Buying Guide for the Reverse Osmosis System

Installing a best reverse osmosis system requires great investment. Therefore you need to be wary before spending your money on any product. There are hundreds of brands that are manufacturing this filtration plant. The reverse osmosis system comes in various sizes and capacities. What size and capacity of the filtration system you won’t depend on your requirements. Generally, there are two types of reverse osmosis systems. To make things more comprehensible, we will discuss the types, then list the essential features to consider.

Types of Reverse Osmosis System

The Reverse osmosis filtration plant comes in two different types that are countertop and under-counter reverse osmosis systems. What option you go for depends upon your personal preference and need. Let’s briefly discuss these types of reverse osmosis systems. After that, we shall proceed to the important features to consider before buying an RO water filter system.

Countertop Reverse Osmosis System

This type is the most compact reverse osmosis system you will come across. A countertop is portable and doesn’t require a lot of kitchen space. Moreover, this type does not require complex installation. All you need to do is place it on the countertop or on the floor. You can also take this type of reverse osmosis system whenever you want if you plan to move out,

Under-Counter Reverse Osmosis System

The next type is the under-counter reverse osmosis system that is the most widespread reverse osmosis system you will see. This type requires a specialized installation and can filter large quantities of water. Moreover, this type also produces large quantities of wastewater, in addition to that, it is more of a permanent option, and it’s very efficient. Lastly, this type of reverse osmosis system can filter water quickly.


The first and foremost thing to consider is the budget. The market is flooded with inexpensive as well as expensive reverse osmosis filtration systems. You can always get the cheap ones but bear in mind that you will get fewer features. Compared to that, a higher-end reverse osmosis system exhibits extra features. In addition to that, what you will be getting is a filtration plant made with industry-leading material. If you are spending so much on your water filtration plant, it should be worth all your money. Besides, the inexpensive ones are also good and work well. If your requirement doesn’t need spending a lot, you can always go for those that cost less.

Available Space

Another important consideration you need to make before buying a reverse osmosis system is the available space. The space you have to allot to this filtration system is directly proportional to the size of it. If you are getting it to install it under the washbasin or on the countertop, you need to take the correct measurements. Getting a big reverse osmosis plant will take a lot of space or might not fit under the sink. So it is necessary to think twice about the size of the filtration system.


The next thing you need to ponder is the amount of water your water filtration plant can filter. Reverse osmosis systems come with different capacities. What capacity you buy depends upon your personal requirement. Typically, you will see a reverse osmosis system with 50, 80, or 100 gallons filtration capacity per day. The capacity of this system depends on how large or small of a household you have. If you have a small family, then a 50 gallons capacity reverse osmosis system is best for you. However, if you have a large family, then you should consider larger capacity reverse osmosis systems.

See How Well the Reverse Osmosis System Works

At the end of the day, all you want is clean and great tasting water to drink. For that matter, your whole filtration system ought to perform well. Make sure your reverse osmosis system has at least four stages of filtering water. These four stages include sediment filter, carbon filter, reverse osmosis membrane, and a pre-carbon filter. These filters will very effectively remove large particles, chemicals, and some other impurities.

By the end of all the processes, you will get clean water with amazing taste. However, a few more stages of filtration aren’t bad. If you are very much concerned about the quality of water you are consuming, you can always opt for the reverse osmosis system with additional filters. The extra filters ensure that the water you are drinking is free from all the deleterious impurities.

Easy Installing and Usage

Choosing a product that has easy installation is a win-win situation. You wouldn’t want to spend extra dollars on installing your reverse osmosis system. Instead of selecting the product that needs to be installed by the professionals, go for the one that has an effortless installation and works great. Besides, you need a filtration system that has low maintenance. Go for the one that is straightforward to use on a daily routine. If you have a busy schedule and can’t keep up with its maintenance, consider buying one that requires changing filters once in one year.

You should also consider that your reverse osmosis system comes with a good warranty. You don’t want your filtration plant to stop working or break easily at the end of the day.

Water Waste

Now the last thing you shouldn’t overlook is the amount of wastewater your reverse osmosis system is creating. Unfortunately, a reverse osmosis system creates a lot of wastewater in the process of cleaning water. On the bright side, you can use wastewater for other purposes such as laundry, washing, or doing the dishes. If you are okay with using the wastewater, there are fewer chances of the water being wasted and unused.
