Buying Guide – Must Consider Before Buying a Best Water Purifier

In this section, you will get ideas about the factors that require consideration before buying a water purifier. The FAQs will also give you extensive knowledge. 

How to Choose the Right Water Purifier?

Go through these factors:

Water Quality

Understanding of the quality of the water purifier is essential before buying a water purifier. The impurities found in water supply include harmful pollutants, bacteria, viruses, Chemicals, and hardness. Before buying a purifier, you should have knowledge about these contaminants and the source of water. Make a choice of the water purifier based on the drinking water source. 

Usually, the sources are lakes, rivers, borewells, harvested rainwater, and Municipal Corporation. Supplying water based on the level of dissolved salt is soft or hard. 

Levels of Contamination in Your Area

Water in the houses is supplied organically without a filtration process through pipes. They are prone to contaminants like bacteria, nitrate, dissolved pesticides, and lead. We will suggest opting for UV based or RO filtration based water purifiers for removing the contaminants. The UV effect will irradiate the infiltrates in water. With time, the microorganisms diminish and die. The presence of the RO membrane will make water good for consumption.

Water Purifier-type

After understanding the quality of water supplied, you can choose RO, UV, or UF type of water purifier purification. RO will help in times of high TDS water supply. In the case of low TDS, it is better to go ahead with UV and UF purifiers. They are capable of killing the virus or bacteria present in water.

Storage Capacity

Before buying the water purifier, you should consider the capacity of storage. It is necessary especially for those areas that are prone to power cut issues. In case you want a continuous supply of the purified water, it is better to go with the model that has more capacity. There is another alternative to it. Activated carbon purifiers are also incredible in terms of their storage capacity. 

Water Pressure

RO and UV filters need water supply available at a specific pressure. When the incoming water flow develops a less efficient force, the RO filter will not work properly. So, you must check the water supply pressure at your home before buying the water purifier. In case it is insufficient, you should buy the activated carbon purifier. But when the water is high in its TDS and contamination, it is better to go ahead with the RO purifier. The attached pump RO filtration will boost the pressure. 

Daily Usage

Analysis of the average daily consumption of water for your family is essential before buying a water purifier. If the daily consumption is high, it’s better to opt for the high power and high output rate-based model. In case, iI is slow, you can purchase the small versions of the water purifier. The decision of the number of users is also essential before buying it. If you are living in a joint family, a water purifier with less quantity of water becomes useless. The output of water from the water purifier should never be less than the total members of the family.


The RO and UV water purifier run on electricity. So, if you are staying in an area that has frequent power cut instances of insufficient electricity supply, it is better to opt for the alternate water purifier. It will cope up with the power cuts.

Purification Technology and Process

The selection of the best water purifier is largely based on purification Technology. The technology for water purification also affects the quality of water. Water purifiers will come with a mechanism to filter the contaminated water. TDS control stands will guide the purification technique for control of the final TDS. It will also give benefits in terms of enhancing the taste of water. You should also see that the water purifier has pH balance Technology for balancing the pH levels in the water. Check the number of purification stages before buying a water purifier.

Why Does TDS Become Such An Essential Consideration While Buying a Water Purifier?

TDS refers to total dissolved solids that represent the concentration of dissolved substances. It includes inorganic salts like magnesium, potassium, calcium, and sodium. Besides, it also includes chlorides and sulfates. BIS suggests that the ideal TDS is below 300mg/L. Again, the max permissible limit is 600mg/L. Patients with kidney problems must consume water with a TDS level below 100 mg/L. TDS measurement becomes essential because high levels of TDS impacts the taste of drinking water. Again, high TDS water is often safe. But, ingredients like lead or copper become hazardous for health. 

It’s true that low TDS means high-quality water. At the same time, low TDS causes water to develop the flat taste. It’s good to remember that the levels from 300-500 become the right TDS levels for drinking water. When you purchase the Reverse osmosis based water purifier, you can see that it will reduce TDS to about 10% of the current water level. It’s good to remember that Active carbon filters do not have the capability of removing TDS.

As we know that, High levels of TDS degrade the taste of drinking water, you must conduct routine testing for assurance that the filter works properly. 

Though there is no known scientific data for clearly demonstrating that the low TDS water consumption will cause harm, yet it’s good to stick to the generalized amount. There’s a common misbelief that boiling water removes the dissolved solids. But that’s not true. In fact, the level of TDS increases when boiling. It’s always good to opt for a high-end water purifier rather than simply consuming boiled water. 

So, before buying a water purifier, you must consider the TDS levels. 


Each of the above-mentioned water purifiers is packed with rich features that will ensure safe drinking water. Choose the system that will be suitable for the health of your family. The customer reviews suggest that the above-mentioned purifiers hold the essential specifications to stand out. Finally, we are at the end of the long and detailed review. By now, you have got ideas about the best water purifiers.
