RO Water Purifier and Water Purification Systems

Water is a basic necessity of life. We need it for drinking, cooking, and cleaning. But what happens when the water we use is contaminated? This is where water purifiers and water purification systems come into play. In this guide, we will discuss everything you need to know about RO water purifiers and water purification systems.

What is a RO Water Purifier?

A RO (Reverse Osmosis) water purifier is a type of water filter that uses a semipermeable membrane to remove impurities from water. It is one of the most popular water purification methods because it is effective in removing contaminants such as lead, arsenic, fluoride, and chlorine.

How Does a RO Water Purifier Work?

A RO water purifier works by passing water through a semipermeable membrane that traps impurities and allows only pure water to pass through. The process involves three stages:

  1. Pre-filtration: The water is passed through a sediment filter that removes larger particles like sand and mud.
  2. RO filtration: The water is then passed through the semipermeable membrane that removes impurities like bacteria, viruses, and heavy metals.
  3. Post-filtration: The water is passed through an activated carbon filter that removes any remaining impurities and improves the taste of the water.

Types of RO Water Purifiers

There are different types of RO water purifiers available in the market, and they vary in terms of design, features, and technology.

Wall Mounted RO Water Purifiers

Wall-mounted RO water purifiers are designed to be mounted on a wall and are ideal for small spaces. They are compact and take up very little space, making them perfect for apartments and small households.

Under Sink RO Water Purifiers

Under sink RO water purifiers are installed under the sink and are connected to the main water supply. They are ideal for larger households and commercial establishments.

Portable RO Water Purifiers

Portable RO water purifiers are designed for people who are always on the move. They are compact and lightweight, making them easy to carry around. They are perfect for outdoor activities like camping, hiking, and backpacking.

Advantages of Using a RO Water Purifier

Using a RO water purifier has several advantages, including:

  • Removes impurities and contaminants from water
  • Improves the taste and odor of water
  • Reduces the risk of waterborne diseases
  • Cost-effective and environmentally friendly
  • Easy to install and maintain

Factors to Consider When Choosing a RO Water Purifier

When choosing a RO water purifier, there are several factors you should consider, including:

Water Quality

The quality of the water in your area is an important factor to consider. If the water is heavily contaminated, you will need a purifier that is capable of removing all impurities.


RO water purifiers come in different price ranges, and you should choose one that fits your budget. Keep in mind that more expensive purifiers often come with more advanced features and better filtration technology.

Size and Capacity

The size and capacity of the purifier should be based on the number of people in your household and the amount of water you consume on a daily basis.

Brand and Reputation

Choose a purifier from a reputable brand that has a good track record in the market. You can read reviews and ask for recommendations from friends and family.

Maintaining Your RO Water Purifier

To ensure that your RO water purifier continues to function effectively, you need to maintain it regularly. Here are some tips:

  • Replace the filters as recommended by the manufacturer
  • Clean the purifier regularly
  • Check the purifier for leaks

Common Problems with RO Water Purifiers

Despite their effectiveness, RO water purifiers can face some common problems, such as:

  • Clogging of the membrane due to high TDS (Total Dissolved Solids)
  • Membrane damage due to high pressure
  • Leakage from the purifier
  • Foul smell or taste of water

If you face any of these problems, it is best to call a professional technician to diagnose and fix the issue.

Water Purification Systems

Apart from RO water purifiers, there are other types of water purification systems available in the market. Let’s take a look at some of them:

UV Water Purifiers

UV (Ultraviolet) water purifiers use ultraviolet rays to kill bacteria and viruses present in water. They are effective in removing impurities but do not remove dissolved solids.

Gravity-Based Water Purifiers

Gravity-based water purifiers do not require electricity and use the force of gravity to filter water. They are effective in removing impurities but do not remove dissolved solids.

Carbon Block Water Filters

Carbon block water filters use activated carbon to remove impurities from water. They are effective in removing chlorine, sediment, and volatile organic compounds (VOCs).


A RO water purifier is an essential appliance for ensuring the safety and purity of drinking water. When choosing a purifier, it is important to consider factors like water quality, budget, and size. Regular maintenance is also crucial to ensure the longevity and effectiveness of the purifier. Other types of water purification systems like UV purifiers, gravity-based purifiers, and carbon block filters are also available in the market.


  1. What is the difference between a RO water purifier and a UV water purifier?
  • A RO water purifier uses a semipermeable membrane to remove impurities, while a UV water purifier uses ultraviolet rays to kill bacteria and viruses.
  1. How often should I replace the filters in my RO water purifier?
  • It is recommended to replace the filters every 6 to 12 months, depending on the usage and water quality.
  1. Can a RO water purifier remove salt from water?
  • Yes, a RO water purifier can remove salt from water.
  1. Is it safe to drink water from a RO water purifier?
  • Yes, water from a RO water purifier is safe to drink as it is free from impurities and contaminants.
  1. Do RO water purifiers waste water?
  • Yes, RO water purifiers waste some water during the filtration process, but modern purifiers are designed to be more efficient and use less water.
