Water & Air Purifier Guides: Straight Answers
These guides exist because the most consequential purifier decisions are not about which brand to buy — they are about understanding your water and your air well enough to know what you actually need. Get that right and a ₹3,000 purchase can be the correct answer; get it wrong and ₹35,000 buys you the wrong machine.
We have tried to be genuinely useful rather than diplomatic. Where the popular answer is wrong — alkaline water's health claims, 'zero waste' RO, stage-count inflation — we say so, with reasoning you can check.
