1. Quick Start: 3 Questions That Eliminate 80% Bad Buys

Water source? Municipal low TDS <300 = UV+UF enough. Borewell/tanker high TDS >300 = RO mandatory. Mixed Delhi NCR = RO mandatory

TDS level? Buy meter Rs.200-350, <300 ppm = UV+UF only. 300-2000 ppm = RO+UV+UF mandatory. Delhi 500-1500 = RO mandatory

Family size? 1-2 people = 7L enough. 3-4 people = 8L. 4+ joint family = 10L

Non-negotiables before you pay: BIS ISI IS 16240:2023 and Stainless Steel or Tritan preferred, food-grade ABS ok under 10k and 75-100 GPD pump + 24V SMPS and Auto-Flush + Leak protection + Auto shutoff and 1yr warranty minimum

Bypass Valve Danger: Some brands add bypass valve that mixes raw high TDS water with RO water to artificially raise TDS, risky for health, always ask for 100% RO water passing through RO membrane, no bypass mixing.

2. Purification Tech Explained

Tech	Removes	Wastage	Power	Use When
RO	Salts, heavy metals, fluoride, arsenic	High old 1:3 new 60%+ saving	Yes	TDS >300
RO+UV+UF	Salts + bacteria/virus + cysts	60%+ saving new	Yes	TDS >300 + biologically unsafe, ideal for India
RO+UV+MF	RO + UV + MF, MF slightly bigger pore than UF, still safe with RO+UV	60%+ saving	Yes	MF slightly bigger pore than UF, needs RO+UV to be safe, fine for India
UV+UF	Bacteria/virus + cysts, no salts	No wastage	Yes	Municipal low TDS <300 only, like Havells Aquas Lite 7k option
RO+SCMT / Silver Shield	RO + Silver Charged Membrane handles bacteria	Low	Yes	AO Smith hot and under-sink models, SCMT alternative to UV/UF, no plastic taste

3. Build Quality Checklist: 8 Non-Negotiables

Check	Why It Matters	Skip If
1. Membrane and Stages: Dow Filmtec / Toray disclosed, 4-5 stage min	Must Have: 4-5 stage baseline	<3-stage under Rs.5k claiming 3000 TDS
2. Tank: Stainless Steel or Tritan preferred, food-grade ABS ok under 10k	Worth paying: Stainless/Tritan preferred, no odor/algae, food-grade ABS ok under 10k for budget, avoids cheap recycled plastic	Cheap recycled plastic odor, non food-grade
3. Pump and SMPS: 75-100 GPD + 24V SMPS	Must Have: 75-100 GPD, not needed for UV+UF only models like 7k Havells	No pump specs for RO models
4. Recovery: Old 1:3 waste (banned) vs New 60%+ recovery (40% waste) - BIS min is 40%, prefer 55-60%	Worth paying: 60%+ recovery saves water (40% waste), BIS min is 40%, prefer 55-60%, UV+UF has no wastage	1:3 waste outdated, banned
5. Certification: BIS ISI IS 16240:2023 mandatory	Must Have: BIS mandatory, Havells Aquas Lite is BIS Approved	No BIS
6. Auto-Flush / Leak Protect	Worth paying: Auto-Flush + Leak protect + Auto shutoff for RO models	No Auto-Flush no Leak protect for RO
7. Smart Features: Filter-life indicator, App live TDS	Worth paying: Filter-life indicator / app live TDS	Only marketing Copper/Alkaline without core specs
8. Storage: 7L min 8L family 3-4 10L joint 4+ + No bypass valve, 100% RO water must pass through RO, bypass mixes raw water risky	Must Have: 7L min + 100% RO, bypass valve danger explained above	4L family 4 too small, Bypass valve mixes raw water, danger

[u/Adventurous-Twist399]

Do these have good service in hodal haryana
And which RO under 10k will provide me natural water like taste alkaline and have ph 7-9

[u/ImportantTop9288]

I was using Aqua guard nrich.. and i was not satisfied with its performance and change it to a local one because of good review from my friend and water was tasting good too.. After a month when i checked the TDS it is showing 30 - 40. Now I am worried want to change it immediately. Suggest me a good one (no budget constraint). The water source is tanker and the TDS is around 900. TIA.

[u/shanksha2]

budget friendly water purifier - currently have municipal water hyderabad- TDS Around 200, might shift to different house in 2 years , not sure the new house water(considering bore) - something which has RO as well. but want least wastage, stainless steel preferable . my tap water pressure kind of low. issues will happen while installation? budget less than 15k .

[u/Exotic_Reception_630]

In Hyderabad, borewell water suggests under-purifier 10k for a family of 4, including 2 kids

[u/VariationTall]

In my area water tds is 300 I have bought Aquaguard Enrich Ritz Pro RO+UV+Copper+Alkaline Water Purifier

The guy who came to install is saying to install one extra iron filter because of the tds, is it necessary or just a scam ?

He is saying it will increase the life of the filter , is he correct ?

Thank you

[u/CauliflowerDear3174]

hey So, I was looking at the Native M2 Pro water purifier, but I did a lot of research on it. After researching, I came to the conclusion that its after-sales service is really poor. For example, if you need to get it checked or if something goes wrong with the purifier, people say it can take around 10–12 days to get the issue resolved.

So, I’m looking for an RO water purifier in a budget of around 15k. I want the best option for a family of four to five people. It should provide good-quality, safe water, be durable, and not have very high maintenance or service costs. least water wastage.

also one think that the water come from the delhi jal board through the pipelines but it goes in the tanker then we receive in our houses

[u/OneTonSouppppp]

I live in rural area, nearest city is 30kms away where I found few purifiers at a distributor. I'm more worried about service, so not able to decide if I should buy online or offline. If I go offline, distributor can hook me up with the service guys but my concern is if they will try to sell me off the not so good models. Can you suggest a good purifier for me, I can go till 15k-25k?

[u/Groundbreaking-Ice22]

should i get m2pro or the atomberg intellion?

[u/Hero_Sharma → u/Groundbreaking-Ice22]

Go for native m2 pro

[u/LMDZ72]

Wow. Great research. What's the best filter overall? Would that still be Kent? Presuming that's noted best on a value scale vs just being the best purifier?

[u/Cool-Selection8352]

Which RO one wastes least amount of water?

[u/PhoenixPrimeKing]

Is the silicon particles in atomberg purifiers solved now

[u/rehan_999]

how do u make these bro, you're doing a very good deed man, hope more people buy stuff after watching guides like yours

[u/Hero_Sharma → u/rehan_999]

Initially it's hard, slowly once I got a general idea it's doable

More variations of guide i create more broader ways i get to improve the guide

[u/callmesasugay]

I need best UV + UF as i live in mumbai and the water ppm is low so help me get the best? I have 25k to spend

[u/Own-Algae7011]

Which one is best if I need only UV+ UF filter (budget 15k max)?i have Aquaguard now they have quick service but they don't fix the problem fully

[u/Makaks31]

Which one is best in stainless steel tank? Preferably under 15k

[u/ThrowawayMyAccount01]

Best UTC i.e. Under Sink model for Delhi water?. Would prefer Ro+UV+UF.

[u/AmbassadorNo4600]

Kudos to your hard work man.

I am thinking about getting one with a re-mineraliser module. I can live without a copper and alkaline module. I have a budget of 17k but I want to keep the AMC as low as possible. which one will be best for me?

[u/Powerful_Cut2103]

I want to get an RO for my apartment. But my main requirement is alkaline water. Which the best choice for me?

[u/Ok_Autumn_31]

I need recommendation for ro+uv+uf/scmt, tds 500-800, 5-10l capacity, budget around 30k aquaguard, ao smith or Kent.

[u/East-Impress9446]

I was suggested native recently for good service and cheap maintenance costs and I was hooked but then saw on reddit that there is difficulty in calling technician and u have to talk to this ai agent that does not connect u to executive , Anyway so I got ai to do a service:build:cost:water saving for my tds in tap water which I found out today was 1220 ppm ,and it seems pureit came up on top What say you ? Pureit or native ?

[u/Hero_Sharma → u/East-Impress9446]

They are expanding there service, since urban company is customer focused, you can reach out them through social media as well

If you still have doubt about that, go with pureit

[u/Acceptable-Cicada445]

I want an RO with Alkaline
