Buying for an office, society or factory? Get a system sized against your water report.
Water purifiers

Hot water on tap, and the best water recovery in the category
The default recommendation for Indian borewell water
Stainless-steel tank and self-sterilising UV care
Aquaguard's best-selling all-rounder, now with active copper
AO Smith engineering without the hot-water premium

Three calculators that do the thinking most purifier salespeople would rather you skipped.
Enter your TDS and water source. Get the correct technology and a realistic budget — including when RO is unnecessary.
Open calculator →Enter your room dimensions and local AQI. Get the minimum CADR you need, adjusted for real Indian conditions.
Open calculator →For facility and procurement teams: plant sizing, capex band, five-year TCO and a CapEx-vs-OpEx comparison.
Open calculator →Air purifiers
Ranked on CADR per rupee, genuine H13 HEPA filtration, filter availability and noise — because a purifier too loud to sleep beside protects you for zero hours.
Philips
Most homes in most Indian cities — the default answer if you want one purifier that just works.

Coway
Bedrooms, allergy and asthma sufferers, and small rooms where floor space is unavailable.
View details
Dyson
Buyers who want the best sensing and a design object, in homes with VOC or formaldehyde concerns from new furniture.
View details
Xiaomi
First air purifier, second bedrooms, and anyone who wants maximum performance per rupee.
View detailsTrimmers & shavers
Ranked on blade metallurgy, length precision and five-year running cost — because a ₹949 self-sharpening Philips costs less to own than a ₹549 trimmer replaced twice.
Braun
Daily shavers with dense or coarse beards and sensitive skin, who will keep the machine for five-plus years.
View details
Panasonic
Enthusiasts with exceptionally dense beards who want the best shave available and accept the support risk.
View details
Philips
Stubble and short-beard wearers, sensitive skin, and anyone who wants one machine instead of a trimmer plus a razor.
View details
Panasonic
Thick, coarse, fast-growing beards — the specification that beats Braun on raw cutting speed.
View detailsRefrigerators
Ranked on usable litres rather than the gross figure on the sticker, and on declared electricity units rather than the star count — because a 260 L fridge holds about 195 L, and a 5-star from an older BEE label is a 3-star today.
LG
Families of three or four who want the category's safest all-round choice

LG
Families of four who shop weekly and keep finding their current fridge full

Samsung
Families who store aromatic food and want the longest compressor warranty on the market

Joint families of five or six who want maximum capacity without moving to side-by-side
View detailsAir conditioners
Ranked on ISEER and declared units rather than the star count alone, on tonnage matched to real Indian rooms, and on the installation and service reach that decides whether an AC works in May.
Blue Star
A main bedroom or living room run for long nights through summer

Blue Star
Families who want to cap how much electricity the AC can use in a month
View details
Blue Star
Halls and living rooms of 200-230 sq ft run for long hours

Official launch prices and full specifications, verified from each brand's own India pages — with best-phone lists by price, camera, battery and 5G.
Shop by need
Because the best purifier for 1,400 ppm Jaipur borewell water has almost nothing in common with the best one for Kochi's soft municipal supply.
Commercial & industrial
From 100 LPH office units to 4,000+ LPH industrial RO plants — custom-engineered against your feed-water analysis to lower operating cost and handle high TDS.
| Capacity | Ideal for | Indicative capex |
|---|---|---|
| 100 LPH | Offices, cafes, schools, small hotels, 60-120 people | ₹75,000 - ₹1.5 lakh |
| 500 LPH | Factories, hospitals, large complexes, societies of 60-150 flats | ₹3 lakh - ₹6 lakh |
| 1000 LPH | Manufacturing plants, large hospitals, campuses, packaged-water units | ₹6 lakh - ₹12 lakh |

Local guidance
Every city page uses that city's actual water source, TDS band, hardness and AQI profile to produce a different recommendation — because the water genuinely is different.
