Voltas which sells the Aquaguard brand, sells R.O system for Rs.12,000. If you check out the Yellow pages for portable R.O.systems you can find something in Rs.10,000 range. Its not just the price, checkout the maintenance details from the supplier. If you are looking for the local brand I have described, I have to check with my family friend on the details, he has been using this system for about 2 years now.

Got a demo of the high end RO system from Eureka Forbes (7 stages, with UV treatment, costing Rs.25,000)…..the water from the system still had odour and was not tasteless…read-on.
Eureka Forbes sells 2 models with RO through dealers. One at Rs.7000, a pure RO plant and another at Rs.14,000 with 7 stages. Besides this Eureka Forbes do direct marketing of another system which has UV treatment, and some minor features at Rs.25000. Anyway wanted to try the highend system. The Sales person gave a good level of dump on TDS (Total Dissolved Solids) and mentioned that TDS should not be ridiculously low as in Saravana water etc. TDS measurements from our ground water was around 800, and post RO was around 50 to 100, whereas Saravana Water was between 10 to 20. The Sales person advised that TDS too low means the water is devoid of any minerals and advised to go with the high-end system. The Sales talk would not stop extolling EF prompt door-step service etc, when I interrupted with “Well TDS or no TDS, I don’t care, I want my water to be tasteless and odourless from the system, else I would directly take my well water which is clean, gets UV light from direct sun-light, and the water is potable with minerals”. After this I asked the Sales person to sample the Metro water out of his RO system, and he confided that the water was not odourless nor tasteless, and quickly added a new unit would perform better…..With a smile I mentioned, you are most welcome to do the demo again with a new system, and until then its good bye to Eureka Forbes RO. The point I am trying to make is, get yourself a demo, know the investment and running costs before you buy an RO system…

Yesterday Eureka Forbes Sales person came in for the second round. While the unit was running, I asked the Sales person for the justification of the Integra 7 at Rs.24,000 compared to their own brand selling an RO system at Vasanth for Rs.8,000 to Rs.14,000. Since it was their own brand, the Sales person came up with “I think” etc, and at that point I requested the sales person to come back to me with the facts straight with feature comparison of this product with their own models as well as with their competitors like Kent. Finally I also got to measure the TDS (Total Dissolved Solids) of the well water, RO rejected water and the RO water Vs Saravana Stores bottled water. The results are as follows,
TDS of my well water ~800
TDS of RO unit rejected water ~600*
RO water ~50
Saravana Stores ~20
*don’t ask me why TDS of RO unit rejected water is purer than the TDS of my well water. Perhaps the TDS gets stuck in the filters or in the RO membrane.
Also I got to talk to one Dr.Axxxx Kumar of Eureka Forbes labs to know their lab-results Vs competition. The summary was that their RO membrane is more or less identical vs competition. The Integra7 has optional modules not available in competitors such as for,
a. removal of heavy metals (Cadmium) & iron which may not be completely eliminated. Note this optional module may/may not be relevant, as it was launched for WB & Orissa.
b. Magnetizing chamber
In summary for high-end RO systems, Kent and Integra 7 stand-out in the category of filtration+RO+UV. Kent system costs around Rs.14,000 only, but does not have auto-clean of filters like Integra7 (I need to check this out). But personally I don’t mind manual cleaning than having to pay Rs.10,000 more on the Integra7. This ends my dilemma. Once again vanilla RO systems (with pre-filters) start at Rs.8K from Eureka Forbes.
Thanks to Sudarsan for sharing his experiences.

hi,
was jus running thru aquaguard ultra and Pureit – the price differential b/w the two is very high – is it b’coz of usage of electricity in pureit and replacement of batteries. Can u pl let me know what is the life of battery and what is the cost of replacement
actually vivek,
i am really glad that i have come across such an useful website and am referring this to many of my friends – ur site is very useful for us and pl do keep posting interesting ones
all the very best
@ Vinoth
Perhaps we were not clear in our post. Both Pureit and Ultra models do not use electricity at all.
The term battery in Pureit refers to the filter kit inside the purifier which needs to be replaced once 1500 litres of water has been dispensed.
As shown in the picture on the post, the indicator turns red to show that it needs to be changed, so you dont have to count the consumption in litres. As far as we recollect the replacement filter costs around 300 rupees.
The price difference is a big question for us too. Perhaps there are some factors which make aquaguard’s product more expensive.
We always wanted to create a valuable source of information for home owners in India as there is none at present.
We are also very happy to note that you find the posts interesting and of practical use.
Thank you for referring us to your friends. Hope they find it intersting too and do the same
I have hard borewell water in place now..In future i might get river water which is soft..I would like to go for RO purifier below 15k…Which 1 should i go for considering these..I have shortlisted whirlpool purafresh deluxe and kent grand..Im getting whirlphool @ 3k lesser than kent grand in a offer.which should i go for…please mail em the details to ganesh.pb@gmail.com
I get muncipality water at home with tds of abt 200 ppm.
Using a Kent RO system reduces the TDS to abt 50. Should i use a RO system or a UV system.??
Great information…
Well done…

With respect to buying a water purifier, it is pertinent to note that there is no single water purifier which offers a panacea to all types of water-borne contaminations.
What is vital is to understand the characteristics of the source water by opting for a complete laboratory analysis before choosing a purifier. It may sound a little superflous, but the fact is today’s ground water certainly needs to be thoroughly analyzed before opting for a purification system.
It is common knowledge that today’s air and soil are contaminated by diverse types of deadly contaminants – hitherto unknown – on account of the impact of unprecedented industrialization and other environment-unfriendly factors. These contaminants easily make their way to the water when the water passes through the atmosphere as rain. Subsequently, this water also picks up contaminants from the soil while percolating down the ground.
Major contaminants in today’s water include suspended solids, fine silt, dissolved iron, inorganic chemicals, heavy metals, volatile organic compounds, traces of industrial effluent chemicals and a wide range of deadly microorganisms (bacteria, virus etc).
In the event of government supplied water, probably our options can be narrowed down. But still, it is always advisable to take decisions on the basis of concrete information.
It is also to be noted that these factors have made water purification business a very lucrative one prompting all and sundry to jump in to the bandwagon. There are numerous (numbering into thousands) small timer / one man set ups selling substandard purifiers in the market. We are certain that our government will soon come out with some market mechanisms to control the mushrooming of these unorganized sector.
Nevertheless, the responsibility of safeguarding our family’s health primarily rests on us. Anybody who is planning to buy a water purifier needs to do the following :
i. Test your source water in an accredited / reputed laboratory on
physical, chemical and biological parameters (worth spending since it
is the question of our family’s health)
2. Identify a few good / reputed water treatment companies and forward your
analysis report to all of them (Apart from visible brands, online search can
also throw up adequate information)
3. You will get sufficiently enlightened once you listen to all of them
4. Check the credentials of these companies (technical expertise, track
record, service infrastructure, customer feed back )
5. Take an informed decision
If you still need more information on this subject, please feel free to mail me at sales@morfindia.com.
Wishing you and your family many years of HAPPY and HEALTH life.
Warm regards

confiscating of this my hard earned fund of which I quickly denounced myself as the beneficiary of the fund by filing in a
motion that the fund belongs to a foreign partner .My need for this business proposition and to acquire these properties is
very urgent as I am planning to move out of this country with my family down to your country.
