RO + Ionizer. One machine.
I'm-Possible. Built in RO.
2 → 1
Two machines. Two pipes. Two maintenance schedules. Now, one.
Every Indian home with hard water runs the same equation: an RO for safety, then an ionizer for health. Two machines. Two installations. Two service cycles. Two points of failure. Udaka eliminates the equation entirely.1
-800 mV
Negative ORP
From 3,000 TDS borewell water to -800 mV in one pass.
1,500 PPB
Molecular Hydrogen
Purified, restructured, and hydrogenated. One machine.
Up to 3,000
TDS
The widest input range in the SOMAWA family.
The Frustration
An RO under the sink. An ionizer on the counter. Different brands. Different service schedules. Different points of failure. One breaks, the other becomes useless. This is how most Indian homes with hard water live today.
You did not want two machines. You wanted one outcome — clean, healthy, restructured water. Udaka starts from that outcome and works backward.
"The best engineering does not add complexity. It removes it."
Consolidation
Udaka does not bolt two systems together. It integrates them. Water enters at up to 3,000 TDS. The built-in RO stage removes contaminants. The ionization stage restructures what remains. One input pipe. One output tap. One machine to maintain.2
7-litre integrated storage. 75 litres per hour flow rate. The entire process — purification to ionization — happens inside a single unit that fits where your old RO used to sit.
Illustration for representational purposes. Actual internal architecture may differ.
Hydrogen
Udaka doesn't just purify. It restructures — unlocking 1,500 PPB of molecular hydrogen from the water itself. The same molecule found in the world's most revered natural springs, now produced from water your RO stage already purified.3
Eight glasses a day. 30,000 glasses a year. 7.5 lakh glasses over the life of this machine. Every single one hydrogenated.
Why Hydrogen
0.27 nanometres. Crosses the blood-brain barrier where Vitamin C and E cannot. Selective — targets only harmful radicals, leaves beneficial ones untouched.4
1,300+ peer-reviewed studies. Zero known side effects. FDA classifies hydrogen gas as GRAS.
pH
Selectable pH from 5.5 to 10.5. Udaka handles the entire journey — from 3,000 TDS borewell water to pH-adjusted, hydrogen-rich, restructured water.
Neutral pH for medications and infant formula. When precision matters, Udaka gives you water that does not interfere — clean, balanced, exactly 7.5.
Engineering
The ionization stage inside Udaka is not a scaled-down version of anything. Five platinum-titanium plates fused in a vacuum furnace at 1,200°C — atomic-level bonding. The same AFS self-cleaning technology, the same IONIQ calibration as the standalone Amara. The RO stage purifies. The ionizer restructures. Built for a million glasses.

Three times the platinum. Engineered for India's toughest water conditions.
7 L
Integrated Storage
Purified and ionized. Ready when you are.
25 yr
Operational Standard
Built to outlast two decades of daily use.
"Built for the water India actually has. Not the water marketing pretends it has."

850 TDS borewell. One machine fixed it.
I had been foloowing this technology sinse the last 4-5 years and till date I have seen numerous demos but there wasn't any machine that single handedly take care of every water need unlike Somawa, we have there udaka model installed and that single machine can do the work of an RO and pressure tank and most imp Alkaline Ionizer.
No more two-machine headache
Best decision we made. Period.
Tanker water at 1200 TDS and this handles it
The best thing I like about this machine is the automatic TDS Controller, because in my home I get water TDS ranging from 300 to 730, and I was fed up by calling the technician every time but now it is not the case
Machine is solid. Bigger than I expected though.
The machine is bigger than what I expected and at the time of installation it made abit of a problem, but the services are no doubt very good
Pressure cooker time went down
Whenever I had to make rajma rice the cooker used to take approx 12-13 whistles to make the rajma but now since the time I have been making it in 9.5 poH water it takes up only about 7-8 whistles
Our old purifier broke 6 times in 3 years. This one, zero.
I have 2400 TDS at my place and I live in jodhpur, till now all the RO's that I have gotten installed in the past used to breakdown in 3-4 months at max and the membrane used to be changed and it was costing me heafty but in Somawa one benefit that I have is that their amc covers the mulktiple filter change as well at no extra cost
Delivery to Ranchi took almost 3 weeks
I got this machine installed in varanasi and the only problem I faced was that it took 2 weeks for the machine to get installed, but after since I hgave not faced any sort issues
Bought for parents in Varanasi
I bought this machine for my parents in varanasi two months ago and we have been using this since the last 8 months and I am shocked to see that my father used to take a medicine named ecosprin and he has stopped taking that in just a span of 2 months
Finally one machine under the sink
There is only one problem that we faced and it was that the standard modulare kitchen cabinet is made of 12 inches depth and the machine is 12.8 inches so we had to make some modifications later on but you can make this change before only, otherwise the machine and the people are very good
Sabzi wash setting was unexpected
Mai iss machine ke paani se daily phal sabzi ko doti hu aur mai daily dekhti hu ki jitna bhi paani hota hai voh ek dum green colour kaa ho jata hai, aur mohit ji jo service karne aate hai unka kaam bhi bohot acha hai
The self-cleaning sound scared the dog
I had worked with some foreign brands as well but after 1-2 years the people who I recommended it to came back with after sales problem and I still remember that 3 of my clients litrally came and gave me the machine and I have been associated with Somawa since almost 2 years now and i have some users whose friends and family have gotten like 4-5 machines
Looked at everything available in India
We reached on this technology for about 4 months and after that we got Udaka installed
Family of 6, tank lasts the day
We have a family of 6 members and we have seen the health benefits and ghar mai bhi sabhi ko yeh machine acha lagta hai
Chapati dough is softer now
One day randomly I was trying to make bread and used alkaline water and my dough overflowed the container it was kept, and this happened for the first time
Manual could be better
When I saw the demo I had a lot of doubts and was planning to drop the technology but it was abhishek who litrally was on a call with me for I guess 1 hour and 34 minutes and at the end of the call I booked the product
Vizag borewell, 900 TDS, sorted
Since the day I have started using this water for alcohol, I have never had a day with hangover no matter how much the amount is or what ever the occasion is
Guests keep asking about it
The product speaks for itself I have never talked about this technology to my friends or anyone in the family they just saw and drank the water and today I know 3 people who have gotten this machine installed
Quieter than our old purifier
We have seen a lot of health benefits and one of the major benefit we have seen is in acidity, I highly recommend this to everyone
Wish there was a filter life indicator on the outside
The service is good, the technician comes in 4-5 hours itself
My brother thinks I overpaid
I have gotten this machine after fighting with my whole family, but I know the technology and have used this for a long time in the past and this tehnology does work, the main reason to shift made in india machine is the after sales service
Summer peak TDS and it didn't skip a beat
I have 590 TDS at my home and this works very good, I have no problem with it and ved ji does very good service
5.5 beauty water is my morning routine now
I have stopped using makeup remover and I only use 5.5 ph water now, and I have seen drastic changes in my skin
Water is fine but I expected to feel more different
I know the benefits of alkaline water and I even recommened to everyone who is reading this comment to get this machine installed
Deepak handled a tricky installation perfectly
It took 3 hours for himanshu to get this machine installed but I thing that I have to mention is that no matter how long it took he did all the perfect work, I could point one thing that is off
Worth it
The installation was done very cleanly by Mohit ji and he is very corporative
FAQ
1 Based on the common Indian household setup where TDS exceeds 200 ppm, requiring separate RO purification before ionization can be effective.
2 Udaka integrates RO membrane purification and platinum-electrode electrolysis in a single housing. Input water up to 3,000 TDS is first purified, then ionized in sequence.
3 Natural hydrogen-rich springs typically contain 0.2-0.8 PPB dissolved hydrogen. SOMAWA Udaka produces up to 1,500 PPB.
4 Ohsawa, I. et al. Nature Medicine 13, 688-694 (2007). FDA classifies hydrogen gas as GRAS.
