Do You Need an Air Purifier at Home? A Practical Guide

Indoor air can carry dust, pollen, pet dander and smoke particles — especially in winter in many Indian cities. An air purifier helps you breathe easy and live clean.

How a HEPA purifier works

A fan pulls room air through a pre-filter for large dust, a true HEPA filter that captures fine particles, and often an activated carbon layer for odours. Clean air is pushed back into the room.

Size it to your room

Check the clean air delivery rate (CADR) and the recommended room area. A purifier rated for a slightly larger room than yours cleans the air faster.
