Buying Guide

What is a Reverse Osmosis Water Filtration System?

Reverse Osmosis is a water purification process that uses a semipermeable membrane to purify water and remove chemical toxins and contaminants from it. Unfiltered water passes through the fine pores of the membrane at high pressure, and the contaminants are left behind in the wastewater.

Furthermore, it uses pre-filters for removing large mould particles so that they don’t clog the membrane. Since this process is so thorough, it also removes the healthy minerals found in natural water, which leaves the water with a bland taste. To resolve this issue, an RO filter system offers a remineralization stage in which minerals such as calcium and magnesium are added back to the filtered water.

Things to Consider When Buying An RO System

A reverse osmosis filtration system can provide healthy drinking water with no contaminants, which can keep you safe from water-borne diseases. That is why such filter systems are becoming more and more popular, and with the increase in demand, there are so many options available on the market.

But before buying an RO system, it is essential to educate yourself about its important aspects, so you get the most efficient system. You can find these systems with both affordable and expensive price tags. So by keeping the budget in mind as well as the health benefits, you can find a good water purification system. We have explained these aspects below to help make your decision easier.

Installation and Size

A reverse osmosis filter system usually comes with a faucet and a storage tank that can store the water. It is important to make sure that you have enough space under the countertop so you can install the system and place the tank. You will need to drill a hole in the countertop for the water pipe coming out of the system.

These systems are usually easy to install especially if you have some experience with DIY work. You can watch YouTube tutorials and follow the instruction manual given with the system for installing the unit. In contrast, you can also get the tankless RO system that does not come with a storage tank and is far easier to install.

Waste Water to Filtered Water Ratio

It is one of the most significant aspects of an RO system as it will tell you how much water is wasted for purifying one gallon of water. The ideal ratio is 1:1, meaning that for providing one gallon of filtered water, only one gallon of water is wasted. But there are systems that waste 75% of water. It is best to avoid such systems as you will be wasting a large amount of water.

Water Pressure

The greater the water pressure, the greater will be the water output, and less water will be wasted. There are ways to increase the water pressure, and one way is to use a permeate pump. As a result, the water circulates at high pressure, and less water is wasted.

Energy Efficient

Most of the reverse osmosis systems do not require electric power to run, which makes them energy efficient. In contrast, some RO systems use Ultraviolet light to kill germs and bacteria, so these run on electricity. You can go for either of these systems depending on your budget.


It is an important stage in the purification process and uses an alkaline filter to improve the taste of water. Essential minerals such as calcium and magnesium are lost when the water passes through the RO membrane, and this water may not be too healthy for your immune system. The remineralization stage adds these minerals to the filtered water to make it healthy. So always look for an RO system that includes this stage.

Final Thoughts

Reverse osmosis is an efficient process of filtering water that removes 99% of harmful metal and contaminants from water. It is ideal to invest in a quality RO system so you can always have healthy water to drink. With the increasing demand, companies are manufacturing advanced RO systems that waste less water. Our top picks amongst the best reverse osmosis systems for home use are given below.

So that is all for the best reverse osmosis systems for home use in 2024. We have reviewed RO systems belonging to the most trusted brands, so check them out.

Let us answer some of the most frequently asked questions.

Do reverse osmosis systems waste a lot of water?

A typical ro system for aquarium wastes about 4 gallons of water to produce one gallon. So if you need 20 gallons in a week, it will waste around 80 gallons of water, making it about 25% efficient.

How can I make my reverse osmosis more efficient?

You can improve the efficiency of a reverse osmosis system by using a permeate pump which reduces the water sent to drain against the clean water produced. Basically, a permeate pump enables the ro system to use less water for better performance.

How long does it take to fill a reverse osmosis tank?

It generally takes about two to four hours to fill a 2.8 gallon reverse osmosis tank.
