Reverse Osmosis Water: Pros & Cons

Reverse osmosis (RO) water purification systems have gained popularity for their ability to produce clean and purified drinking water. Reverse osmosis (RO) water is a type of purified water produced through a filtration process known as reverse osmosis. This method involves removing impurities and contaminants from water by pushing it through a semi-permeable membrane, effectively separating clean water molecules from dissolved solids, particles, and other contaminants.

However, like any water treatment method, RO systems have both advantages and disadvantages that homeowners should consider before making a decision. Here, experts from Local Plumber will delve into the pros and cons of reverse osmosis water, offering insights to help homeowners make informed choices about their water treatment needs.

Production Process:

Reverse osmosis water is produced through a multi-stage filtration process that typically includes the following steps:

• Pre-filtration: Water passes through pre-filters to remove larger particles, sediment, and debris.


• Reverse Osmosis: Pressurized water is forced through a semi-permeable membrane, which allows only water molecules to pass through while blocking contaminants.


• Post-filtration: The purified water undergoes additional filtration to remove any remaining impurities and improve taste and quality.


• Storage and Distribution: The purified water is stored in a holding tank and distributed through a faucet or dispenser for drinking and cooking.

Pros of Reverse Osmosis Water:

Removes Contaminants:

One of the primary advantages of reverse osmosis water is its ability to effectively remove a wide range of contaminants from drinking water. RO systems can eliminate impurities such as dissolved minerals, heavy metals, chemicals, bacteria, and viruses, providing clean and safe drinking water for your household.

Improved Taste and Odor:

By removing impurities and contaminants, reverse osmosis water often tastes and smells better than untreated tap water. Many homeowners prefer the crisp and clean taste of RO water, which lacks the metallic or chlorine-like flavors commonly found in untreated water.

Reduces Sodium Content:

RO water can be beneficial for individuals on low-sodium diets or those with certain health conditions. RO systems are capable of reducing the sodium content in water, making it a suitable option for individuals with hypertension or other medical concerns related to sodium intake.

Environmentally Friendly:

Compared to bottled water, which contributes to plastic waste and environmental pollution, RO water is a more sustainable and eco-friendly option. By installing an RO system in your home, you can reduce your reliance on single-use plastic bottles and minimize your environmental footprint.

Convenience and Accessibility:

With a reverse osmosis water purification system installed in your home, you’ll have access to clean and purified drinking water whenever you need it. There’s no need to purchase bottled water or rely on store-bought filters, saving you time, money, and effort in the long run.

Easy Maintenance:

RO systems are relatively low-maintenance compared to other water treatment methods. Routine maintenance typically involves replacing the pre-filters and post-filters periodically, as well as sanitizing the system to prevent bacterial growth. With proper care and maintenance, an RO system can provide years of reliable service.

Overall, RO water offers numerous benefits, including contaminant removal, improved taste, reduced sodium content, environmental friendliness, convenience, and easy maintenance. These advantages make it a popular choice for homeowners looking to ensure clean and safe drinking water for their families.

Cons of Reverse Osmosis Water:

While reverse osmosis (RO) water offers several benefits, it also has some potential drawbacks that homeowners should consider before investing in an RO water purification system. Here are some of the main cons of reverse osmosis water:

Wastewater Generation:

One of the primary drawbacks of reverse osmosis systems is the significant amount of wastewater generated during the purification process. For every gallon of purified water produced, RO systems can generate anywhere from 2 to 4 gallons of wastewater, depending on the system’s efficiency and design. This can lead to water waste and may not be environmentally sustainable in regions with water scarcity.

Removal of Essential Minerals:

RO water removes beneficial minerals such as calcium, magnesium, and potassium from water along with contaminants. While this can result in cleaner water, it may also lead to mineral deficiencies and potential health risks for individuals who rely on water as a source of essential nutrients. Some argue that drinking demineralized water long-term may have negative health effects.

Slow Filtration Rate:

RO systems have a relatively slow filtration rate compared to other water treatment methods. It can take several hours to produce a gallon of purified water, depending on the system’s size and capacity. This slow filtration rate may be inconvenient for households with high water consumption needs, as it may not be able to keep up with demand during peak usage times.

Initial Cost and Installation:

The upfront cost of purchasing and installing a reverse osmosis water purification system can be significant, especially for high-quality systems with advanced features. Additionally, installation may require professional assistance to ensure proper setup and operation, adding to the overall cost of the system.

Limited Contaminant Removal:

While RO is effective at removing many contaminants, it may not eliminate all impurities from water. Certain contaminants, such as volatile organic compounds (VOCs), pesticides, and pharmaceuticals, may require additional treatment methods for complete removal. This means that homeowners may need to invest in additional filtration systems or treatments to address specific water quality concerns.

pH Imbalance:

RO water tends to have a lower pH level, making it slightly acidic compared to untreated water. Drinking water with a low pH may affect the body’s acid-base balance and lead to health issues such as acid reflux or mineral leaching from teeth and bones. Some individuals may find the taste of slightly acidic water unappealing.

In conclusion, while reverse osmosis water offers several benefits such as contaminant removal and improved taste, it also has drawbacks such as wastewater generation, mineral removal, slow filtration rate, initial cost and installation, limited contaminant removal, and pH imbalance. Homeowners should carefully weigh these pros and cons and consider their specific water treatment needs before deciding whether reverse osmosis water is the right choice for their household.
