Reverse osmosis is a process of filtration that uses pressure to force water molecules through a semi-permeable membrane, leaving behind larger particles and contaminants. This process can be beneficial for reducing the number of contaminants in drinking water, but there are also some drawbacks.
One of the main pros of reverse osmosis is that it can remove a wide range of contaminants, including lead, chlorine, and other common pollutants. The process also removes most nitrates and phosphates, which can be beneficial in areas where those chemicals are found in high concentrations. Reverse osmosis systems are relatively inexpensive to install, making them an affordable option for many households.
What Is Reverse Osmosis?
Reverse osmosis (RO) is a process of purifying water by forcing it through a semi-permeable membrane. The pores in the membrane are small enough to allow only purified water molecules to pass through while blocking out salts, bacteria and other contaminants. This process produces water that is extremely pure and ideal for drinking.
How Does Reverse Osmosis Water Filtration Work?
Reverse osmosis water filtration works by using a series of filters and membranes that purify the water. It forces water molecules through a semi-permeable membrane, while larger contaminants are blocked, leaving behind clean and purified drinking water. This process is often referred to as hyperfiltration or ultrafiltration.
Pros Of Reverse Osmosis
- Exceptional Water Quality: Reverse osmosis is one of the most effective methods for filtering out impurities from water. This process results in clean, healthy and taste-free drinking water with all harmful contaminants removed.
Exceptional Water Quality - Removes Many Contaminants: One of the greatest benefits of reverse osmosis is its effectiveness in removing a variety of contaminants from water.

It also removes up to 99% of dissolved solids which can lead to better tasting water with fewer mineral deposits.
Removes Many Contaminants - Know Where Your Water Is Coming From: One of the benefits of reverse osmosis is that it can be used to filter out contaminants from almost any source. Whether your water comes from a public utility, well or other source, reverse osmosis can help ensure that you are getting safe and clean drinking water free from pollutants.
- Removes Chlorine and Fluoride: Reverse osmosis can be an effective way to remove chlorine and fluoride from water. This is beneficial in many areas of the world where naturally occurring levels of these two chemicals are too high for safe drinking water. Because reverse osmosis removes these contaminants, it provides access to healthy drinking water in such areas.
Removes Chlorine and Fluoride with RO - Better Tasting Water: Many people enjoy the taste of reverse osmosis water because it is free from many contaminants, such as chlorine. The process also removes minerals like calcium, magnesium and potassium that can give water an unpleasant taste.
- Better Tasting Food: One of the main advantages of reverse osmosis is that it can improve the taste of food and drinks. This is because it removes contaminants, including chlorine and other minerals, which can give water an unpleasant taste. By removing these substances, you will be left with a cleaner and tastier drinking experience.
- Non-Electric Water Filtering: Reverse osmosis (RO) is a non-electric method of water filtration and purification that uses pressure to force water through a semipermeable membrane. This process removes large particles and impurities from the water, leaving it free from chlorine, lead, nitrates, and other contaminants. RO systems are typically installed on one’s main water line and can filter out impurities from all the water entering one’s home.
Non-Electric Water Filtering - Minimal Maintenance: Reverse osmosis systems require less maintenance than other water filtration systems. Since the membrane filters out most contaminants, all that is needed to maintain the system is replacing the filter cartridges and sanitizing the membrane every so often. This makes reverse osmosis an ideal option for busy households or those with limited time to devote to maintenance.
- Saves You Money: Installing a reverse osmosis system in your home can save you money in the long run, as it eliminates the need to purchase bottled water. In addition, most systems come with filters that should be changed every few months to keep the system working efficiently — and those filter costs are typically less than what you’d spend on cases of bottled water.
Saves You Money - Convenience: Reverse osmosis is a highly convenient way to get clean drinking water. It requires little maintenance and can be easily installed under your sink or in other areas of the home. This makes it an ideal option for households that don’t want to bother with purchasing and constantly restocking bottles of filtered water.
- Odor-Free Water: Reverse osmosis can provide you with odor-free water because it filters out the organic compounds and chemicals that cause odors. This type of filtration from reverse osmosis systems can also help reduce bad tastes like chlorine, salt, and sulfur in your drinking water.
Odor-Free Water - No Water Jugs To Change: One of the best advantages of reverse osmosis is that it eliminates the need to constantly change out water jugs. With traditional methods, you would have to buy and assemble your own filter system or buy costly replacement cartridges. With reverse osmosis, you only need to keep up with maintenance and occasional filter changes.
- No Expensive Service Calls: Reverse osmosis systems are easy to maintain and require minimal servicing. The only regular maintenance necessary is the replacement of filters. Furthermore, you don’t need to hire a technician for this job as the instructions on how to replace the filters can easily be found online or in the manual that comes with your unit. As such, you can save money on expensive service calls.
The Cons Of Reverse Osmosis
- Clogging Filters: One of the biggest cons or drawbacks to using reverse osmosis is that it requires frequent filter changes in order to avoid clogging. The sheer amount of sediment and impurities that can be passed through with this process can quickly cause filters and other components to become clogged, reducing efficiency and requiring more frequent maintenance in order to keep the system running properly.
Clogging Filters - Initial Investment: Reverse osmosis systems require a higher initial investment than other water filtration methods, as they involve more complex technology. However, the upfront cost can be offset in the long run due to its efficiency and durability.
- Regular Filter Replacement: One of the biggest pros when it comes to reverse osmosis is that filter replacement is relatively easy and inexpensive. Depending on the type of water, filters may need to be replaced every 6-12 months or every 500 gallons processed. Some models require minimal maintenance, but most will come with instructions for replacing filters as needed. Additionally, some brands offer subscription services that deliver new filters directly to your door each month, making filter replacement even easier.
Regular Filter Replacement - Slow Water Production: One of the most significant downsides of reverse osmosis is the slow production rate. This process can take anywhere from 30 minutes to two hours to produce a gallon of water, making it an impractical solution for large-scale operations. In addition, this slow production rate means that energy consumption is higher than other filtration methods.
Slow Water Production of RO - Removes Beneficial Minerals: Reverse osmosis systems are able to remove some of the beneficial minerals such as calcium and magnesium that can be found in drinking water. This means that while the water may be free from impurities, it can also lack important electrolytes and other nutrients that are beneficial for our health.
- RO Water Is Too Pure: One of the primary disadvantages of reverse osmosis is that the resulting water is too pure. This means there are no minerals in it, and it can sometimes taste flat. In addition, some people worry that removing all these minerals can have a negative effect on their health.
FAQs
Will not changing reverse osmosis filters often enough affect the life of an RO system?
Yes, not replacing the filters as often as recommended can reduce the life of an RO system. Depending on how hard your water is and how much sediment it contains, you may need to replace filters more frequently than suggested by the manufacturer. In addition, if too much dirt or sediment collects in the membrane surface of the RO system, it could reduce its effectiveness and lead to more frequent filter replacements.
Is RO water banned in Europe?
No, reverse osmosis (RO) water is not banned in Europe. RO has been used for many years in the European Union (EU), and its use continues to be permitted in member states. The EU provided directives on drinking water quality standards in its “Drinking Water Directive” document of 1998, which includes some requirements related to the treatment of water with RO. The directive recommends that all EU member states strive to meet these quality standards.
