Pros of RO Water Filters

  1. Exceptional Filtration: One of the most significant advantages of RO water filters is their multi-stage filtration capability. These filters can effectively remove impurities like bacteria, viruses, heavy metals, chlorine, and even dissolved salts from the water. This ensures that you get clean and safe drinking water.
  2. Improved Taste and Odor: By eliminating contaminants that affect taste and odor, RO water filters can greatly improve the overall quality of the water you drink. The result is water that not only looks clean but also tastes and smells refreshing.
  3. Reduces Harmful Minerals: RO filters are effective at removing harmful minerals like lead and mercury from the water. This can be especially crucial in areas where the water supply contains high levels of these substances.
  4. Better for Cooking: Purified water from an RO filter can enhance the flavors of your cooked dishes, as it doesn’t contain impurities that can affect the taste of your food.
  5. Easy Installation: RO water filters are relatively easy to install, and many models come with installation instructions that make the process hassle-free.


Cons of RO Water Filters

  1. Water Wastage: One of the primary drawbacks of RO water filters is that they produce wastewater as a by-product of the filtration process. This can lead to water wastage, which is a concern in regions facing water scarcity.
  2. Filter Replacement: RO filters require periodic filter replacements to maintain their effectiveness. These filter replacements can add to the maintenance costs over time.
  3. Slow Filtration: The process of reverse osmosis can be slower compared to other types of water filtration. This means that filling up large containers or using purified water for immediate consumption might take a bit longer.
  4. Removes Beneficial Minerals: While RO filters are excellent at removing harmful contaminants, they also remove some beneficial minerals naturally found in water. This can lead to water that is slightly demineralized.
  5. Initial Cost: The initial cost of purchasing and installing an RO water filter can be relatively higher compared to some other types of water purification systems. However, this cost may be justified by the quality of the purification provided.


In conclusion, RO water filters have undeniable advantages when it comes to providing clean and safe drinking water. They excel at removing a wide range of contaminants and enhancing water quality. However, they also come with drawbacks, such as water wastage and the removal of beneficial minerals.

When considering an RO water filter, it’s crucial to evaluate both the initial cost and the ongoing maintenance expenses. Look into options like AMC contracts to ensure that your purifier is well-maintained and functions effectively over time.

In the end, it’s important to choose a water purifier that matches your area’s water condition. Eureka Forbes offers tailored recommendations based on your water supply source. Simply put your pin code, and it will suggest the most suitable option from its wide range of water purifiers.
