Things To Know while buying the best water purifier for your home.

Our health mostly depends on what we eat and drink. There is a saying that, we can live without eating food for around 21 days but, without drinking water, it is impossible to survive even for more than 2-3 days.
“There’s over a billion people on this planet that don’t have access to clean drinking water.” – Michael Moore
“My secret is one the world needs to know – nearly a billion people a year die from unsafe drinking water.” – Bella Thorne

Water plays a vital role in all our bodily functions. Thus, it is paramount that you constantly replenish your body’s water reserves. With the pollution levels rising and the changing climate every few kilometers, enquiring for a RO water purifier price is necessary in the modern times. Selection of a right water purifier is not an easy task. In a developing nation such as India, Finding the best water purifier for clean and healthy drinking water is a need because of the numerous impurities present in the water. So here is a complete guide to know and pick the best water purifier for home.

·  Kind of water Supply:  This is the first deciding factor for best water purifier and source of water should be observed carefully because this will decide whether your water needs removal of dissolved salts that are not required by the body or your water contains germs and viruses which will affect your health. Eventually, the water that reaches us is contaminated with the impurities and toxins of the industrial waste along with other harmful contaminants. Generally, the water supplied from many sources like lakes or rivers usually contain slight amount of contamination, germs, bacteria, viruses which is enough for giving birth to water-borne diseases such as Cholera, typhoid, Hepatitis A, and dysentery etc.
·  Type of Water (Hard/Soft Water): Example sources of hard water are underground water, water drawn from bore wells, or water supplied from tankers. Hard water may contain fluoride, arsenic, and other heavy metals.
The example sources of soft water are river water, lakes, rain harvesting, or water supplied by municipality.
·  TDS Level: We heard a lot about TDS (Total Dissolved Salts) which helps to calculate hardness or softness of the water. Water contains lots of dissolved impurities and salts which are harmful to body these should be removed from the water before drinking. There are many heavy metals like arsenic, mercury and lead present in water which should be removed because our body can never get rid of these metals and they keep on accumulating causing health problems in the longer run and short life span. RO purifiers can easily convert hard water into soft water and make it fit for drinking.
There are so many TDS meters available in the market or you can purchase TDS meters online from Amazon and Flipkart at very affordable range from Rs. 300 – Rs. 1000 to measure the hardness of water.
ü  Below is a table showing TDS level hardness.
TDS Level
Water Hardness
Very Soft (Ideal for drinking)
Soft (might be used for drinking)
Hard (use RO Purifier)
Above 400
Very Hard (use RO + UV Purifier)


ü Water Purification Technology: Water purification technologies are getting advanced every day and we have various kinds of water purifiers in the market like Reverse Osmosis, Ultra-Violet, Ultra-Filtration, Gravity Based Water Purifiers, Ultra-purification and RO + UV water purifiers. With such grave health hazards around you, it becomes even more important for us to be aware of different purification system and best available water purifiers to ensure pure and sterilized healthy drinking water:

    Reverse Osmosis (RO):
    Reverse Osmosis (RO) is widely used technology to purify water containing a high level of salts in water and make it unfit for drinking. In this method water is passed through a semi-permeable membrane under high pressure to remove dissolved impurities. RO purification is mainly used for Salty, Khara or Hard water. This technique requires electricity to purify water and produce lots of waste water.

UV System Diagram (Source: Quora)
Ultra-Violate (UV): UV is water purification method to remove germs, bacteria and viruses from water. This technique uses a Rod producing ultra-violet radiations which are made to pass through water so these radiations can kill germs, bacteria, and viruses present in water. This method also requires electricity but do not generate waste water. However these cannot remove heavy metals like arsenic from water.

Ultrafiltration Membrane Filtration Principle (Source: Quora)
Ultra-Filtration (UF): Ultra-filtration method uses threads of fibers to remove hardness from the water up to a certain limit. In this method water is passed through microfibers threads which remove salts from water. This method is adopted by plants and trees using its roots as fibers to filter ground water.

4. RO+UV Technology: Some of the Water purification brands employ both the RO and UV technologies in the same water purifier. These types of water purifiers can work with all kinds of water. Always, purchase an RO + UV water purifier that comes with a TDS regulator. Double check the Total Dissolved Solids (TDS) Levels.

ü Types of Water Purifiers: Going to the store and/or buying any water purifiers online is not enough, you must choose the best water purifier for home. Because it is not just like any other appliance in your kitchen, the health of your family will be dependent on your selected water purifier.

RO purification process can remove Heavy Metals, Pesticides, Arsenic, Flouride, Cadmium and other toxic dissolved salts present in the water. Electricity is required to operate an RO Water purifier. Conventional RO Water purifiers will remove natural minerals along with toxic dissolved salts. So, make sure you buy an RO water purifier that comes with a TDS controller which retains Natural minerals in the Drinking water.

UV Water Purifier: UV water Purifiers are generally used to make water free from germs, bacteria and viruses preventing water-borne diseases like cholera and dysentery.

UF Water Filter (Source: Zelect)
    UF Water Purifier: UF water purifier uses hollow fiber membrane. When water passes through these fiber membrane, suspended solids, other impurities are retained in fiber. UF does not kill pathogens or microorganisms. It effective only when it use with other water purification technologies. UF works without electricity and does not use any chemicals. It is similar to RO and does not need electricity to operate. These type of water purifiers uses a very fine membrane to kill the bacteria, cysts and other microbes present in the water and functions very efficiently when used with the public supply water.
Gravity based Water Filter (Source: Quora)
Gravity based water purifier : These purifiers simply filter water with the difference in pressure. Many people choose to buy such a water purifier because it does not need electricity to operate, and are relatively cheaper.


Activated Carbon Water Filter (Source: Zelect)
    Activated Carbon Water Purifier: Activated carbon water purifier made up of charcoal granules, absorbs pesticides and herbicides. Activated Carbon Water Purifier works without electricity. Activated Carbon Water Filter works by removing chemical such as chlorine in water when passing through carbon granules and improves the taste of water and removes bad smell.

6. RO + UV Water Purifiers: They can be used for sources containing hard water as they remove extra salts and kills germs from water making it safe for drinking purpose.

Multi-stage (Universal) Water Filter Process (Source: Quora)
Multi-Stage (Universal) Water Purifier:combination of purifying technologies in this method different purifying technology is used to filter water. Universal Purifiers which can be used with any type of water without worrying about the supply of water they use RO + UV + UF purification technology to give best clean and pure water. These purifiers are fully automatic, check the water level and then apply purification technique to clean water. 

So, these are the water purification technologies and different kinds of water purifiers India has available in the market. Now you might have confused to choose the best water purifier for home. Let’s make this confusion simple:
  • If the water is hard and have high contamination, consider RO + UV purifier.
  • If the water is hard and low contamination, consider RO purifier.
  • If the water is soft and have high or low contamination, consider UV purifier.


    Looking for storage capacity is also important as it will tell you about how much water an RO water purifier can store. This becomes important in such areas where power cut is always an issue. For a small family, water storage capacity of 8-9 litres will be enough as the water will be continuously refilled as purification starts.

RO Membranes (Source: CompareWaterPurifiers)
RO membrane is the most important part of the RO water purifiers as it defines what type of impurities can be removed from it. The pore size of the membrane plays a vital role in filtering out the impurities. RO membrane has a pore size range of 0.0001 – 0.001 microns. This pore size indicates that it is the only membrane that can filter out metallic ion and salts from the drinking water such as lead, arsenic, mercury, iron, fluoride etc.

Brand selection is very important because purifiers need service in every 2-3 month of duration so a company with best after sales service is a good choice because it feels very bad if customer relation of a company is not good. Also, big brand cost little more but their products are reliable because they use the best quality of membranes and filters running for a longer period of time giving better results. Every water purifier company claims that they offer best purified and safe drinking water in the market; therefore, it became difficult to choose the best RO water purifier. Moreover, it is the certifications honored to the water purifier brands that makes it authentic and trustworthy. So, always choose the water purifier that has been certified by renowned laboratories of the world.  NSF, WQA, ISI and CE are some of the best certification given to any water purifier.
