Clean drinking water is essential to good health and well-being. Investing in a water purifier is an effective way to ensure clean drinking water. Selecting the appropriate water purifier can be difficult with so many available in the market.

In this article, we will discuss how to select a Water Purifier that meets your needs. Let’s dive deeper into the essential factors you should consider when searching for the ideal purifier for your home!

How to select a water purifier?

Assess Your Water Supply

Prior to selecting a water purifier, it is vitally important that you fully understand the water quality. Testing the TDS and hardness levels will allow you to select an appropriate purifier to address your specific needs.

Select the appropriate purification technology: Based on the results of your water test, select a purifier with appropriate purification technology such as:

RO (Reverse Osmosis): Reverse Osmosis is an ideal method to remove impurities in water with high TDS levels, hardness and heavy metal contamination. This process works by forcing it through a semi-permeable membrane to filter out impurities effectively.

UV (Ultraviolet) light technology: Ideal for eliminating bacteria, viruses and other microorganisms without changing its taste or aroma.
c. Ultrafiltration (UF): Ultrafiltration can remove suspended particles, bacteria and cysts from water; however, it may not be appropriate for reducing TDS levels or heavy metal contamination.

Consider Storage Capacity:

Select a water purifier with sufficient storage capacity based on your household’s water consumption and electricity availability. A larger capacity ensures access to clean drinking water even during power outages.

Maintenance and after-sales service:

Regular maintenance must occur for optimal operation of a water purifier. Choose one with readily available replacement filters and reliable after-sales support services.


Water purifiers come with various price points. Establish your budget and choose one that provides maximum value without compromising essential features.

How to Select an RO Water Purifier?

Consider these factors when purchasing an RO water purifier:

Type of RO Membrane:

Choose an RO purifier featuring high-grade membranes such as thin-film composite (TFC) or cellulose triacetate (CTA) for optimal purification and durability. These will offer effective purification.

Pre-filters and post-filters: 

An RO purifier must contain pre-filters to protect its RO membrane from sediment or chlorine damage and post-filters such as carbon filters to enhance water taste and taste.

TDS controller/mineralizer:

RO purification can strip essential minerals out of water, so consider purchasing a purifier equipped with either a TDS controller or mineralizer to maintain sufficient mineral levels in purified water.


Choosing an effective water purifier involves assessing your water quality, choosing an effective purification technology, and considering factors like storage capacity, maintenance costs and budget constraints. By adhering to these guidelines on selecting an RO water purifier, you can ensure your family can access safe and healthy beverages for drinking.
