Considerations When Buying A Reverse Osmosis System

Considerations When Buying A Reverse Osmosis System

A common question that first-time buyers usually ask is how to choose a reverse osmosis (RO) system. Obviously, you can’t just buy any RO system because you need to consider a lot of factors. You need to carefully think about all these so that you can get the most suitable product for you. And to help you with that, below are some considerations in searching for that perfect RO system.


Choosing an RO system means you need to have a budget. How much are you willing to spend on a product like this? Prices really do vary as some are available at 150 dollars while others cost a thousand bucks.

However, most RO systems are sold at around 250 to 500 dollars. Normally, those sold at a higher price have a very good reason for it. It can be because of their additional stages in filtering water or capacity to filter bigger water quantities at once.

Some even have an auto flash as an extra feature. There are also higher-end RO systems that can add valuable nutrients to the water after removing the harmful contaminants to improve the taste and the overall quality of the water.

On the other, cheaper RO systems may get you delighted of their more affordable price, but disappoint you of their poor quality materials that break or leak easily. The middle-range products may meet you halfway with better performance, but just without the fancy add-ons.

Water Amount

This talks about the number of gallons that an RO system can handle a day. It can range from 50 to 80 to 100 gallons for most standard sizes.

A 50-gallon system can already work for you if you have quite a small household. If you then have a larger one, you may opt for bigger sizes since you have the tendency of using so much water.


This is an essential consideration because you need to know if the RO system you are planning to purchase will fit where you intend to place it. Yes, you may have bought the perfect product, but if it does not fit on the counter or under your kitchen sink, you will still end up with a problem.

Thus, think about the available space you have at home and see if an RO system that performs well can fit there. Check the dimensions of the item you are eyeing so you have an idea if it is a perfect fit.


Sometimes, you read the product description that there are a number of stages that an RO system undergoes to purify water. This actually means the number of filters that is utilized by the system in removing toxins from the water.

For instance, a system saying it has four stages of water purification refers to 1) a sediment filter to remove sand and dirt, 2) a carbon filter to eliminate chlorine and other contaminants, 3) an RO membrane to assist in filtering any chemicals that may have been left behind, and 4) a post-carbon filter to handle any impurities that still remain. For other RO systems, they have five to six stages that include adding minerals to the water for improved taste.


RO systems may give you clean and healthy water to drink, but normally, they also use a lot of water that turns into waste. Most systems only regain an estimated 5 to 15 percent of the filtered water.

Generally, using extra water is merely a basic effect to create cleaner drinking water. But the good news is there are some RO systems designed to lessen water waste by giving it another purpose such as water for laundry or dishwashing. If it is alright for you to use water containing more sediments and chemicals for other uses at home, you may opt for zero-waste RO systems.

Easy Installation

Hiring a professional to install RO systems also means paying for that person, which again means an additional expense. If you can have a system that comes with simple yet clear instructions on installing the product on your own, then that is a huge plus for considering buying that RO system.

Be a wise customer and buy what will be in your best interest. Follow the steps above and you will surely end on the right path.
