  • RO Water Purifier? Its Advantages & Disadvantages

RO stands for Reverse Osmosis Water purification. This technology works based on a membrane capable of filtering pollutants, dissolved chemicals, microbes, and other substances in water. Basically, any pollutant or particle bigger than the size of water is filtered out through this membrane while the finer water particles pass through the membrane.

The reverse osmosis membrane has very fine pores, as minute as 0.0005 microns. Even a single sodium chloride molecule has a size of 0.0007 microns. The membrane is capable of filtering the finest of salts and dissolved chemicals due to this fine pore size.


  • The RO technology can filter and remove chemicals like lead, arsenic, and mercury, which can be life-threatening and lead to biological disorders.
  • RO water purifiers also improve the taste and quality of water.
  • These water purifiers are low maintenance. The membranes require replacement only twice a year.

Therefore, it is advisable to combine two or more technologies together to filter your water by all means.

UV water purification systems use ultraviolet rays that kill microorganisms and pathogenic bacteria present in water. These days, water purifiers use mercury lamps that use electricity and produce ultraviolet rays. These rays destroy the microbes as well as prevent them from reproducing.

It kills the microorganisms as well as destroys their DNA. They are installed in the water purifier so that it does not come in direct contact with water either. These ultraviolet rays are extremely safe and do not alter the chemical structure of water either.

These UV rays ensure that the water is free of germs and bacteria under all circumstances and effectively makes water safe for drinking.


  • Instant water purification using UV light.
  • It helps in killing most forms of germs and bacteria from the root level.
  • No chemicals or harmful methods used for the purification
  • Extremely beneficial in combination with RO water purification system


  • It does not improve the taste of water
  • Does not allow rays to pass through if water is turbid
  • Requires high amount of electricity, not as cost-effective
  • Gravity Base (Non-Electric) Water Purifier? Its Advantages & Disadvantages

Gravity-based water purifier systems are the most cost-effective and one of the safest purification systems. It uses Ultra Filtration technology to remove gravels, dissolved particles, as well as bacteria and cysts. It can also expel harmful chemicals like chlorine, fluoride, and other dissolved salts from water.

Large industries and setups rely on gravity-based water purification systems as they are cost-effective and provide suitable purification.


  • Gravity based water purifying systems are portable
  • Does not use electricity, cost-effective
  • Safe chemical free disinfecting system


  • Cannot remove extremely minutes particles that are micron-sized
  • Does not kill bacteria from DNA level like Ultra Violet rays
  • Multistage Water Purifier? Its Advantages & Disadvantages

Water purifiers these days have evolved and combine multiple technologies to make sure that the water is safe to consume in all ways. For example, most water purifiers these days are equipped with RO + UV + UF technologies.

Here, the water passes through a normal sediment filter that removes all the gravel and huge particles and dust in the water. Then the water is given some pressure through a pump to pass through the RO membrane. The RO membrane makes sure to remove the finer particles and microorganisms that cannot pass through the membrane pores.

Once the TDS and microorganisms are removed, then comes the Ultra Filtration or UF stage. This is like a second layer of RO membrane and combines sediment filter technology to scan through the water and expel the fine particles and sediments. Again, it helps in reducing the TDS levels of water.

Finally comes the UV filtration stage, where the water is exposed to Ultraviolet rays killing all the pathogenic bacteria and making the water free of microbes and dissolved particles.


  • Water is totally safe to consume
  • Water tastes better and does not appear turbid
  • Kills pathogenic bacteria from the root level
  • Reduced TDS levels of water


  • The combined technology can be expensive
  • May require time to time maintenance based on your water supply
  • Removes some essential minerals from water that are essential for the body

2. Source of Water

In India, there are various sources from where water is supplied to households. The common sources include:

  • Municipal Corporation Supply
  • Borewell water supply
  • Water from rivers or dams
  • Small lakes and ponds or other local water bodies

Each water source can have different types of impurities based on the location of the water source and other environmental factors.

Water from rivers and lakes have high amounts of impurities that are dangerous and pathogenic. This is because livelihoods across the lakes and riversides are majorly responsible for contaminating the water. Water from such sources can contain bacteria and cysts. Therefore, if your water supply is from a lake or river, you need a multistage purification system as it can have all sorts of impurities.

If your water supply is from the municipal corporation or the borewell, these sources ensure that harmful bacteria are killed by adding chemicals. However, high amounts of these chemicals can also be equally dangerous.

Therefore, to remove these dissolved chemical molecules from water, you need RO or UF filtration systems. You can read a lot more about TDS and water impurities in the further sections.

3. According to Types of Impurities

Different sources of water have different types of impurities. These can range from chemicals, bacteria, and other human contaminants. If you get water from any of these sources, then you must consider a water purifying system accordingly.

Here is a list of the common water sources in India and the types of impurities they possess:

  • Municipal or Corporation Supply: This type of water supply may contain sand, gravels, dust, metals and other such particles. Depending on the environment, it can also have impurities like bacteria, cysts, viruses, etc.
  • Rivers: River water supply can commonly contain mud, sand, etc. It may also have salts like Calcium, Magnesium, etc, or even heavy metals like Lead, Arsenic, Fluoride, Mercury, etc.
  • Borewell/Groundwater: Borewell water supply can also contain mud, sand, calcium, magnesium, lead, arsenic, and other harmful heavy metals.
  • Lakes/Ponds: Water supply from lakes and ponds have the highest amount of impurities. They can have various bacterial growth, protozoa, cysts, mud, sand, algae, etc.

4. According to TDS Level of Water

TDS level is the total dissolved solid content of water which determines the amount of all dissolved solids. These dissolved solids can easily pass through membranes having a pore size of 2 micrometers or smaller.

It is very easy to find the TDS level of water with the help of a digital TDS meter. These TDS meters are readily available online at very affordable prices. The TDS meter measures the number of dissolved solids in Parts Per Million (PPM) or mg/L.

However, the TDS meter does not tell you what kind of dissolved solids are present and the concentration of each solid particle.

It is essential to know the concentration of each solid because your water supply may contain certain less harmful and more harmful dissolved solids as well. Water supply may contain salts like calcium, magnesium, potassium, sodium, etc., that are permissible up to a certain limit.

However, depending upon the source of water, it may also contain harmful metals like lead, arsenic, fluorides, nitrates, etc. If your water supply comes from particular sources like near industries, or farmlands that use chemical fertilizers and release wastewater in water bodies, then the TDS level can be high as well as dangerous.

The desirable TDS level for any water supply is 500mg/L. The permissible limit is up to 2000mg/L. But water supply from different sources can have different permissible limits. In India, the permissible limit based on different water supplies is around 10500mg/L.

Therefore, knowing the individual constituents is important to decide whether the water is safe for drinking and which purification technology to use.

Here is a list that should help you make your decision easier:

Water Supply having TDS below 500ppm:

  • Below 500 ppm with no mud and biological impurities: Gravity based water purifiers
  • Below 500 ppm with biological contaminants and no dirt: UV based water purifiers
  • Below 500 ppm with dirt and no biological contaminants: UF water purifiers
  • Below 500ppm with dirt and biological contaminants: UV and UF based water purifiers

Water Supply having TDS above 500ppm:

  • Above 500ppm with no mud and no biological impurities: RO purifiers
  • Above 500ppm with biological contaminants and no dirt: RO + UV purifiers
  • Above 500ppm with muddy water and no biological contaminants: RO + UV + UF water purifiers
  • Above 500ppm with muddy water and biological impurities: RO + UV + UF water purifiers

5. Tank Storage Capacity

Each water purifier these days comes with a storage tank that gives you access to purified water at all times. Based on the size of your family, you should go for a water filter with high storage or tank capacity. Even if you have frequent power cuts in your area, a water purifier with high storage capacity always helps.

These days water purifiers come with a tank capacity of around 7 to 12 liters. So based on your requirements, you can choose one accordingly!

6. Purification Speed

The purification speed is determined by the amount of water purified in an hour and stored in the tank. Most water purifying devices these days have a rate of 12-15 liters per hour which is considered ideal for Indian households.

But again, if you have a larger family or frequent power cuts, you would need quick access to purified water due to high water consumption.

Some water purifiers even offer a purification rate of 20 liters/hour. You can choose one based on your requirements.

 7. Installation Type

Most water purifiers these days offer the flexibility of being wall-mounted or even placed on the counter. Based on your space in the kitchen or anywhere at home, you can either suspend it or place it on your platform.

Wall mounting is space-saving, but there are under-the-sink options available too. This allows you to install the divide below the kitchen sink, which is space-saving.

However, you will have to bend and access the purifier at all times. Therefore, we suggest wall mounting being a convenient option for water purifiers.

8. Indicators and Alerts

Indicators are an essential feature to look for in water purifiers. You need to know whether the water is appropriately purified as per the technologies mentioned for the water purifier.

Supposedly, the UV lamp stops functioning or the UF filter is not working, then the alerts and indicators warn you that it is time to change the filter.

You must also look for indicators that alert you when the tank is full or if the purifier’s purification process is going on.

This is a highly overlooked aspect of any water purifier but very significant for indicating the purifier’s performance.

9. Warranty and After-Sales service

Water purifiers require regular maintenance and cleaning. There can be tiny spare parts and devices within the purifier that may get spoilt or the filter may require regular cleaning.

Especially in combined water purifiers, there are chances that the indicator or UV light may get spoiled or any of the filters may start malfunctioning due to extremely poor water quality.

In such times, water purifiers that come with a good warranty and after-sales service reduce the burden and expenses for a few years. You can also look for water purifying companies that offer extended warranties for a hassle-free operation.

RO vs. UV vs. Gravity Based Water Purifier: Which is Better?

Reverse Osmosis (RO), Ultra Violet Filtration (UV), and Gravity Based Purification or Ultrafiltration (UF) helps in removing different types of impurities from various water sources.

However, if you are new to the concept of water purifiers, you must understand which purification technology is the best for your household. For which it is essential to compare the various technologies used in water purifiers these days.

Read on to know.

RO Water Purifiers:

  • Works on electricity for purification
  • Filters viruses and bacteria from water
  • Removes harmful chemicals, dissolved ions, and salts, as well as metals
  • Also helps in removing mud, gravel, and dust
  • Reduces TDS levels by 90%
  • Requires water in high pressure for purification. Hence you need to install additional pumps to increase the pressure.
  • Size of the membrane for filtration is tiny, approximately 0.0001 micron

RO water filters can help filter monovalent ions, multivalent ions, viruses, bacteria, and suspended solids.

UV Water Purifiers:

  • UV water purifiers take up a lot of electricity for the UV light to function
  • It kills viruses and bacteria but does not remove their dead cells and remnants from water
  • Does not remove other solids, metals, and harmful chemicals or salts like RO membrane
  • Works with normal water pressure as well
  • No membrane for filtration
  • No TDS reduction or removal

Apart from killing viruses and bacteria, UV filters do not filter out any chemicals, gravel or solid substances, salts, etc., from water.

Gravity based water purifier:

  • It does not require electricity for filtration
  • Can remove viruses and bacteria from water that are larger than 0.01 micron but does not kill them
  • Does not remove harmful metals and chemicals in the water
  • Can filter dissolved solids, mud, gravel that are larger than 0.01 micron
  • Works in normal water pressure
  • No TDS removal or filtration

Ultra Filtration or Gravity Based Water Purifier can help eliminate viruses, bacteria, and suspended solids that are large. However, it cannot filter chemicals and salts, unlike RO water purifiers.

Therefore, if you compare the three types of water purification systems, neither one is totally efficient in filtering water. While RO may prove to be the best filtration method among the three, it does not kill viruses and bacteria, and a few of them can still remain in the water.

Therefore, for best results, we suggest combining all three water purification technologies as each filtration method has its own significance.

How to Make Your Own Water Filter?

In the good old days, technology was not as developed. Therefore, before the advent of water purification systems, people used to still consume purified water. But through natural means and not by using hi-tech purification technologies.

There are several natural ways through which you can purify water and make your DIY water filter. Here is the simplest method you can try.

Things you will need:

  • One plastic bottle of 500 mL
  • One medium plastic container
  • One large plastic container
  • Plastic tap to attach to the filter
  • Glue
  • Gravel/Coarse sand
  • Cotton
  • Charcoal (crushed)
  • TDS meter (optional)
  • Drill/Sharp Cutter
  • Funnel

21 Steps to make your own water filter:

  1. Take a 500mL empty plastic bottle and remove the cap.
  2. Next, make a few holes at the bottom of the plastic bottle using a sharp object or a drill.
  3. Now, we will be making multiple layers of materials required for filtration. The water will pass through each material, undergoing different filtration layers.
  4. First, we use some cotton and stuff it at the bottom. Stuff and pack the cotton adequately.
  5. Next, we make a layer of crushed charcoal. Pour some charcoal on the top of the cotton layer inside the bottle using a funnel. Make sure the pieces are well crushed.
  6. The next layer will include sand/gravel. Pour some sufficient spoons of sand or gravel over the charcoal layer using a funnel.
  7. Lastly, stuff the top of the bottle with some cotton.
  8. Cap the bottle with the lid.
  9. Make around 4-5 holes in the lid to allow the water to pass through the bottle.
  10. Now, we make use of the medium plastic container. First, create a hole using a drill or a sharp cutter around the size of the bottle cap.
  11. The bottle should easily be able to enter the container. Check once and seal the attachment with glue.
  12. Next, we take a large-sized container and make a hole that is the size of the lower portion of the bottle. Also make a hole towards the face of the container to insert a plastic tap to access the water.
  13. Once the hole is made, fit the bottle inside.
  14. Your arrangement should look like this, starting with the medium container, with the bottleneck fit within. Next, the bottle base passes through the large container that will contain the filtered water.
  15. You will need to attach a tap at the hole you made on the face of the large container in the front.
  16. Now, fill the medium container with a good amount of water right to the brim. The more the water pressure and flow, the better the filtration.
  17. Since the water is at a height, the water passes through the multiple filtration layers in the plastic bottle.
  18. The clean water starts filling up in the large container.
  19. You can empty the large container using the tap fixed in front.
  20. Continue the process for the amount of water you want to filter by refilling the medium container on top.
  21. You will notice the dust and dirt particles settling at the bottom in the medium container. The difference between dirty water and clean water can be seen visually and also measured using a TDS meter.

This is the most basic and very effective way of obtaining filtered water that is fit for drinking. However, it is not safe for water obtained from industrial let-outs or ponds, lakes, etc., containing viruses and harmful chemicals.


1. Should we drink RO water?

Not always! RO water removes all the impurities and salts from water, including essential salts like Calcium and Magnesium, or Copper. Over time, it can weaken our bodies as we don’t obtain the vital minerals required from water. Therefore, drinking only RO purified water can be harmful in the long run.

2. How can I check my home water TDS?

You can check home water TDS by using a TDS meter. This is easily available online or at any local store that helps you determine the number of dissolved solids in your water supply. Each type of water has a different TDS level which can vary from different sources. If the TDS level is greater than 1200 mg/liter, the water is unsafe for drinking.

3. Which is better, UV or RO?

Both! While RO eliminates viruses and bacteria from water and harmful chemicals, it does not essentially kill the pathogenic cells. The tiny cells can still remain in the water in dormant forms and enter the body if not destroyed. Therefore, UV and RO technology both are essential in a water purifier.

4. Is low TDS water harmful?

No! Low TDS water is not harmful to the body. However, it may not contain the essential salts usually obtained from water, making it less efficient over long-term consumption.

5. What is the TDS of Bisleri water?

Bisleri maintains a TDS level up to 120 ppm, making it extremely safe to drink.

6. Is bisleri RO water?

Yes! Certain studies have claimed that Bisleri maintains a TDS level of 120 ppm and is RO purified water. It has some added minerals that lead to the patent taste of the branded water.

7. Is RO banned in some countries?

Yes! It has been proven that RO eliminates useful chemicals like zinc, copper, magnesium, etc., from water and drops the TDS levels of water drastically. Therefore, it has been banned in certain countries.

8. Is 100 TDS water safe for drinking?

Yes! 100 TDS water is safe for drinking and causes no side effects. However, one needs to ensure that it has the essential minerals before consuming water with TDS levels of 100 ppm.

9. Is TDS the same as PPM?

TDS is measured as a volume of water with units mg/L, which is also known as parts per million or ppm. It is a unit for measuring the levels of dissolved solids in water.


With the rise of diseases and the advent of pandemics, water purifiers are the need of the hour. However, each purifier comes with a vast range of technologies that can make it confusing to choose the best water purifier.
