minerals. Even healthy minerals that would have been beneficial to your health are eliminated by the membrane since it filters out all contaminants. The Frizzlife contains a remineralization filter that is attached to the main device to gently alkalinize the water in order to address this issue.

Alkalized water has health advantages and is superior to the water produced by conventional RO distillation techniques. Additionally, it has a low drain ratio of 1.5:1 and has no tank, so your kitchen and cabinets underneath will have plenty of room to spare. The LED display, which provides real-time information about your filter and notifies you when to change it, is arguably the greatest feature.

OASIS OSMOSIS HOME Filtration System

The good news is that this next RO system is also the cheapest one we’ve examined and has a ton of great features that make it well worth the money if the iSpring’s high price was your primary deciding factor. Due to its low drain rate and high water flow rate, this RO system claims to be up to 24% more efficient than conventional versions. In just 12 seconds, you can have a cup of filtered water at your disposal.

The technology eliminates all contaminants with a 0.0001um precision. Whatever is present will be filtered away during the distillation process, whether it be fluoride, metals, or limescale. Because of the way this system is built, you won’t need to set aside a lot of room for a tank under or next to your sink. You definitely receive your money’s worth for little under $300, especially if you utilize the system frequently for your hydration needs.

Is it Safe to Drink RO Water?

Reverse osmosis is a water filtration technology that uses a semipermeable membrane to filter impurities from water. The technology was originally introduced to make seawater more drinkable and reduce heavy metals in water. Now, it’s commonly used for home water filtration systems.

Reverse osmosis systems are highly effective for filtration because they eliminate a wide spectrum of contaminants from water. They filter out contaminants like bacteria, viruses, heavy metals, volatile organic compounds, fluorides, and hard minerals.

Reverse osmosis systems are great at what they do, but there’s a catch. The WHO says that the low mineral water produced by RO systems tends to negatively affect human health, especially after long-term consumption.

How is RO Water Harmful to Health

Since these reports, many homeowners who rely on reverse osmosis systems for clean drinking water have become concerned. People wonder if RO Water is really safe to drink and if it’s still a good investment. There are a lot of factors to consider before concluding on this.

Here we will discuss why RO water may be considered harmful. We’ll also weigh the pros against the cons to see if RO water is really worth it.

How is RO Water Harmful to Health?

Reverse osmosis removes a lot of impurities from water. Unfortunately, this includes a large percentage (90-99%) of beneficial minerals like calcium and magnesium. Based on several studies conducted by the WHO, demineralized/low mineral water is harmful to health. And according to WHO reports, the effects of drinking demineralized RO water start to show very quickly.

In several weeks or a few months, people who drink demineralized water may notice symptoms that suggest acute magnesium or calcium deficiency. Other complaints like cardiovascular disorders, muscle cramps, tiredness, and weakness also surface. Intake of low mineral water has also been associated with a higher risk of fracture in children, pregnancy disorders, and certain neurodegenerative diseases.

Demineralized water causes malnutrition and leaches away existing minerals in the body (meaning that minerals gotten from food the person eats will be urinated away).

Even when used for cooking, RO water leaches away important minerals from food.

Is RO Water Still a Good Option?

Although RO systems produce demineralized water, they still have some benefits. Reverse osmosis systems are one of the most effective filters available. If you choose to ditch RO filters, you may have to deal with contaminants like lead, arsenic, chlorine, bacteria, and high amounts of total dissolved solids (TDS) that come with tap water. Compared to demineralized water, these contaminants could lead to a longer list of health problems.

Reverse osmosis filters are a lifesaver in places with poor water quality. They make the water potable and prevent the spread of waterborne diseases.

Also, with a well-balanced diet, you’ll barely feel any effects of demineralized water. You can supplement some of the minerals missing from your drinking water with food. Ordinarily, water shouldn’t be your primary source of nutrients, so altering your diet to include more minerals and vitamins should sustain you.

But if you’re still worried about the demineralized water affecting your health, there are ways to go around it.

Some reverse osmosis filters have a remineralization stage where healthy minerals are added back into the water. Of course, the water will not contain the same amounts of minerals as regular water, but it’s better than having no minerals in the water at all. With some more minerals in your water, the adverse effects of RO water will reduce considerably.

Best Reverse Osmosis Filters

We listed mostly under sink filters since they are a more common type of RO filter. But if you prefer a RO filter with zero installation requirements, you can find at least 5 countertop RO filters that are just as effective.

We also tried to include filters with the remineralization feature since they are a better variety.

1. Home Master Artesian

Home Master is an under sink system with the remineralization feature. The filter adds beneficial minerals into the water at two different stages before finally dispensing it. It has easy-to-change filter cartridges and doesn’t come with a bulky filter housing. The system is also designed to reduce wastewater considerably.

2. iSpring RCC7AK

This filter is highly rated for its remineralization abilities. It works in 6 stages, with alkaline remineralization being the last stage. The alkaline filter needs to be changed twice a year, but the RO membrane can last up to 3 years before needing a change.

3. APEC Essence ROES-PH75

APEC essence also has a remineralization feature. It has a 6 stage filtration process, the last stage being an alkaline calcium filter which makes the water taste like bottled water. The filter is suitable for small cabinets. Its installation process is also simple and can be done without a plumber.

Reverse osmosis water may be deficient in a few minerals, but it’s still good to drink with the right precautions. If you have contaminants in your water, you should consider getting one. All that matters is that you take the necessary precautions to ensure that you don’t lack the nutrients you need to stay healthy.
