Find Your Purifier

The right purifier for your room, in about a minute

Most air purifier advice gets one thing backwards: it starts with the product, not your room. We do it the other way round. This quiz weighs three things that actually decide the answer — how big the room is, how dirty your city’s air tends to get, and what you are trying to fix at home.

Room size comes first. A 12×12 bedroom is 144 sq ft; an open living-dining is often three times that. A purifier sized for the smaller space will struggle in the larger one, running flat out and still falling behind. So we lean toward picking up, not down. If your room sits on the line between two models, we will nudge you to the bigger one — a slightly oversized purifier simply runs quieter and on a lower speed, while an undersized one never quite catches up on a bad day.

City air tier matters next. A winter evening in Gurugram is a different job from a calm week in coastal Chennai. We factor that in so your purifier is matched to your worst days, not your best. Finally, your concern — dust, pet dander, smoke, a baby’s room, or a dust allergy — shapes which features earn their keep.

No email wall, no pressure. Answer three questions and get one honest recommendation.

How we decide

We would rather show our working than hide it. Here is exactly how the recommendation is made.

  • We boost effective room size for severe-AQI cities. If you live somewhere with regularly punishing winter air — Delhi’s winter AQI, for instance, routinely crosses 300 — we treat your room as a little larger than its floor area. That gives you headroom to run a lower, quieter speed on bad days and still keep up.
  • We never recommend by price. The quiz does not know or care which model costs more. It matches your room and your concern to the right fit, full stop. If the smaller, less expensive purifier is genuinely right for your space, that is what you will see.
  • We are honest about limits. An air purifier helps the air inside one room; it does not fix the city outside, and it is not a medical device. For health concerns like asthma or allergies, please talk to your doctor as well.
