Best Water Purifier

It is no secret that water is the elixir of life and that its quality directly impacts our health. While most of us are fortunate enough to have clean drinking water, there are still many parts of the world where this is not the case. In India, for instance, a large percentage of the population does not have access to clean drinking water. As a result, water-borne diseases are a major problem in our country.

Many regions have hard water, which contains high levels of minerals such as calcium and magnesium. These minerals can cause problems such as dry skin, hair loss, and scale buildup in pipes.

One of the best ways to safeguard your family’s health is to invest in a good water purifier. A water purifier will not only remove all the impurities from your water but also make it safe for you to drink.

Now that so many options are available in the market, it can be difficult to pick the right one. For instance, in regions where the TDS levels are above 400ppm, only an RO water purifier can remove metal particles to make it safe for drinking, while in other cases, a UV water purifier with a TDS controller will suffice.

This buying guide will help you pick the best water purifier for your home. We have also reviewed the 9 best water purifiers available in the market.

What to Look for When Buying a Water Purifier? - Water Purifier Buying Guide

Before buying a water purifier, you should know a few things to help you make an informed buying decision:

TDS level of your tap water

The very first thing you should do before buying a water purifier is to get your water checked for impurities, hardness, and TDS. Total dissolved solids (TDS) is a parameter that shows the level of pollutants in water. Pick a water purifier that can handle the TDS levels in your region.

Keep in mind that not every water purifier can manage high TDS levels.

Purification Technology

There are several different types of water purification technologies available in the market. The most common ones are RO, UV, and UF. Depending on the type of water supply in your region, select a water purifier with the technology to provide you with the safest drinking water.

Certain models come with purification technology using 7 or 8 steps.

Filtration Capacity

You should determine the average amount of water your household consumes daily to buy an appropriately sized water purifier. If you have a big family, getting a water purifier that can store at least 8 liters of water would be ideal.

Durability & Materials

Water purifiers usually come with storage tanks made of food-grade plastic or stainless steel. Purified water might catch bacteria or germs in a plastic water purifier. Stainless-steel storage tanks provide more extended periods of protection against the growth of bacteria and germs than plastic storage tanks.


Check the number of filters a water purifier has. More filters mean more chances of impurities being removed from the water. Check if the filters are easy to replace or not & always choose high-quality and reliable filters.

Warranty and Price

Opt for a purifier that is not only affordable but also has an extensive warranty period to safeguard your investment. A long-term warranty should be one of your primary criteria when choosing a model. Many brands offer at least 1 year of coverage.

Cleaning & Maintenance

When shopping for a water purifier, pick one that is easy to install and manage. Cleaning your device regularly will allow it to perform at its best. While some companies might offer free maintenance services, others may charge an additional fee.

TDS Controller

TDS, or Total Dissolved Solids, is an important monitor in any water purifier. TDS controller ensures that the level of dissolved solids is where it should be. Not every region needs a TDS controller and not every water purifier is equipped with an adjustable TDS controller.

Water-Saving features

The water purifier must have a water-saving feature because RO purifiers can waste a lot of water. If you live in a region where water scarcity is a problem then make sure you do not select the water purifiers that have a recovery rate of less than 50%.

How Do the Reverse Osmosis Water Purifiers Work?

RO water purifier uses a semi-permeable membrane to filter water. The water is pumped through the RO membrane by a water pump, pressuring the hard water to pass through. The dissolved metals and solids like arsenic, fluoride, lead, chlorine, nitrates, and sulfates are captured and stuck to the RO membrane, filtering out the water and leaving the impurities behind.

The Water Purification Process and Key Terms Explained

Sediment Filter

Sediment filters are the first stage of filtration in most water purifiers. They help remove suspended particles from the water, including sand, dirt & other solid particles.

Activated Carbon Pre-Filter

An activated carbon pre-filter helps to remove chlorine, chemicals, and other contaminants from the water.

RO Membrane

Reverse Osmosis is like a filter that drives all water particles through a tiny semi-permeable membrane. All particles too large to follow the water’s path are filtered out by forcing water through this semi-permeable membrane.

UV Purification

Ultraviolet or UV is an additional light that disinfects the water by eliminating bacteria and viruses when the water is stored in the stage tanks.

UF Membrane

Water is passed through an Ultra Filteration or UF membrane to remove impurities. The UF membrane has tiny pores that allow only water molecules to pass through.

TDS Controller

A TDS controller helps to regulate the level of dissolved solids in water. This is important because too much or too little dissolved solids can harm your health.


When water is purified, the minerals are also removed along with the impurities which influence the flavor of the water. To restore the taste, purifier companies add a mineralizer cartridge to balance the taste & add essential minerals.

Carbon Post Filter

After purifying the water with the RO and UV purification stages, a layer of carbon filter, known as the Post-RO Carbon filter, is added. This filter is commonly used at the end of the water purification process. It aids in improving the water’s quality and functions as a polisher, making pure water taste even better.


Silver Charged Membrane Technology is a secondary purification stage that effectively eliminates most pollutants and germs after RO purification. This technology outperforms UF, MF, and UV.

Storage Tank

Storage tanks are containers that hold purified water filtered by a filtration system so you can utilize it according to your needs.

Frequently Asked Questions (FAQs) - Water Purifiers

Water filter or water purifier?

Water purifiers are often confused with water filters, but they are two distinct devices. A water filter separates particles and impurities from water, making it clean and safe to consume and use for other purposes such as washing, cleaning, and cooking. Water purifiers take it one step further by removing biological pollutants (viruses and germs), hazardous chemicals, metals, solid particles, and toxic gases from the polluted water. Reverse osmosis (RO), distillation, and UV treatment are all used by water purifiers to remove contaminants.

How To Know Which Type of Water Purifier You Need?

To find out what kind of water purifier you need, you should get your tap water checked for impurities. You should also find out the daily consumption of water and storage capacity in your house. Safety and maintenance should also be taken into consideration. After this, you can easily find a suitable water purifier to satisfy your requirements.

How Can I Check My Home Water TDS?

You can quickly check the TDS of your water at home with a digital TDS meter or a filter paper and a scaling machine. Simply take a sample of your water with the help of a pipette and let it filter through the filter paper. Weigh the particles left behind on the filter paper with the scaling machine to find out the TDS of your water.

What Is a Good PPM For Water?

Water with a low TDS level of 50 to 150 is suitable for your health. A low TDS level indicates that the water is of excellent quality, although it may be tasteless due to the lack of minerals. 

What Is The PPM Of Pure Water?

The ppm of pure water should be around zero or less. Average tap water has a ppm of 180–320

Is RO Water Better Or UV For Health?

RO purifiers are the finest appliances for water purification. RO water is better for your health as it eliminates all impurifications. But there is a catch. It strips the essential minerals and salts out of the water, which could be harmful in the long term. RO is also more effective than UV purifiers as they contain multiple filtration stages. On the other hand, UV purifiers are the most cost-effective option for individuals on a tight budget. They have the advantage of destroying all dangerous bacteria found in water, even though they do not eliminate them.


A water purifier is an essential appliance for every household. It removes impurities and contaminants from water, making it safe to drink and use. Different types of water purifiers are available in the market, and each has its own advantages and disadvantages. Choose the one that best suits your needs and budget.
