After reading this article you will know what is RO water purifier. You will

also be able to decide if it is RO, UV or UF that is your ideal purifier. Choosing the best water purifier that suits you can be a difficult task. Which is why we have given below a detailed analysis. Here is everything you need to know before buying your ideal water purifier.

Difference between RO, UV and UF water purifiers. 

It requires electricity to purify water This too requires electricity to operate. It does not require any power.
This works only using high water pressure. Works with normal water pressure. Works with any water pressure.
Kills and filters out germs from the water.

Kills all germs without removing them.

Filters out and kills germs from the water.
Filters out dissolved salts and harmful metals. Does not remove dissolved salts and metals. Does not remove dissolved salts and metals

What is an RO water purifier? 

What is RO water purifier?.

Have you ever wondered what is RO water purifier and how is it different from UV and


RO stands for Reverse Osmosis. This technology uses RO membranes for purifying water.

RO membrane is an extremely fine cloth-like structure. It can filter out even the tiniest viruses, bacteria and germs from the water. In addition, this membrane also helps get rid of poisonous chemicals.

It protects you from water-borne diseases. Thus providing you with the purest drinking water.

How do RO water purifiers work?

How do RO water purifiers work?

RO water purifiers use a membrane that acts as a barrier between impure water and pure

water. Impure water molecules don’t pass through the membrane.

The molecules of the membrane are much smaller compared to the molecules of germs and

bacteria. This ensures that they can’t pass through the RO membrane. They are then filtered out of the system.

The passing of water happens by adding high pressure. This is known as reverse osmosis

system. It is the exact reverse of the osmosis that occurs when freshwater joins the seawater. Hence, it is known as reverse osmosis system.

Is RO purified water safe? 

It is a common notion that RO water is not safe to drink. But this might be because it doesn’t

have the minerals and nutrients required by our body. However, what we fail to address, is the fact that the amount of nutrients is normal water too is very small.

It is not worth drinking impure water just to consume these little nutrients present in them.

The lack of these nutrients can be made up by eating healthier.

What are the advantages of drinking RO purified water? 

  1. Along with killing harmful bacteria and viruses in water. RO purifiers completelyeliminate them.
  2. It converts hard water into soft water.
  3. RO water purifiers are very easy to use and maintain.
  4. With RO purified water, heavy metals and salts are removed from the water.
  5. RO water purifiers provide you with safe and tasty drinking water.

What are the cons of using RO water purifiers?

  1. RO water purifiers require electricity tooperate.
  2. For the water to be purified using RO water purifiers, it requires highpressure.
  3. It produces a significant amount of wastewater.
  4. Purification of water using RO filter takes a long time.

What is a UV water purifier? 

What is a UV water purifier?

A UV water purifier kills germs and other bacteria in the water by exposing them to Ultra-

violet rays. This is highly effective for dealing with water-borne diseases. It prevents bacteria from spreading diseases through drinking water.

As per the UV water purification procedure, water is passed through the UV radiation source

tube. Then UV radiation is exposed to the water.  This method is very effective, simple and eco-friendly.

How do UV water purifiers work? 

How do UV water purifiers work?

UV water purifying system takes place using an Ultraviolet radiation lamp. UV rays have the

ability to eliminate germs and disease-causing bacteria. They work by attacking the DNA of these bacteria and germs. Thus destroying their ability to reproduce. Therefore, proving you clean and healthy drinking water.

What are the advantages of UV water purifiers?

  1. Ultraviolet water purification is the most effective way of water purification.
  2. This method of purifying does not use any chemicals or use harmful by-products.
  3. Water purification by UV purifier uses minimum energy.
  4. Maintaining UV purifiers is easy and less time-consuming.

What are the cons of using UV water purifiers? 

  1. This method of water purification does not eliminate the bacteria or germs that arekilled using Ultraviolet Rays.
  2. Electricity is a necessity for UV water purifiers.
  3. People usually pair UV water purifiers with other methods of water purificationsuch as RO.
  4. UV purifiers have no light shutoff. Since UV lights are invisible, it is difficult toknow if it stops working.

What is a UF water purifier? 

What is a UF water purifier?

UF water purifiers work with Ultrafiltration technology. UF water purifier filters water are

similar to RO water purifier but UF pores are much bigger. However, the biggest advantage of UF water purifier is that it does not consume electricity. Without the need for maintenance, they do not only kill the bacteria and viruses but completely filter them out.

How does the UF water purification process work?

How does the UF water purification process work?

Ultrafiltration technology is very much like Reverse osmosis. However, UF does not require

electricity or high pressure. Here, the water is passed through the UF membrane, filtering out chemicals and bacteria. These membranes are much bigger than RO membranes. Therefore being able to preserve the healthy minerals in the water.  

What are the advantages of UF water purifiers?

    • Does not requireelectricity


    One of the prominent advantages of UF water purifier is that it does not consume any

    electricity. This makes it highly reliable and dependable. Which is why you do not have to suffer from a shortage of drinking water if there is a power cut. You can count on it at all times.  

    • Eliminatesgerms


    Unlike UV water purifiers, UF purifiers eliminate the germs and bacteria after they are killed.

    It removes even the tiniest viruses. They are all flushed out of the drain, after which they are filtered out using UF membranes which are bigger than RO.  

    • No annualmaintenance


    UF water purifiers stay in good condition for many years, without the need for much

    maintenance. So they do not need to be checked and repaired every year, unlike RO and UV water purifiers.  

    • Long-lasting


    UF water purifier can last longer than RO and UV water purifier, without much maintenance.

    It lasts for an average of 10 years.  

    • Durable 


    UF membranes are extremely strong. Therefore, they do not break easily and last for a long

    time. This makes UF water purifiers extremely durable.  

What are the disadvantages of using UF water purifiers?

One of the only notable disadvantages of UF water filter is that it cannot remove dissolved

salts. Therefore, if the TDS level in the water is high, UF water purifier won’t be able to purify it completely.

What is TDS? 

What is TDS?

TDS stands for total dissolved solids. It refers to the total amount of dissolved salts,

minerals and other solids present in a certain amount of water.

It defines the quality and purity of water. The amount of TDS  in the water you drink has a

huge effect on your health and well being. That is why, it is important to keep the TDS level up to 500 parts per million.

In conclusion, each type of water purifier has its own pros and cons. The ideal water purifier

for your home depends on the TDS level of the water you are drinking, so the best one would be a combination of all of these so you get the best of all worlds.

What is UV water purifier?

UV water purifiers refer to a type of purifier that uses Ultraviolet Rays to attack the germs and bacteria in the water, thus making it pure and safe to drink. 

What is RO water purifier?

RO water purifiers use Reverse Osmosis Technology to get rid of impurities in water. It uses a thin membrane that filters out even the tiniest viruses, germs as well as poisonous chemicals from water. 

What is UF water purifier?

Almost similar to RO purifiers, UF uses a thin membrane with pores, however, these pores are much bigger than RO. It does not require electricity and protects the natural healthy minerals present in water.

What is TDS?

TDS stands for total dissolved solids. It refers to the total amount of dissolved salts, minerals and other solids present in a certain amount of water.
