How Much Does a Countertop Reverse Osmosis System Cost?
Countertop reverse osmosis systems are not cheap devices. These devices cost anything from 70 USD to 600 USD. The high end devices are near the 600 USD mark. Such devices have features such as a modern look, a touchscreen display and extreme portability. An example of such as device is Frizzlife Reverse Osmosis Water Filtration System.

Types of Countertop Reverse Osmosis Systems
The reverse osmosis systems use two types of reverse osmosis membranes:
Thin Film Composite Membrane
These are the countertop reverse osmosis systems that use thin film composite membranes. These are constructed in the form of a film from two or more layered materials. They can be considered as a molecular sieve. These have a high rejection of undesired materials such as salts, have a high filtration rate and have a good mechanical strength. They can reject up to 98% of standard contaminants and are less susceptible to organic fouling. They can only treat chlorine free water.
Cellulose Triacetate Membrane
These are the countertop reverse osmosis systems that use cellulose triacetate membranes. These are produced from cellulose and a source of acetate esters. This type of membrane can treat water which has chlorine in it. It is more susceptible to fouling from bacteria and rejects up to 93% of standard contaminants.
Why Should You Buy a Countertop Reverse Osmosis System?
Water from the tap comes with a lot of impurities. These vary from dissolved solids to viruses, and sometimes dangerous chemicals. A reverse osmosis system will enable you to clean your water and give you peace of mind as you are guaranteed that your water is relatively safe to drink.
These water purifying devices are very easy to carry around. Some of the countertop reverse osmosis systems come in a similar shape to a coffee maker and operate in a similar manner. This means that you can carry them around quite easily.
Easy to Install and Use
The countertop reverse osmosis systems are usually easy to install and use. This means that you do not need to hire a professional to install them. Some offer a “tools free” installation. This means that you will not need to buy any special tools to set up the countertop reverse osmosis system.
Factors to Consider When Buying a Countertop Reverse Osmosis System
Ease of Installation
When buying countertop reverse osmosis systems, this is an important feature to consider. You do not want to buy a device that needs you to hire professionals to install and use it. The countertop reverse osmosis system you choose must be very easy to install, and it is best to go for a tools-free device. This means that you will not need to have any specialized tools to setup the device.
This is another important aspect that needs to be given a thorough analysis. You need to have a look at how much water the countertop reverse osmosis system can process in a given period of time. This will help you to choose the device that will be able to produce the most amount of water that meets your needs. If you have a large family, you are going to need a device that produces a lot more water than if you have a small family.
When purchasing any electronic or electromechanical device, it is best to consider the warranty offered by the manufacturer. The warranty gives a good indication of the manufacturer’s confidence in his or her product. As a general rule of the thumb, products with longer warranties are made from better materials and last much longer than similar products that have shorter warranties. This is an important feature to consider when purchasing countertop reverse osmosis systems because these devices are pretty expensive.
All the countertop reverse osmosis systems use filters. These are used to help purify the water present. Before choosing a device to add to your home, you need to check how much replacement filters cost. If you find the replacement filters to be expensive, then try to go for a device that has cheaper filters. This means that it could make sense to go for a more expensive device. The returns will come after purchasing filters over a long period of time e.g. 3 years.
Where exactly do you want the countertop reverse osmosis system to be placed? If you want to place it in your office, or if you want it to look good in any environment that you use it in, you need to choose a device that looks modern. There are very good looking osmosis systems in the market that will blend into virtually any environment that you put them into. Some look so good that they actually end up enhancing the environment that you put them into.
What is a Countertop Reverse Osmosis System?
A countertop reverse osmosis system is a water purification system that removes contaminants from feed water when pressure forces it through a semi-permeable membrane and it produces clean drinking water. These systems are portable and can be placed on a flat surface such as a counter, hence the name countertop reverse osmosis systems.
How Does a Countertop Reverse Osmosis System Work?
These devices are meant for water filtration. In every water filtration system, the objective is to put in unclean water and get clean water. In reverse osmosis, the water that needs to be filtered first goes through a set of filters. These are usually carbon and sediment filters. These remove sediment and chlorine that could clog or damage the membrane. After that, water is forced through a semi-permeable membrane. By semi-permeable, we mean that there are tiny perforations that block contaminants but allow water molecules to pass through.
The water flows from the side of the membrane which is concentrated with contaminants to the side of the membrane that has fewer contaminants. As you know, in osmosis, molecules move from a region of higher concentration to a region of lower concentration. The water molecules therefore move to the less contaminated region which is on the other side of the membrane. As you may have realized, there will be a moment when there will be a high concentration of relatively clean water on one side and contaminated water on the other side. The principle of osmosis would then say that the contaminants will move from a region of a high concentration to a region of low concentration – the side with the clean water. Reverse osmosis, however, blocks contaminants from entering the less concentrated side of the membrane.
After the water exits the membrane, the water flows to a storage tank where the water is held until needed. Such tanks ensure that when you turn on the faucet, you instantly get a full glass of water. When a person needs to drink water, he or she turns on the drinking water faucet. When this occurs, the water comes out of the storage tank. It passes through a post filter to polish the water. This is usually a carbon filter. After this, you get yourself a nice cup of fresh water.
Countertop Reverse Osmosis System FAQs
Are the Filters Replaceable?
Most of the countertop reverse osmosis systems come with a replaceable filter. Most of these filters are very easy to install. You just insert and twist the filter and you are good to go.
Do these Systems Consume A Lot of Power?
In most cases, no. A typical countertop reverse osmosis system consumes just 30 watts. That is the amount of power consumed by a typical lightbulb
Can I Test the Performance of the Filter with a TDS Meter?
Not really. TDS is a measure of total dissolved solids – the bulk of which are calcium and magnesium minerals, which this filter leaves intact. As a result very little, if any, change in TDS is to be expected. A better option is to use chlorine test strips, and view that result as a surrogate indicator for the filter’s overall performance.
How Long do the Filters Last?
These components usually last for quite a while. They can last for anything from 6 months to 1 year. As a general rule of the thumb, the more water you use, the quicker you need to replace the filters.
Which Tools do I Need to Install It?
You do not need to have any tools at all to install most of the countertop reverse osmosis systems. Most are tool free. This means that all you need to do is to plug the device into an electrical outlet after filling it with water and you are good to go.
