Buyer’s Guide: How to Choose the Best Tankless Reverse Osmosis System?

Are reverse osmosis good to buy? Yes, it’s good. But It is crucial to consider the following listed factors to opt for the best tankless reverse osmosis systems. After reading the tankless system reviews, scroll down to the buyer’s guide you would ever need!

Water Source

The source of your water is essential knowledge when buying a reverse osmosis water filtration system. Water from different sources has different contaminants. For example, well water has dust and sediment. Similarly, the city supply might have other contaminants.

First, you must test your water to see what contaminants it contains, as different systems eliminate different impurities. 

You can read Tankless RO reviews written above to make a better decision. Reverse osmosis membranes effectively remove as little as possible contaminants from the drinking water. 

Certification

NSF/ANSI certification of the RO systems and components is necessary for their optimum function. Certified reverse osmosis filtration systems have high-grade material, which ensures no cross-contamination of your drinking water. Most under-sink and countertop reverse osmosis water filters are certified, but you should always visit their website to confirm!

Storage Capacity

After reverse osmosis filtering, the filtered water requires storage in a storage tank. Since the reverse osmosis filtration process is considerably slow, it is always safe to have a storage tank for immediate water use. Some RO filter tanks can store up to 75 gallons of water, but one of the cons of buying a tank-attached countertop reverse osmosis water system is that it occupies a lot of space. Another one is to cause the microorganism in the re-filtered water. 

Besides this, you can always opt for tankless RO systems with a high GDP rate, such as KFlow tankless design.  

Water Usage

Even the best reverse osmosis filtration systems waste a certain amount of water. Depending on your daily water usage, you should opt for systems with a low wastewater ratio if you live in an area with water scarcity. Countertop reverse osmosis water filters have a high wastewater ratio as most of these filters do not have attached tanks.

Express water reverse osmosis systems have a standard wastewater-to-filtered water ratio.

Water Pressure

For an RO system to work, it needs a water pressure of at least 50 pounds per square inch (PSI). In many homes, the water pressure is 30 to 80 PSI. This high pressure is needed to push the water through the various filters and maintain adequate pressure at the tap. 

The RO booster pump increases the water pressure by up to 80 psi for homes with insufficient force. Even homes that operate on the standard city water pressure of 60 psi can benefit from a pump, as an RO system will run better at 80 psi or higher. A tankless RO filter system cannot work efficiently if your water pressure is not high.

Replacement Filters

Most RO systems last 10-15 years, while the filter cartridges last 12-24 months. The replacement of filters also depends on the quality of your tap water. If you have more dirt and impurities in your tap water, you will replace your filters frequently.

Easy installation is the most important thing to consider in replacing your filters. Sometimes replacement filters need to be cleaned thoroughly before putting them back. Some filters are easy to install and swap, making changing filters much more manageable.

Remineralization

Even though tankless systems are efficient, they do have their limitations. Mainly, you can’t add UV filters to help against living organisms in water or alkaline filters to help remineralize your water. You’ll need a more extensive system that will use a tank for those types of filters more than likely.

You will need to add additional alkaline filters that can fit under your sink because tankless RO filters don’t take much room; there is enough space for other additional filters.

Also, check out the best alkaline water filter pitchers list.

UV Sterilizer

A UV sterilizer treats water with germs and micro bacteria with UV light. UV radiation’s wavelength alters these microorganisms’ DNA, so they don’t reproduce and make your water impure.

UV disinfection treats water for 

  • Cryptosporidium
  • Giardia
  • Dysentery bacilli
  • Salmonella
  • Mycobacterium tuberculosis
  • Streptococcus
  • E. coli
  • Hepatitis B
  • Cholera
  • Algae
  • Fungi
  • Some viruses

A tankless reverse osmosis water filter does not come with a UV filter, so installing a UV sterilizer with your water filter is essential.

Maintenance And Installation

Tankless drinking water filtration systems are easier to install and maintain under your sink because almost everything is contained in one case. There are fewer connections and fewer components.

Also, tankless water filters are simple to replace without shutting off any water lines, using extra tools, or having difficult access angles.

Most tankless reverse osmosis systems mentioned have easy twists and replace filters right before the case. There will be no water leakage while you return the filters in the filter system.

Information You Need to Know: What is a Tankless Reverse Osmosis Water System?

When it comes to the “Tankless Reverse Osmosis System is a standard system without having a tank.” You need to install this system at the point of use, press the button and turn it on. Tankless systems are fast water-producing devices that take minimum water to fill a glass of pure water. They easily fit beneath the sink and cause readily available water for use. Also, they don’t require high maintenance, installation and space like other traditional systems. 

The tankless RO system is a good choice for apartments or renters, who can take it anywhere they want. These filters are easier to maintain, portable, highly compact, and produce healthy water with an improved taste. On the other side, When you use a standard reverse osmosis water filter, the tank takes extra time to fill. Thus, the tankless RO water filter system is a hassle-free device for getting water instantly.

Types of Tankless Reverse Osmosis Water Filters

  1. Horizontal (sitting) tankless RO system
  2. Vertical (standing) tankless RO system

Two types of filter cartridges are available for this kind of setting.

  • Front-loaded cartridges are mainly used in horizontal RO systems
  • Top-loaded filter cartridges are found primarily in vertical RO systems.

Tankless RO filter systems are mostly known to give unlimited reverse osmosis water much faster than other reverse osmosis water filtration systems. Water is directly passed onto the reverse osmosis filters and then flows in the faucet, meaning more gallons of filtered water daily.

Reverse osmosis is the technology used in this system that works as a semipermeable membrane removing all the contaminants that are harmful to health. Reverse osmosis water filtration systems deduct TDS (Total Dissolved Solids) Fluoride, Chlorine, Heavy metals such as Lead, Arsenic, Cadmium, and Mercury, VOCs, Herbicides and Pesticides.

You can click to learn what reverse osmosis removes from your drinking water. 

How Does Tankless Reverse Osmosis Filter Work?

A tankless or any other reverse osmosis filter system works as Pre and Post filters which are described below:

Pre-Filters

Sediment Removal FiltersReverse osmosis membrane
Before passing through a RO membrane, a sediment filter work as a first filter that removes all the sediments, sand, slit and rust to improve the water quality. After filtering sediments, the reverse osmosis membrane work as the central functional part of filtration systems. It is made to eliminate microscopic organisms up to 0.001 microns. The tiny holes in the membrane allow water molecules to pass through, whereas the larger contaminants stay behind. This technique is effective in removing 99.99% of pollutants in water. The removed impurities remain behind, and only clean and filtered water is allowed to pass through. The impure water has a separate pipe, so contaminants cannot enter your water again.

Post-Filters

Remineralization and UV sterilizers are considered post-filters after RO filtration. These filters are optional and depend upon your budget.

Remineralization FilterUV Filtration,
The remineralizing filter work as a post-filter, makes the water alkaline in nature and adds the essential minerals back into the water. These minerals include potassium, calcium, and magnesium. Reverse osmosis filtration systems make the water acidic and remove all the vital minerals from water; hence some people use remineralization to solve this problem.
UV sterilizers use UV radiation to kill pathogens and germs from the water. The purpose of installing a UV sterilizer is to prevent bacterial growth in water and keep your drinking water microorganism-free.

Advantages of Tankless Reverse Osmosis System

There are various advantages of using a tankless reverse osmosis system which is mentioned below:

  • Get Clean and Pure Water Instantly!

You don’t need to wait to stand around the tank to fill. You must press the button and fill the glass with water in a few seconds. It is the best way to save your money on gallons and a perfect solution!

Then this guide is for you. The tankless system will help you save up to 70% of your kitchen space. It would help if you went for it. 

  • Say Buy To Bottle Water!

You can get bottled water from the nearest store. But think it’s a good use of money and time? It could be exhausting and impractical. So you don’t have to pay for your waste on plastic bottles. I suggest a long-term investment that will be worth it for years. Tankless reverse osmosis filters are for you. It can provide instant clean, and pure water. 

  • A Short-Term Maintainance!

The tankless systems can cause secondary pollution. Plus, you need to maintain it regularly. The reason behind this is the chance of the building up of microorganisms. But the tankless system requires less maintenance and doesn’t re-infect the filtered water. 

Also, if you keep the purified water for the long term in the tank, it changes the taste. Thus, the tankless system doesn’t alter the taste.
