This type of reverse osmosis water purifier is designed to remove harmful contaminants from water easily. Which, in turn, gives your family pure and fresh-tasting water every day.

In this guide, we’ll break down what an RO water purifier is, how it works, and the benefits. Added to that, you’ll also find the price range of RO filters in Bangladesh for 2025. So, without further ado, let’s dive into it.

What is RO Water Purifier?

An RO (Reverse Osmosis) water purifier is a filtration system that uses a semi-permeable membrane to remove dissolved salts, heavy metals, chemicals, and other impurities from water.

The basic water filters usually only trap dirt and larger particles. But RO purifiers are different compared to normal ones as they go a step further by targeting contaminants at the molecular level.

As a result, RO purifiers have become one of the most reliable options for households, offices, and even restaurants in Bangladesh, where water quality often varies.

How Does an RO Water Purifier Work?

An RO water purifier pushes tap water through a very fine, semi-permeable membrane using pressure. That membrane traps things you do not want in your drinking water, like dissolved salts, arsenic, some heavy metals, and bacteria. 

Since the RO membrane has extremely fine pores, an RO filter booster pump is required to force water through the filters. 

It is used to ensure the system works efficiently and delivers a steady flow of purified water. The tiny gaps in the membrane let mostly water molecules through, so the output is much cleaner than the input.

Most RO systems also come with additional filters, such as activated carbon filters, sediment filters, and post-carbon filters. These filters remove bad odor, dirt, and chlorine and improve the overall taste of water.

RO Filtration Process

RO filtration takes place in a few steps. First of all, the water goes through a sediment filter that catches things you can see, like sand or rust. Then it advances through an activated carbon filter. This helps remove the chlorine from the tap water and improves the taste and smell.

The real magic happens in the reverse osmosis membrane. It has so tiny pores (ranging from 0.0001 to 0.001 microns) that only water molecules can get through those. But the impurities are trapped.

After filtering, the clean water goes into a storage tank, while the leftover contaminants are washed away as wastewater through a separate waste line.

Some advanced RO purifiers add a final carbon or mineral filter. It makes the water taste better and replaces important minerals that might have been removed during filtration.

Difference Between RO and Normal Filter

A normal water filter works by removing the visible dirt, sand, or suspended particles. As a result, you will see the filtered water look cleaner. But it does not remove dissolved impurities like arsenic, lead, or excess salts.

On the flip side, an RO water purifier targets both visible and invisible contaminants. It filters out all the invisible impurities like arsenic, harmful bacteria, dangerous chemicals, and heavy metals that a regular filter cannot handle.

In short, a normal filter improves appearance and taste, while an RO purifier delivers safe, pure drinking water suitable for long-term health.

Benefits of RO Water Purifier

An RO water purifier offers several advantages that go beyond just clean water. Some of the key benefits include:

• Removes harmful contaminants: RO filters can easily remove invisible impurities like harsh chemicals, pesticides, salts, etc., that can cause health problems.
• Improves taste and odor: In Bangladesh, you’ll find chlorine even in tap water. RO filters can remove such chemicals as sulfur, chlorine, and so on to improve the taste and color of water.
• Safe for cooking and drinking: It also makes water suitable for cooking and cleaning hygienically
• Protects health: It helps reduce the risk of waterborne diseases common in Bangladesh.
• Convenient and reliable: No need to buy bottled water when you’ve an RO water purifier

These benefits make RO water purifiers one of the most trusted choices for households and businesses alike.

Why You Need RO Water Purifier?

In many parts of our country, water sources are contaminated with iron, arsenic, bacteria, or high levels of dissolved salts. You cannot see these impurities with your eyes. 

But they can seriously affect your health over time. You might know that boiling water can kill germs. Yes, it can. But it cannot remove dissolved chemicals or heavy metals.

This is where an RO water purifier becomes vital. It can easily purify your water from invisible impurities. Whether you live in a city with municipal water or in a rural area with tube well water, an RO purifier provides consistent protection.
