How to Choose the Right Air Purifier for Allergies for Your Home in India
A step-by-step guide to selecting an air purifier based on room size, budget, and specific needs like allergies, pets, or smoke.
Step 1. Calculate the CADR you need for your room size
Measure your room’s floor area in square feet, multiply by ceiling height (use 10 ft as a default for Indian homes) to get room volume. Required CADR (cfm) = (ACH × room volume) / 60, where ACH is your desired air changes per hour (5 is typical). Convert cfm to m³/h by multiplying by 1.699.
Step 2. Set your budget tier
Decide which price bracket fits your needs: under ₹10,000 for basic HEPA coverage, ₹10,000–₹15,000 for stronger CADR and smart features, ₹15,000–₹20,000 for larger coverage and better filtration, or above ₹20,000 for premium multi-stage filtration and extended warranties.
Step 3. Match the purifier to your specific use case
Choose based on your household’s needs: HEPA + antimicrobial or copper filters for pet owners, Anti-Virus HEPA or H13-grade filters for allergy and asthma sufferers, high-CADR models with strong activated carbon for smoke and smog-heavy areas, and app-connected models with real-time AQI display if smart monitoring matters to you.
Step 4. Check filter replacement cost and warranty
Compare the long-term cost of ownership, not just the upfront price. Look at replacement filter cost, expected filter lifespan (6 months to 2 years depending on brand), and warranty length (1 to 8 years) before finalizing your choice.
Choosing from the best air purifiers for allergies in India: Coway AirMega Lineup Compared
AirMega AIM vs AirMega 150 vs AirMega 250 — Which One?
All three share Coway’s core filtration DNA, but they solve different problems:
- AirMega AIM is the quietest of the three (22 dB) and the only one with 360° auto-oscillating intake — best if you want one purifier to cover a whole small-to-medium room evenly rather than pointing in one direction.
- AirMega 150 trades the 360° intake for a patented Anti-Virus Green HEPA filter that actively kills viruses and allergens rather than just trapping them — the better pick if allergies or illness exposure are your main concern.
- AirMega 250 is built for space, not subtlety — 930 sq ft coverage and a 30-minute rapid-clean mode make it the only one of the three suited to open-plan living rooms or halls.
If you’re deciding between the AIM and the 150 specifically, this 1:1 spec comparison breaks down the differences side by side. For 150 vs 250, see this comparison.

How to Choose the Right Air Purifier
By Room Size — CADR Calculator
Match CADR to your room, not the other way around:
- Room volume (ft³) = floor area (sq ft) × 10 (using 10 ft ceiling height as the Indian default)
- Required CADR (cfm) = (ACH × room volume) / 60, where ACH (air changes per hour) is typically 5
- Convert cfm to m³/h: multiply by 1.699
Examples:
- 150 sq ft bedroom, 5 ACH → CADR ≈ (5 × 150 × 10) / 60 = 125 cfm ≈ 212 m³/h
- 300 sq ft hall, 5 ACH → CADR ≈ (5 × 300 × 10) / 60 = 250 cfm ≈ 425 m³/h
During smog weeks (AQI 300–400), add 20–60% headroom so your unit isn’t stuck running at max fan constantly.
