Water Purifiers Buyers Guide & Faq

Now that you are well aware of some of the best water purifiers let us dig a little deeper and know the reasons that make water purifiers a necessity.

Why water is important to human health

Water is one of the basic needs of life. Our body requires an adequate amount of water to perform different functions. Water also regulates the body temperature that helps us sustain in extreme climatic conditions. The importance of water to human health is well-familiar.

Our body loses a significant amount of water when we indulge in physical activities. If not, the processes like breathing, sweating, and digestion also decrease a considerable amount. Therefore, it is imperative to replenish this loss of fluid and keep the body hydrated all the time by drinking water.

Best water purifiers in india

At the same time, drinking pure and freshwater is also very important to sustain good health. Today when water pollution is at its peak, and every source of water is getting contaminated, you can’t rely on the tap water. Drinking pure water is as essential as breathing pure air to prevent harmful and deadly water-borne diseases. Therefore, water purification has become utmost important.

Importance of water purification

• Removes the contamination
• Reduces the chances of water-borne diseases
• Adds back the essential minerals to the water
• Lowers down the chlorine level
• Lowers bacteria levels
• Improves the water quality
• Makes the water healthier and tastier

 

Since there are ample reasons for consuming purified water, different companies have manufactured water purifiers based on different purification techniques.

Types of water purifiers

1. Reverse Osmosis water purifiers

RO water purifiers have a semi-permeable membrane through which the raw water passes. The water pump exerts pressure that removes the dissolved impurities like lead, chlorine, arsenic, nitrates, fluoride, and sulfates. Every metal particle, as well as suspended solids and chemicals, are believed to eliminate with an RO water purifier.

AdvantagesDis Advantages
Eradicates dissolved impurities including salts and metal particlesRun with electricity
Removes water-borne disease causing microorganisms and germsRequires running water
Improves the taste and odor of waterWastes water during purification
They are easy to maintain and cost-effective

2. UV water purifier

Such purifiers utilize ultraviolet light to accomplish water purification. The water passes through the UV lamp that emits UV radiations. As soon as the water is exposed to the UV light, all the germs and microorganisms get killed. UV water purifiers are considered best for water with low TDS like river and lakes. It is not able to treat water with a high level of TDS.

AdvantagesDis Advantages
Purification rate is highDead microorganisms remain in water although they are not harmful
Can purify more water in lesser timeDoes not remove the dissolved metals, contaminants and toxic chemicals
Low maintenance costNot capable enough for water with high TDS
Consumes less electricityNot effective against turbid or mud water
Keep the essential minerals in the water

3. UF water purifier

Ultra filtration (UF) water purifiers utilize hollow fibers of a membrane, made up of a thin layer of materials that can easily separate the water and contaminants. All the solid impurities along with harmful microbes and germs get trapped inside the UF membrane, cleansing the water thoroughly. It is suitable for water with low TDS, low chemical contamination, and low dissolved salts.

AdvantagesDis Advantages
Doesn’t require electricityNot effective against hard water and water with high TDS
Blocks the bacteria and virusesRequires regular cleaning at least twice in a week
Does not uses chemicals for purification
Filter out dirty and muddy water
Cost-efficient
User-friendly interface
Long lifespan

4. Activated carbon water purifier

Made up of coal, coconut shell, wood, nutshells, and preferably charcoal, an activated carbon eliminates heavy metals and pesticides that may cause water-borne diseases. It also removes harmful chemicals like chlorine from water, making it tastier and odor-free. Activated carbon absorbs the impurities present in the water and passes the purified water in the storage tank.

AdvantagesDis Advantages
Removes pesticides and heavy metalsDoesn’t remove dissolved salts
Removes odorDoesn’t remove microbes and germs
Make water tastier and healthierRequire regular maintenance for better purification
When used with RO water purifiers, it enhances the life of the RO membrane.

5. Sediment filter

Sediment filter is used along with RO and UV water purifiers to remove the sediments that collect at the bottom of the water. Sand particles, mud, metal flakes, rust flakes are some of the unwanted materials that filter out with the help of sediment filter. Generally, sediment filter are made from polyester fibers or cotton.

AdvantagesDis Advantages
Removes the sediment completelyNot able to remove heavy metals, dissolved salt, and microorganisms
Eliminates every visible contaminantRequire regular maintenance
Increases the life of RO and UV by pre-filtering the sediments

 Different sources of water

Water reaches our home from different sources. Generally, municipal water is the major source of supply in most of the urban cities. However, many households rely on groundwater for their water requirements. Let’s find out the major water sources, their characteristics, and ideal water purifiers for them.

Best water purifiers in india

Surface Water

Water that collects on the surface of the ground comes under surface water. Rivers, lakes, and wetlands are some common examples of surface water that are supplied to the households through municipal. It is also called municipal water.

Generally, surface water is a result of rainwater harvest. The amount of contaminants and impurities are often low. This water is not hard, and the value of the TDS range between 1- 200 ppm. Moreover, the municipal corporation purifies the water before supplying it to the households.

So the question is, do we really need a water purifier for surface water? If yes, then which water purifier- RO, UV or UF?
Why we need a water purifier for surface water?

The need for water purifier for surface water is due to the following reasons:
• Factories and industries dump their thrash, including harmful chemicals and heavy metals into the river, making it contaminated.
• Municipal corporations treat water to remove bacteria and virus and not chemicals and heavy metals.
• Water is purified with the help of chlorine which is not suitable for health and needs further purification.
• Water travel to your tap through pipelines wherein the chances of leakage and contamination are always high.

 

Which water purifier is best for surface water?

Since the surface water is treated with chlorine, which is harmful to health, activated carbon purification technology can help getting rid of it. RO water purifiers and gravity-based water purifiers are the best choices where the supply is coming from surface water. Almost every RO and gravity-based water purifiers are equipped with activated carbon as one of the purification processes.

Ground Water

Another major source of water supply is from groundwater which is also called borewell water. Since natural sources of water like rivers and lakes are continually depleting, the dependency of bore well is increasing. Although groundwater is suitable for drinking, the level of hardness is considerably high. The TDS ranges between 200-2000 ppm, making it unsafe to drink without purification.

Best water purifiers in india

Which water purifier is best for groundwater?

The level of calcium and magnesium in groundwater are high, making it hard. Although hard water is not health hazardous, it contributes to making the water taste sour. Therefore, you can simply go for an RO water purifier which with its reverse osmosis process check out the traces of heavy metals, if any and improves the taste, odor, color and overall quality of the water.

Note: If you are unsure of the water quality, always go for a water test and confirm the presence of heavy metals and other harmful contaminants. Accordingly, you can decide which water purifier will be the best for you- RO, UV, UF, or simply the gravity-based.

TDS

Best water purifiers in india

Total Dissolved Solids or TDS signifies the total concentration of dissolved substances in water that include organic and inorganic salts. Some of the salts that are majorly found dissolved in water include potassium, magnesium, calcium, sodium, sulfates, bicarbonates, and chlorides and small amounts of organic matter. TDS is expressed in parts per million (ppm) or mg per unit volume of water (mg/L).

TDS Acceptability Level

Total dissolved solids alone are not considered harmful to health. However, when combined with other factors, they could pose health, cosmetic, and aesthetic issues. As per the World Health Organization (WHO), the following acceptability level has been documented:

TDS level in mg/lAcceptability level
Less than 300Excellent quality and perfect to drink
300-500Good
600-900Fairly acceptable
900-1200Poor
Above 1200Unacceptable range

Consuming water within acceptable TDS range reduces the chances of some of the major health issues. At the same time, drinking water with very less TDS is also not good. For example, if the TDS of water is below 100 ppm, it may result in cardiovascular diseases and hair fall. Also, water with low TDS can dissolve the plastic in which it is kept, increasing the chances of cancer and reduced immunity. On the other hand, water between 50-100 ppm is safe for people with kidney problems due to less dissolved solids.

Bureau of Indian Standards (BIS) has set the upper limit of TDS level in drinking water to be 500 ppm. Different countries and organizations have set their own standards. However, the one issued by WHO is considered the most reliable and trustworthy.

Different TDS level and their effects on human health

TDS level in mg/lEffects 
Less than 50 ppmUnacceptable due to less dissolved salts and the essential minerals that are must for human health
50-150 ppmAcceptable level as it contains essential minerals
150-250 ppmIt is perfect especially for people dealing with heart issues
250-350 ppmIt is an acceptable range and found in most of the Indian homes
350-500Fairly acceptable
500-900This is an unacceptable range and requires water purifier to reduce the level back to 500 ppm
900-1200 ppmUnacceptable and require water purifier with TDS controller to reduce the level to at least 500 ppm
1200 and aboveWater with this level should not be drink as it may cause serious health hazards

Hard water Vs. Soft water which one is healthier

The more are the dissolved salts in the water; the more will be its hardness. Hard water, although it is not harmful to health, it can pose a threat if the TDS level is not within an acceptable range (more than 500 ppm).

In fact, a considerable amount of dissolved minerals like calcium and magnesium are good for health. Therefore, if the TDS level is more than the acceptable range, RO based water purifier becomes essential. An RO water purifier, with the help if its RO membrane, removes the dissolved salts and brings it back to a drinkable form.

Soft water is generally treated water with very less dissolved salt, mostly sodium. The TDS value of the water ranges from 150 to 300 ppm, which is considered perfect for drinking. Therefore, in such cases, there is no need for RO water purifiers. Instead, a simple filter based on gravity can do the needful. For a better result, you can also opt to UV water purifier or activated carbon filtration process to get rid of other dissolved impurities like chlorine.
