How to Choose Your Perfect HEPA Purifier
Match CADR to Room Size
- Bedrooms (~150–250 sq ft): CADR 200–300 m³/h.

Check the Filter Stack
- True HEPA (H13): Essential for PM2.5 & allergens.
- Activated Carbon: Required for odours and VOCs.
Consider Noise & Sleep
- Look for ≤25 dB night modes for kids/elderly.
- Check noise levels at medium speeds, not just the lowest.
Service & Filter Costs
- Check local filter availability and costs.
- Plan for annual replacement, or every 6-9 months in polluted cities.

Ar. Sourabh's Pick: Which Purifier is for You?
Your choice depends on room size, noise tolerance, and budget. Here are our top recommendations for different Indian household scenarios.
Small Bedroom (Budget)
Xiaomi Smart Air Purifier 4 Compact
Perfect for kids' rooms or light sleepers. Its 20dB sleep mode is exceptionally quiet, and the app control adds convenience without a high cost.
Family Workhorse (VFM)
The best balance of performance, reliability, and low running cost. Its long-life filter makes it a dependable choice for master bedrooms.
Open Living (Premium)
For large, open-plan living areas where aesthetics and quiet performance matter. It purifies a large space effectively while doubling as a bladeless fan.
Maintenance & Safety Guide
Quick Safety Tips
Maintenance Routine
Common Mistakes to Avoid
- Buying low CADR for a big room: This forces the unit to run on max speed, creating noise without effectively cleaning the air.
- Placing it behind furniture: Obstructing airflow drastically reduces performance.
- Running with windows wide open: You're trying to purify the whole neighborhood. Keep windows closed during operation.
- Skipping filter changes: A clogged filter doesn't purify; it just circulates dirty air.
- Using fragrances nearby: Aerosols and incense can skew sensor readings, causing the purifier to ramp up unnecessarily.
- Ignoring noise specs for bedrooms: A loud purifier will disrupt sleep, defeating one of its main purposes.
Colours & Materials
Matte white or grey finishes blend into most Indian interiors seamlessly. Black glass fronts can complement modern wood and metal themes. For compact rooms, purifiers with rounded edges feel less intrusive. Taller, tower-style designs like Dyson's often work well with vertical furniture lines in living rooms, creating a cohesive look.
Elder-Friendly & Accessible Solutions
For elders, prioritize purifiers with large, legible AQI displays and simple physical buttons over touch-only controls. Models with a quiet night mode (≤25 dB) are crucial for undisturbed sleep. Using the auto mode is often best, but for those with sinus issues, running the unit at a medium speed in the evenings can help clear allergens before bedtime.
Small Details for Architects & Designers
Power Point
Plan a 10A, 230V socket with ≥30 cm clearance around the unit's intake and outlet.
Air Pathing
Avoid obstructions. Align the outlet towards the room's center for optimal circulation.
Multiple Units
For >450 sq ft or L-shaped rooms, spec two smaller units instead of one oversized one.
Filter Logistics
Place units where filters can be easily swapped without moving heavy furniture.
Designer’s Perspective: Trade-Offs & Thresholds
Key Thresholds
- Bedrooms: CADR ≥ 250 m³/h
- Living Rooms: CADR ≥ 350 m³/h
- Night Mode: Noise ≤ 25 dB
The Main Trade-Off
Premium models offer quieter operation, smarter features, and larger coverage, but at the cost of more expensive replacement filters. Value models save money upfront but may need to run at higher, noisier speeds during heavy pollution spikes to achieve the same result.
Frequently Asked Questions
Do I really need HEPA H13?
Yes. For Indian conditions, H13 is the standard to aim for as it captures fine PM2.5 and allergens far more effectively than older "HEPA-type" filters. Always pair it with an activated carbon layer for odors and gases.
What CADR do I need for a 12x12 ft bedroom?
A 144 sq ft room requires a CADR of at least 200–250 m³/h to achieve 4-5 air changes per hour, which is ideal for allergy sufferers.
Can I keep windows open with an air purifier?
During periods of high outdoor pollution, you should keep windows and doors closed for the purifier to be effective. It's best to ventilate the room for a short period when outdoor air quality is better, and then run the purifier.
How often should I change the filters in India?
While most brands suggest 9-12 months, in high-pollution cities like Delhi or Mumbai, you should expect to change them every 6-9 months for optimal performance. Trust the filter replacement indicator on your device or app.
Are premium brands like Dyson or Blueair worth it?
If you need to purify a large, open-plan space or are very sensitive to noise, then yes. Their superior engineering often results in a better noise-to-performance ratio and more accurate sensors. For a standard bedroom, value picks are usually sufficient.
Is Coway still the most reliable brand?
Coway, particularly the AirMega 150 model, has built a strong reputation for long-term reliability and low-maintenance operation, primarily due to its exceptionally long filter life. It remains a top "set-it-and-forget-it" choice.
Do I need smart/app features?
App features are a great convenience for setting schedules, monitoring air quality remotely, and getting filter replacement alerts. However, they are not mandatory for effective filtration. A good auto mode can serve a similar purpose.
Where is the best place to put an air purifier?
Place it in the area where you spend the most time, like near your bed or sofa. Ensure there's at least 30-45cm of clear space on all sides for air intake and outlet. Avoid corners and placing it directly under curtains.
Do air purifiers really remove viruses?
H13 HEPA filters are capable of capturing airborne aerosols that may carry viruses. While they can reduce the concentration of these particles in the air, they are part of a broader strategy and not a standalone solution. Regular filter maintenance is key.
What about Philips service in India?
Philips (now Versuni) has one of the more widespread service networks in major Indian cities, which can be an advantage for warranty claims and support. It's always a good practice to verify serviceability for your specific pincode before purchasing.
