Best Air Purifiers For Your Home
Do they work, how to choose the best air purifier for your house and mistakes to avoid
This month is not the first time, Indians, especially living in the capital have been complaining about the air quality. When New Delhi's skies hit "severe" on the Air Quality Index recently, citizens were compelled to march demanding better air quality so they could breathe again.
With smog, road and new realty sprouting everywhere constantly, crop-burning, vehicle emissions and many meteorological factors conspiring to blight our air, the need to make your home an oasis of clean air is no longer a question of affording luxury but necessity.
The smog has become a full-body experience: you can see it, smell it, and feel it sitting heavy in your chest. AQI levels are well past the “hazardous” mark, and even the most die-hard “open-window” loyalists have started Googling best air purifiers for 2BHK homes.
While DIY box-fan with a filter setup that's trending on Instagram may seem like a cheap fix for the problem and look totally creative, it is hardly the full answer to the issue.
Do Air Purifiers Really Work?
Before making a purchase it is worth asking the question do air purifiers actually work, or are they just another expensive placebo with good branding? The short answer: they do work if you buy the right kind and use it properly.
A decent purifier with a True HEPA filter can remove around almost 99 percentage of fine particulate matter (PM2.5) from the air inside your home. That’s the stuff that causes itchy eyes, sore throats, and coughing fits. Add an activated carbon filter, and you’ll also cut down on odours, smoke, and volatile organic compounds.
Even the best indoor purifier won’t fix outdoor air or structural building ventilation issues but it will help make your indoor environment healthier if you avoid placing it behind the furniture in your house, maximise its usage by keeping the doors and windows of the house shut while its on for minimum pollution and maximum output.

How to Choose the Right Air Purifier for You
One of the common misconceptions around getting an air purifier is that any size works well for the house, but here’s what to look for to make sure you pick a machine that actually improves your indoor air:
1. Match it to Your Room Size and Air-Quality Challenge
Think of it like investing a pair of thermal wears, you don't want to go for a 1-5 degree Celsius thermals for a trip to the Alps, they'd mostly be ineffective in a subzero temperatures. Similarly, when investing in an air purifier measure your room (length × width × height) and know how polluted your location is. In highly polluted cities like Delhi, experts recommend aiming for 4–6 Air Changes per Hour (ACH). What does that mean? The purifier should refresh the room’s air 4-6 times every hour.
Then check the machine’s Clean Air Delivery Rate (CADR), what it does is this tells you how quickly it can clean the air. Higher CADR means higher faster cleaning. And always follow the rule of thumb, for instance, for a typical bedroom (~150 sq ft), look for a CADR of ~250 m³/h or higher in a polluted environment.
2. Filter Quality Is Non-Negotiable
The core of the purifier is its filter. You want a True HEPA (H13/H14 grade) and not a “HEPA-type” or “HEPA-like” marketing gimmick. These filters capture particles down to ~0.3 microns with ~99.97 per cent efficiency. Because in India’s polluted air you also face gases, odours and smoke, make sure there’s an activated carbon filter as well.
3. Energy, Noise, Maintenance
Since you’ll likely run the purifier for long hours, it is essential that you check its noise level: for bedrooms ideally < 50 dB on high speed, and much lower in sleep mode.
Moreover factor in filter replacement cost and availability—filters need regular replacement in high pollution zones; if replacements are expensive or hard to get, the whole benefit drops. Ensure the brand has good after-sales support in your city—warranty, service centres, parts.
4. Placement And Usage Matter
How you use the machine is just as important as what you buy. So, place the unit where airflow isn’t blocked and is away from walls, furniture, bed-head and doors/windows if possible. Ideally, keep windows/doors closed while it runs to avoid continuous new pollution coming in. If you have a large living area, either get a higher-capacity unit or consider two units (one for main space, one for bedroom).
5. Smart Features
Things like air-quality sensors, auto mode, app connectivity or real-time displays are nice to have. But they don’t replace good core performance. Prioritise CADR, filter grade and room match over fancy extras. If budget is tight, focus first on the basics.
