Why You Need a Water Purifier | Advantages & Disadvantages of Water Purifier

The water purifier has now become a necessity in Indian households. We are not sure from where our water comes from and is it clean or not. If it’s groundwater or water tanker, it may contain pesticides, heavy metals, bacteria, and high Total Dissolved Solids(TDS).

Advantages of Water Purifier

Here are some advantages of having a water purifier:

Clean & Healthy Water

In today’s world, there is so much water pollution due to plastic waste dumping in water bodies. And, unfortunately, we get water that contains plastic toxins and other harmful contaminants. And, the best water purifier removes all the harmful contaminants and make it safe, clean, and healthy for you.

The Water Tastes Better

The uncleaned water taste salty which is unhealthy whereas the purified water has a different taste. So, always check reviews or ask your friends and family who have the best water purifier, ask them about their experience, the taste of water, and then buy the best one for your household.

Reduces the Risk of Cancers Significantly

Chlorine is useful in cleaning water as it is the cheapest way to clean it. But, that is the safest method as it can cause cancer. But, if you drink water from the best water purifier, which is free from chlorine, it reduces the risk of cancer in your body.

Convenient & Easy to Maintain

The best water purifier is easy to install, maintain, and clean. Instead of getting big filters of water from the market, just install the best water purifier.


If you are getting filters every day, then it must be costing you so much and it may not necessary that your water is completely purified. But, having a filter gives you surety that your water is completely purified and bacteria-free, and economical too.

Overall, a water purifier cleans water as well as makes it safe by removing bacteria that cause diseases like cancer, diarrhea, typhoid, and cholera. Now, let’s have a look at some of the disadvantages.

Disadvantages of Water Purifier

Now, let’s check the disadvantages of water purifier:

Energy Consumption

Water purifiers consume energy in operation as well as production. The processes such as ultraviolet filtering and reverse osmosis rely on electricity.


The process of purification takes time. The customer has to wait for some time to make the water drinkable.

These are some disadvantages of a water purifier, but it is very little in comparison to the advantages a water purifier has. Now, let’s see the working of the water purifiers and the process of purification.

Types of Purifier & How does Water Purifier Works

Mainly, there are 4 types of water purifiers.

  1. Reverse Osmosis(RO)
  2. Ultraviolet(UV)
  3. Ultrafiltration(UF)
  4. Activated Carbon
  5. Sediment filter

Let’s discuss their pros, cons, its working and lastly understand which one would you go for.

Reverse Osmosis

The most widely used method by companies is Reverse Osmosis(RO). The Reverse Osmosis method work in the following ways:

  1. The water is forced through a membrane to eliminate the impurities that may not be visible to the naked eyes.
  2. The membrane removes the impurities based on its shape and size. In simpler words, particles larger than water molecules can’t pass through the membrane. It blocks all the chemicals and bacteria.
  3. The membrane can also remove the dissolved chemicals from water which other purification cannot.

Advantages of RO

  • The RO removes solid, metal particles, germs, bacteria, and other contaminants. 
  • It improves the taste and odor of water by removing contaminants that cause bad taste.
  • It is cost-effective and easy to maintain.

Disadvantages of RO

  • The disadvantage of the RO is, it requires electricity to work.
  • It produces water waste. To filter 10 liters of water, it wastes approx 5 liters of water. 


Ultraviolet is another purification method in water purifiers. Let’s see how UV Purifier works:

  1. The UV rays penetrate bacteria in water and destroy the DNA of organisms. This eliminates the ability to reproduce the organism.
  2. It is a very simple and effective process for water cleansing as it destroys 99.9% of germs without adding chemicals.
  3. Generally, UV water purification systems are used with another form of filtration like RO.

Advantages of UV

  • The UV has a low maintenance cost.
  • The water purifier is capable to purify 2 to 4 liters of water in a minute. Whereas other water purifier takes few minutes to purify a liter of water.
  • It consumes very low energy consumption, as much as a bulb.
  • If you have a storage tank, then it requires cleaning twice every week, whereas, without a storage tank, a water purifier needs almost no manual cleaning.
  • UV does not use chemicals and doesn’t alter the taste and odor of water.
  • The purifier doesn’t remove the essential minerals from the water.

Disadvantages of UV

  • The germ’s bodies remain in the water. If the germs don’t been affected by the UV rays and reproduce themselves again, it can cause many diseases in our body.
  • If the water has a bad smell or state, it will not be changed, as the UV doesn’t change it.
  • Not effective on mud water. Some sand particles can pass the UV light.
  • It is not effective in purifying groundwater. It is only designed to purify low TDS water like lake and river water.


The process of Ultrafiltration water purification is as follows:

  1. Ultrafiltration is a membrane in which pressure is forced.
  2. Due to this pressure, the bacteria and germs get out of the water. 
  3. It was only used for desalination earlier, but as time flew, the membrane is made to remove bacteria and all other microorganisms and contaminants.

Advantages of Ultrafiltration

  • The UF water purifier works without electricity.
  • It also works well even in low water pressure conditions.
  • UF purifier doesn’t use chemicals that give you chemical-free water.

Disadvantages of Ultrafiltration

  • The filtration is not effective in hard water. It can’t emove dissolved solid from hard water like groundwater.
  • As the germs are trapped in the purifier, frequent cleaning is required.

Now, let’s see the fourth method of purification, Activation Carbon.

Activated Carbon

As the name suggests, an activated carbon water purifier uses carbon, which is activated charcoal. The charcoal works through the process of adsorption. Adsorption holds the impurities on the surface of the filter. 

It removes toxins, without removing salts ad important minerals. But this filter needs to be replaced every 12 months as impurities are kept in the filter.

Advantages of Activated Carbon

  • It removes toxic chemicals like Chlorine and heavy metals from water.
  • After purification, the smell and taste of water become good.
  • If used with RO membrane, it makes the life of the RO membrane longer by stopping chemicals like chlorine to reach the membrane.

Disadvantages of Activated Carbon

  • The purifier cannot remove dissolved solids and salt from the water.
  • It can just remove chemicals and metal and can’t remove bacteria and viruses.

Sediment filter

A sediment filter works on a process called a mechanical filter. A mechanical filter works as a mesh. It allows water to pass but stops dust. Sediment filters are the net that catches the particulate matter traveling in your water. 

Advantages of Sediment filter

  • The filter removes rust, mud, dirt, and dust particles present in water.
  • As it removed all solid particles, it protects RO, and UV purifiers and increases their lifespan.

Disadvantages of Sediment filter

  • The filter can’t remove dissolved solids, heavy metals, and germs like bacteria, viruses.
  • Cannot be used independently, as the filter needs UV and RO filter to remove other germs and bacteria.

Now, let’s see the best water purifier for your household.
