Best Water Purifier Buying Guide India
These 5 points below will tell you about what kind of water supply is needed for water purifier. What TDS levels are good for your health. Go through these 5 points to get the clear idea of what are basic reasons to purchase the water purifier and how should you enquire yourself!
1. What kind of water supply is coming at your home?
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. There are some heavy metals like
lead, mercury, arsenic etc. which needs to be removed from water because the human body cannot get rid of these heavy metals and they keep on accumulating in the body causing health problems.
Water from many sources contains germs, bacteria, viruses which cause water-borne diseases like cholera, typhoid and dysentery etc. We should cleverly choose our water purifier although it might cost some burden but in the end, it will keep you away from doctors and costly medicines having side effectson the body. Below is a table to show what are different kinds of water supply present in India with some suggestion for water purifiers.
| Water Supply | Germs Level | TDS Level | Purifier Type |
| Underground water, Borewell or water supplied from Tankers | High in Bacteria and viruses | High TDS (Hard Water) | RO + UV |
| Underground water, tube well or Salty water | Low bacteria and viruses in water | High TDS (Hard Water) | RO |
| Surface water from rivers, lakes or rain harvesting supplied by the municipality | Low bacteria, viruses, germs in water | Soft water | UV |
2. What is TDS level or Hardness of water
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 leadpresent 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.
Now you must be thinking how to check the
TDS meter available in the market which will measure the hardness of water or you can purchase online, these meters are not very costly it might range from Rs. 300 – Rs. 1000 online check
HM TDS-3 meter mostly used by people because of its accuracy. HM TDS-3 meter is the Best water purifier testing meter, it also shows temperature.I would strongly recommend purchasing TDS meter because it will not only help to make an easy decision for purifier it will also help you every month to check your purifier performance. Below is a table showing TDS level hardness.
hardness of water. There are
| TDS Level | Water Hardness |
| 0-80 | Very Soft (Ideal for drinking) |
| 80-150 | Soft (might be used for drinking) |
| 150-400 | Hard (use RO Purifier) |
| Above 400 | Very Hard (use RO + UV Purifier) |
If you are living in metro cities then even air is not good to breathe. Toxic levels of air are raised much higher and it is advisable to install an air purifier in the home so you breathe fresh air and add more days to your life.
3. Different Kinds Of Purifying Technologies Present In The Market?
- RO (Reverse Osmosis) this 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 wastewater.
- UV (Ultra-violet) is water purification method to removes 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 and viruses present in water. This method also requires electricity but do not generate waste water.
- UF (Ultrafiltration) 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 groundwater.
4. Which Purification Technology is best for your home?
Based on these purifying technologies different kind of water purifiers is available in the market related to impurities and water supply.
- RO water purifiers are mostly used by people and companies to ensure water does not contain high salts harmful for the body they use a different kind of membranes to purify water.
- UV water Purifiers are generally used to make water free from germs, bacteria and viruses preventing water-borne diseases like cholera and dysentery.
- Gravity-based water purifiers are mostly used in the areas facing electricity problem. These purifiers are totally based on Pressure difference, water from higher chamber moves to lower chamber fitted with germ kit and filters in-between these chambers to purify water. Gravity water purifiers can only be used for soft water containing a low level of dissolved salts since they do not use electricity purification level is not very good. These purifiers are available at a lower price range Rs. 1000-4000 in the market.
- A 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. RO + UV 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.
