Review Ultimate WATER PURIFIER Buying Guide.!

Hey guys...! I wanted to buy a Water Purifier recently... and call it a habit.. But I NEED to EXTENSIVLY research something before Buying. So.. I thought Let's share my research.

Most of us just drink RO Water without even knowing what we are drinking. In Most cases.. The RO Water we drink is just a tasteless liquid which has no health benefits at all but just a medium to quench our thirst.

This is a comprehensive Guide covering most of the aspects one should look at before Buying a Water Purifier. I Focused upon HEALTH instead of fancy Features.

First Confusion is always about.. What to Choose...eh..? I mean.. there are SEVERAL VARIANTS..! RO.. UV... UF... NF... Alkaline... Copper... and even their SEVERAL Combinations..!!!! :eek:o_O.

FIRST AND MOST IMPROTANT STEP :

If your TAP Water TDS is Below or around 200 mg/l --> UV + UF Combination.
If your TAP Water TDS is above 300 mg/l --> RO+UV+UF+ TDS Controller Combination. ( Set Water Output TDS above 150mg/l ).

If your TAP Water TDS is above 800 mg/l --> RO+UV+UF Combination.

Explanation.



1. Before Buying.. Always.. and I mean Always Check the TDS of you Tap Water. You can use any TDS metre available on Amazon ( around INR 250 ).

Now.. If your TDS is around or below 200 mg/l... YOU DO NOT NEED RO.. I REPEAT.. YOU DO NOT RO. Why.. ?? .... cause RO is a process that removes most of the ( Around 90% ) TOTAL DISSOLVED SOLIDS / SALTS ( TDS ) from your water and makes it slightly ACIDIC in nature. And as you know.. Human Blood is slightly Basic in nature and thus drinking acidic water on a regular basis increases acidic content in your body.. making your immunity slightly weaker. If you use RO in this case. Your Output Water will have a TDS around 20 to 50 AND PLEASE READ THIS CAREFULLY... PLEASE DO NOT DRINK ANY WATER WITH TDS BELOW 150 mg/l on a regular basis ( EXCEPT COCONUT WATER which has a surprisingly high TDS OF MORE THAN 1000 mg/l ) If you really care about your health. :). You can see this article. Also. do note that TDS around 300 mg/l is excellent for you health ( WHO Report ).

Now.. it's clear You DO NOT need RO if your water TDS is around 200 mg/l. Still.. It may contain some impurities as well as harmful bacteria. So.. You will need a UV ( for organic impurities ) + UF ( For inorganic impurities ) Combination in this case.

2. If your TDS is above 300 mg/l --> Go for a RO+ UV +UF + TDS Control Combination. Because.. even in this case.. RO will decrease your TDS to around 50 to 70 mg/l... BUT here.. You also HAVE A TDS CONTROLLER.
Now remember... A Water Purifier works on several steps. First Water passes through Several Filters.. then through RO Membrane.. Then through UF Membrane.. then UV.. and other membranes if any and finally in the Storage tank.


Here.. the TDS Controller bypass some of the water directly to UF Membrane instead of passing it through RO and then add that water into the output of RO Membrane... thus increasing TDS by adding original Salts present in the Tap Water. So.. your Output TDS will be whatever you desire below your Tap Water TDS. I recommend above 150 mg/l.

3. If your TDS is Way above 300 mg/l.. I mean like 800mg/l or above
.. you DO NOT NEED TDS Controller... as After RO Process.. your Output will be around 150 mg/l or above. So.. Go for a RO+UV+UF Combination.


NEXT STEP :

Electrical Type.. / Mechanical Type / Or a Combination of Both.

Answer is simple.. A combination of both BUT Please do note that some Electrical Water Purifier DO NOT allow Water Output when there is a power cut even if Water is present in the storage tank. So.. check before buying.

NEXT STEP :

Mounting Type... / Table Type / Undersink Type.

It really depends on your preference. Mounting Types are Wall Mounted.. Table Types are put on the table... and Undersink types are used in households having smaller kitchen or no space for wall mounting and table.

NEXT STEP :

Storage Tank Material:
More than 95% of the Water Purifiers use FOOD GRADE PLASTIC as a Water Storage Tank. But a few also use Stainless Steel. Some Water Purifiers that offer Hot Water Output have a combination of both Food Grade Plastic ( For Normal Water Tank ) and Stainless Steel ( For Hot Water tank ).... I would suggest to go for Stainless Steel. Still.. it's my personal opinion.. rest is your choice.

Stainless Steel Storage Tank Water Purifier.

NEXT STEP :

Alkaline Membrane
or Copper Membrane or Both.

This is also the most confusing part. Alkaline Membrane can be used if you are using RO... as it adds some basic salts in your RO Output Water increasing it's basicity as RO Water is slightly acidic in nature.
The Problem is there is no hard evidence that such water is really good for health. Some studies have shown that such water really helped many people to gain better health.. even removing joint pain... while other studies have shown no conclusive results. So.. it's your preference.


Now Copper Membrane is just a marketing gimmick. Don't go for it. Rest is your choice.

CRUCIAL STEP:

Sales After Service and Yearly Charge.
Many Companies like Kent or Pureit.. provide better service in some areas only. IN MY AREA.. KENT SERVICE is ABSOLUTLY pathetic. So.. please consult your neighbours or even online about the service of the company.
Also.. some Water Purifiers have an annual charge as high as 5K ( For Filters and Membranes ) while some has around ( 2K .. The minimum I Saw ). So.. check this beforehand.

That's it... follow these steps and gift yourself and your family a healthy Water Purifier. Again.. it's not a comprehensive guide.. as there are several features.. like Hot Water or Cold Water Output or fruit washer or Digital Display...and many more ... that today's Water Purifiers offer. And it's very important not to favour such fancy features over health. Please Prioritize You health.. and then your environment.

Finally.. Keeping all of the above in consideration.. I have decided to Go with BePure.
Now.. you must be thinking.. what's BePure..? Never heard of it...!???

Bepure is actually an Indian Startup providing Water Solutions. It has even won Silicon India Award and has many favourable reviews online.
So.. I am buying it's Bepure Alken Stainless Steel 12L ( RO + UV +UF + TDS + Alkaline ( Let's try it ) ) Model with an annual charge of around 2K. If anyone has used it.. Please write your experience. Thanks.

I will edit the Guide with Pictures later as I have been writing for over an hour now.:oops:.

Even I was furious when I found out about this practice a few years ago. But now I feel that time or usage based expiration is an overall much better option as people may not look after their water purifiers due to lack of time or expertise. Plastics degrade with time whether you use the filter or not. RO cartridges start to foul as they process more and more water. To ensure safe drinking water all the time, it's better to err on the side of caution and stop the water flow altogether.
na man, its just greed and regulatory failure. Ideally, you should take AMC and get it serviced by them. Filter only needs to be changed when it gets used up and waterflow slows down. We have had no issue in previous model for more than a decade. Water was always fine.

We have had it serviced maybe 5-6 times this year instead of around twice i think. Recent visit happened just in 2-2.5 months after last one. And water just stops instead of slowing down which is very inconvenient.
The guy who does the work, works for company that is contracted by Eureka Forbes. He has been servicing our water filters for more than a decade. He himself admitted that EF does this so that people who don't ask get billed for multiple unnecessary filter changes ( i think AMC covers 1 change). Filters should slow down once they choke which also depends on level of pollution in water, you don't just stop water flow at an arbitrary point.

Hello all,
I'm looking to buy a water purifier to replace a very old Kent RO system. What are your thoughts on Livpure brand? I like their purifiers (specifically, the Allura Premia) the most, followed by Blue Star and then Kent. Located in Navi Mumbai if that makes a difference. Preferably looking to move away from the Kent brand because of high maintenance costs (filter prices). Already have a pre-filter installed. Thanks.
 
@Stronk , buy local/generic brand water purifier, walk near by market and you will find at least 2-3 generic brand sellers, each & every branded water purifier need high maintenance cost (filter prices).

Generic brand seller too quote high but you can negotiate or buy directly from Az/FK the brand that have lots of spare options.

Will always prefer a local non branded one which I can maintain by myself. 4.5years since I last replaced membrane and filter in my current RO. only had to replace sediment filter in the external housing. still does its job, getting good quality water.

Anyone here using Urban company Native water purifier ?
Need honest review
I just bought the Urban Company native M2 couple days back for 17.5k. The water tastes damn near perfect for me. It's touch based dispensary, so far it works well and good, yet to see how reliable the touch after a few thousand litres.
It came with 2 year warranty with free service, free filter replacement, etc. Post that it's about 3.2k and the filters could last 1-2 years.
The only downside is it wastes a lot of water. 7lts wasted for every 3lts. I'm not sure if that's expected from all RO purifiers?
How's your experience using it ?
What is the output TDS and can you adjust it ? I have seen some reviews stating TDS below 50
How often does the pre filter needs cleaning or replacement ?

It's been perfect for my use case. We use an average of 4-5ltr per day and it's been 13 months since I bought it.
Output TDS shows from the filter sensor and not the tank so it was always inaccurate from what was shown in the application, but since the last update it shows approx TDS (ss attached)

TDS can be adjusted by yourself. You'll need to open the front housing and tighten/loosen the bolt for TDS.

My prefilter turned black in less than a year (4 different waters, borewell, tanker, BBMP and rainwater), they ordered a replacement and changed it for free. The filter health shown in the app is a gimmick, there's no sensor to detect it, the health simply degrades based on time and usage.
The service is top notch.

what is your source of water? Big City Corporation or Well?
 
Good deal on this right now if you don't require RO and are ready to live with a plastic tank. With an SBI CC, it should be under 7k.

Isn't tds below 50 low ?
They have also made changes to the new models launched in 2024, removed tds controller and uf

Do you think gravity will be enough for uv uf filter (pre filter - sediment - carbon - uv - uf). Thinking of attaching a 15L tank above the uf filter, maybe 0.5m higher to manually feed water without overhead tank.

Or better to use a low pressure pump and feed to filter directly without overhead tank.
