India, Jan. 12 -- We keep buying air purifiers like they are bedside gadgets, then expect them to fix a full living room. That is where most homes actually spend time, where dust settles, cooking smells linger, and outside smoke sneaks in through small gaps. So for this story, we are sticking to one simple rule that air purifiers for a large room should clean the whole space, not just the air right next to the unit.

This is why we have shortlisted models that claim big coverage, back it with real filtration like HEPA and carbon, and add useful cues like PM readings or auto modes. If you are comparing Honeywell, Coway, Winix, Shark, Biome, and Levoit, these picks should help you choose with fewer regrets.
