Do You Really Need an Air Purifier?
If you live in a city with poor AQI, have dust/pollen allergies, pets, or live near traffic/construction, an air purifier can make a clear difference in breathing comfort, allergies and sleep quality.
1. Filter Types – The Heart of an Air Purifier
The most important part of any air purifier is its filter system. Most good models use:
- HEPA filter (main filter)
- Pre-filter (for big dust / hair)
- Carbon filter (for smells & gases)
HEPA Filters – What to Look For
Look for True HEPA, HEPA 13 or HEPA 14. These can capture particles as small as 0.3 microns with over 99.95% efficiency, including:
- Fine dust & PM2.5
- Pollen
- Pet hair & dander
- Most airborne allergens
Avoid: Purifiers with only HEPA 11 or HEPA 12 – they are not enough for heavily polluted cities.
Pre-Filters – Extending Filter Life
Pre-filters catch bigger particles (hair, coarse dust) so the main HEPA filter lasts longer.
- Brands like Sharp, Coway, Honeywell, Philips often give washable pre-filters.
- Others use non-washable pre-filters that you can vacuum clean.
Carbon Filters – For Smell & Gas
Carbon filters help with:
- Cooking smells
- Smoke odours
- Agarbatti & fragrances
- Paint fumes & VOCs
UV, Ionizers & Other Add-ons
Some purifiers also offer:
- UV LED – to inactivate bacteria (as per brand claims).
- Ionizers – negative ions to speed up purification.
These are nice-to-have, not essential. A strong HEPA + carbon combo already does most of the job.
2. Filter Replacement – Life, Cost & Availability
Filters need regular replacement. Always look at the yearly cost, not just the machine price.
- Filter life (hours / years)
- Replacement filter cost
- How easily filters are available online / via service
Typical Filter Life (From Compared Models)
| Brands / Models | Approx. Filter Life | Usage Example |
|---|---|---|
| Honeywell, Mi, Dyson (except Big & Quiet), Carter, Philips | ~3,000 hours | ≈ 1 year @ 8 hours/day |
| Coway, Sharp, Qubo, Agaro, Cuckoo | 8,500 – 9,000 hours | ≈ 3 years @ 8 hours/day |
| Dyson Big + Quiet | Up to 5 years | Very long life, higher upfront cost |
For most brands, yearly filter cost is ~₹2,000 – ₹3,000. Dyson filters are higher, but with premium build & support.
3. Room Size, Coverage & Clean Air Delivery Rate (CADR)
How to Choose Coverage for Your Room
Brands usually mention room area (sq ft). To choose:
- Measure room length × width (in feet).
- Multiply to get the area.
- Add at least 20% as safety margin.
Easy guideline:
- Bedrooms / study: up to 400 sq ft
- Living + dining: 400 – 800 sq ft
- Full house / very large spaces: 800+ sq ft
Too small purifier: will clean slowly and struggle in high pollution.
Slightly bigger purifier: cleans faster – good if budget allows.
Slightly bigger purifier: cleans faster – good if budget allows.
CADR – How Fast the Air Gets Clean
CADR (Clean Air Delivery Rate) tells you how quickly the purifier can clean air in a given room. Higher CADR = faster cleaning.
- Some brands (like Dyson) don’t always publish CADR, which makes direct comparison harder.
- For large rooms, ensure CADR is also high, not just “coverage” on paper.
- Using a “bigger-room” purifier in a smaller room gives faster results.
Bonus Features – Nice to Have, Not Must Have
These can be useful but should be secondary after filter + coverage:
- Mosquito-catching (Sharp): chemical-free mosquito trap – handy if mosquitoes are a big issue.
- Bladeless fan (Dyson): great airflow; note it does not cool the room like an AC.
- Heating (some Dyson models): can double as a heater (often needs 16A socket).
- Wearable / portable purifiers: many use ionizers and can release ozone – effect is mixed; easy to skip.
- AC HEPA add-on filters: remove ~90% PM2.5. Not as strong as dedicated HEPA 13/14 purifiers, but a good budget upgrade.
Convenience Features
- Touch controls, remote control
- App connectivity (Philips, Dyson, Qubo, some Honeywell)
- Real-time AQI display (number or colour ring)
- Night mode, child lock, filter replacement alerts
