Quick answer: To choose a domestic RO water purifier in Pune, check your water source and TDS first. Then match the storage to your family size: 10 L for 1–2 people, 12 L for 3–4, and 14 L for 5 or more. Buy from a local dealer who tests your water and installs it. Installation takes 45–90 minutes and needs wall space near the sink, a power socket, the inlet line and a drain. A1Aqua's purifiers cost ₹6,000–13,500 with installation included.
A home RO purifier is a five-to-seven-year purchase that you use every day, yet most families choose one in ten minutes from a showroom or a shopping app. This guide walks through the choice the way our technicians do on a home visit: water first, then family size, then features. It also covers what a good dealer should give you and exactly what happens when the purifier is installed.
Five steps to choose the right domestic RO purifier
- Find your water source. Is it PMC or PCMC municipal supply, borewell, tanker water or a mix? Your society office will know.
- Measure the TDS. Use a handheld TDS meter or ask for our free home test. Under about 200 mg/L, UV/UF protection matters most. Above 500 mg/L, you need a strong RO.
- Count the people and the use. Drinking only, or drinking and cooking? Cooking with RO water roughly doubles daily use.
- Choose the stages your water needs, not the longest list on the box.
- Check the after-sales service. Who changes the filters, how fast, and where are the spares kept?

Purifier size by family
Storage matters more than the flow-rate claims on the box. A bigger tank means water is ready when the power or the society supply is off.
| Household | Daily RO water (drinking + cooking) | Storage to look for | Our models |
|---|---|---|---|
| 1–2 people, flat or PG room | 8–15 L | 10 L | Zuric Black or White (₹7,000–8,500) |
| 3–4 people | 15–30 L | 12 L | Aqua+ (₹6,000) or Aqua Classic (₹6,500) |
| 5 or more, or frequent guests | 30 L + | 14 L | Purosis (₹10,500–13,500) |
| Home on borewell or tanker water | Any | 12–14 L, strong RO | Aqua Classic or Purosis |
All prices include standard installation. Full specifications are on our domestic RO water purifiers page.
Features worth paying for, and ones you can skip
| Feature | Worth it when | Skip it when |
|---|---|---|
| TDS controller | Municipal water with low TDS, to keep the taste and minerals | Very high TDS water, where it must be set carefully |
| UV lamp | Water is stored in building tanks, as in most Pune societies | Rarely worth skipping |
| UF membrane | Frequent power cuts, since UF works without electricity | You already have UV and steady power |
| Alkaline / mineral stage | RO water from borewell or tanker sources tastes flat to you | You are on low-TDS municipal water |
| LED display, premium body | You want the look and the indicators | Purely for water quality, as it does not change the water |
What a good water purifier dealer in Pune should offer
- A water test before the sale, at your home or with a sample you bring in.
- Installation by their own technicians, included in the price and not booked through a third party.
- A written warranty, with clear terms for electrical parts and the housing.
- Local spares and filters, so a service visit doesn't wait for a courier.
- A store you can walk into. Ours is at Shop No 11, Bhumkar Nagar, near Golden Care Hospital, Hinjewadi–Wakad Road, Wakad, open Monday to Saturday, 9 am to 6 pm.
- An honest answer when a simpler, cheaper purifier is enough for your water.
What happens on water purifier installation day
Keep ready wall space near the sink (away from the gas stove and direct sunlight), a 230 V socket within reach, access to the kitchen inlet line and a drain or sink outlet. Then the technician:
- Checks the site: inlet pressure, the wall surface and the drain position.
- Mounts the purifier on the wall, or under the sink if you prefer.
- Connects the inlet with a T-connector and a shut-off valve, so you can stop the supply during service.
- Routes the reject line to the drain, or to a container if you want to reuse the water for mopping or plants.
- Flushes the new filters and discards the first tank of water.
- Measures input and output TDS and sets the TDS controller for your water.
- Shows you the indicators, how to close the inlet valve and when the first service is due.
The whole job usually takes 45–90 minutes. If your flat is on a top floor fed by an overhead tank and the pressure is very low, tell us when you book, so the technician brings what is needed. Already bought a purifier elsewhere? Our RO installation service covers all brands.
Five common buying mistakes
- Buying RO for low-TDS municipal water without a TDS controller, so the water tastes flat.
- Buying a small tank for a big family, so the water runs out during power cuts.
- Paying for stages your water doesn't need.
- Ignoring the running cost. Filters every 6–12 months and a membrane every 12–24 months. See our RO service guide.
- Choosing a brand with no technician nearby.
