Reverse osmosis (RO) water filtration is recognized as the most convenient and efficient drinking water treatment method on the market. It works at the molecular level, removing up to 99% of common and dangerous contaminants in water such as chemicals, bacteria, metals, dirt and other organic compounds.
Like any type of water filter, reverse osmosis systems have many advantages and limitations. Before installing reverse osmosis water filtration systems, it is important to understand how they work and where you can place them in your home to ensure compatibility and optimal performance.
This guide shares the top 10 reverse osmosis water filters on the market in 2022.

Reverse osmosis water filters can be expensive. The amount of water you need to filter each day can affect the price of the filter you buy. (Large homes and/or lots of water = big filtration systems.) If you know you don’t need many gallons per day (GPD), you can lower your overall costs – initially and over time – by using a reverse osmosis system with a low GPD filter. .
Reverse osmosis systems rely on water pressure to function, so make sure your home can handle it before purchasing a filter. Optimal reverse osmosis flow requires at least 40-60 psi, ideally at least 50 psi. Low water pressure reduces the flow of water from your faucet, resulting in more waste and reduced filtration efficiency.
The amount of water you use will determine the semi-permeable membrane capacity or gallons per day (GPD) of the device you need. The higher the GPD value, the higher the membrane yield. If you intend to use less water per day, a lower capacity membrane is a better choice as it will last longer and have less downtime.
Your reverse osmosis system needs to tell you what types of contaminants it can filter and how well it is producing clean, great tasting water. In addition, you need to find out how much wastewater they produce in the process and how the system handles it.
Maintaining the efficiency of your reverse osmosis filter means replacing the filter as needed, and filter replacement costs can vary greatly. Before you buy, look at how easy it is to replace these filters (and whether it costs the labor of a professional) as well as the cost of individual filters to make sure you can keep up with the maintenance of your reverse osmosis filtration system. .
Reverse osmosis systems slow down water and water speed varies greatly between systems. It takes time to produce highly filtered water with low levels of contaminants. You’ll want to buy a system with a storage tank that will hold as much water as you need for daily use so you don’t have to wait for it to clear. It’s also worth paying attention to how quiet your reverse osmosis system is to avoid loud rattling when filtering water, even when you’re not using it.
The process of installing a reverse osmosis water filter is very important to ensure that your filter works properly and safely. If you do not know all the components of the system and are not very confident in your skills, it is best to entrust this to a professional plumber. Here is a simplified process step:
5. Let the system generate a full tank of reverse osmosis water. This may take 2-3 hours, depending on how much water you need to filter.
To determine this ranking of the best reverse osmosis water filters, the Forbes homepage editors analyzed third-party data for over 30 products. The rating of each product is determined by evaluating various indicators, including:
Reverse osmosis is an effective water filtration method that removes a wide variety of contaminants and impurities and is often considered the best filter for drinking water. As with all types of water filters, there are situations where they are a more effective choice, and there are situations where a different type of water filter may give better results.
Some common contaminants that can pass through reverse osmosis filters include certain types of chlorine and dissolved gases, pesticides, herbicides, fungicides, and organic compounds. If these problems persist after identifying contaminants in the water with a water test kit, a different type of filter may improve your water quality.
Yes, reverse osmosis filtration can help filter out and remove many of the contaminants found in groundwater, making it safer to drink. Whole house reverse osmosis water filtration systems are more common in rural homes that depend on well water.
Osmosis and reverse osmosis have similarities in that they both remove solutes from water, but also have key differences. Osmosis is a natural process in which water molecules diffuse across a semi-permeable membrane from a place of high water concentration to a place of low water concentration. In reverse osmosis, water passes through a semi-permeable membrane under additional pressure in the direction opposite to natural osmosis.
The cost of a whole house reverse osmosis system will vary depending on several factors, but is closely related to the amount of water that needs to be produced each day, as well as the amount of pre-filtration equipment. You can expect to pay between $12,000 and $18,000 for an installation that includes labor and materials.
Reverse osmosis filtration system is the best choice for drinking water. Several stages of the filtration process can remove up to 99% of contaminants in the water.
