What are RO Water Purifiers, their types, and their advantages?

With the recent growth in urbanization and industrial development, there is also a growth of contamination in the natural water supply. Such water if used for drinking purposes for a prolonged period of time will cause illnesses. Due to this, installing a Water Purifier at home has become essential. Before deciding to install a Water Purifier, there are a few basics to keep in mind.

What is RO Water Purifier?

RO Water Purifier as the name suggests is a Reverse Osmosis Water Purifier. It works through the process of Reverse Osmosis. It uses a semi-permeable membrane to purify water and lower the TDS of water. The raw hard water passes through the RO Membrane with the help of a pump. During this dissolved solids like fluoride, lead, sulfates, etc are trapped, stuck in the RO membrane, and get purified water as a result.

What is TDS?

TDS or Total Dissolved Solid refers to the number of contaminants present in water. The contaminants may be calcium, chlorides, or bicarbonates. If the tap water has high TDS content, then there is a need for a RO Water Purifier to make it fit for drinking. TDS level is also dependent on the source of water.

Why is the maintenance of a Water Purifier needed?

A Water Purifier needs regular maintenance for its optimal and efficient functioning. Replacement of the filters in a timely manner is also essential to ensure that Water Purifier runs efficiently. The filters are needed to be changed periodically, as the contaminants from water begin to clog their filters. If filters are not changed regularly then it can affect the quality of water, as the impurities are transferred to the drinking water.

Different Filters used in Water Purifiers

Sediment Filter – It is one of the multiple filters used to remove impurities in a RO Water Purifier. A sediment filter acts as a strainer in removing impurities from the water which is recommended to change once every year. Maintaining this filter helps protects the RO membranes from dirt and reduces sediment.

Carbon Filter - Water from the sediment filter is passed through the carbon filter, which removes chlorine and other contaminants. It filters out any kind of odor and unpleasant taste from the water. It is recommended to change the carbon filter once a year so that it doesn’t affect the performance of the RO membrane.

RO Membrane – Being the most important part of any RO water purifier the RO Membrane is effective in reducing total dissolved solids (TDS) from the water. The RO Membrane, for optimal performance, needs to be replaced once a year or once in two years, depending on the consumption of water at home.

Types of Water Purifiers offered by Pearl Water

  • Gravity Water Purifiers

Gravity Water Purifiers are those purifiers that work by using the force of gravity. These Water Purifiers work without any need for electricity for their function. It consists of a Ceramic filter and Filter cartridge.

The Ceramic filter's function is to filter all dirt, sand particles, and bacteria to ensure that the water free from any harmful diseases causing bacteria.

The Filter cartridge comes with a multi-stage cartridge that removes impurities such as bacteria, contaminants, etc, and retains all the good minerals and nutrients in the water.

  • RO Water Purifier

A RO Water Purifier helps in removing contaminants, suspended solids, chemicals, and odors from contaminated drinking water through the process of Reverse Osmosis. There are 3 types of RO Water purifiers offered by Pearl Water –

  • Classic Water Purifier
  • Ultra Water Purifier
  • Ultra Plus Purifier

Each three Water Purifier consists of different filters like RO Membrane, Sediment filter, Carbon Filter, Alkaline filter, and UV for purification.

High TDS RO Membrane helps in trapping the smaller, harder-to-remove dissolved solid particles through the process of Reverse Osmosis.

A Sediment filter captures and removes sand, silt, dirt, and rust from water. Removing particulates from water protects a RO Membrane.

Carbon filters remove chemicals and organic compounds like chlorine, and pesticides. The smell and odor from water are also removed while the taste of water is improved.

An Alkaline filter works to filter out harmful contaminants like micro-plastics, heavy metals, bacteria, and chemicals while retaining essential life-sustaining natural electrolytes.

Ultraviolet (UV) is used for removing microorganisms or bacteria or viruses from the water. Ultraviolet rays destroy the growth of illness-causing microorganisms and harmful pathogens in water.

Advantages of RO Water Purifier

  • Availability of pure and safe drinking water

Having a Water Purifier in the home will ensure safe and pure drinking water at any time required.

  • Elimination of different disease-causing microorganisms

RO and UV technologies used in Water Purifiers eliminate the disease-causing microorganisms present in water.

  • Removal of Dissolved Solids

Water Purifiers help in removing dissolved solids, thereby making the safe for consumption.

  • High Storage Capacity

Water purifiers have high storage capacity meaning that a substantial quantity of water is stored in the purifier which ensures that water is available whenever required.

  • Cost-effective

Having a Water Purifier is more economical than buying bottled water because the latter is neither cost-effective nor environment-friendly as it generates huge plastic waste.

How to Select the Best Water Purifier for Home?

There are various techniques involved in water purification in a Water Purifier. A few types of water purifiers are RO, UV, and UF. There are combinations of these techniques used in water purifiers. The TDS level of tap water has to be checked to decide which purification technique would suit the need best. Other things to consider before buying a Water Purifier -

  • Storage capacity as per family size
  • Material of storage tank
  • Preference for hot water options
  • Maintenance cost


Water Purifiers are very much required for the need for clean water. Not only do they remove impurities from raw but also are cost-effective. With different purification techniques such as UF, UV, etc the benefits of having RO Water Purifiers is endless.
