Buying guide
Understand the specs before you buy.
A purifier is only good if CADR, filter type and room coverage match your actual use case.
What is CADR?
CADR measures how much clean air a purifier can deliver per minute. It is the best starting point for matching a purifier to room size.
What is HEPA?
HEPA filters capture fine particles like PM2.5, dust and pollen. For Indian cities, True HEPA H13 is a strong baseline.
H13 vs H14
H14 captures slightly more fine particles, but H13 is usually enough for homes when CADR and placement are right.
Activated Carbon
Carbon helps with odours, gases and smoke. It is especially useful during winter smog or indoor smoking exposure.
Room Coverage
Coverage claims vary. Always compare CADR against your actual room size and desired air changes per hour.
Power Consumption
Most modern purifiers use less power than an air conditioner. Higher fan speed uses more electricity and noise.
Filter Replacement
Plan for filter changes every 8-12 months, sooner in dusty cities or pet-heavy homes.
Maintenance Cost
The true cost includes filter availability, replacement price, electricity, and whether the pre-filter is washable.

FAQ
Air purifier questions, answered.
Straight answers for sizing, HEPA filters, electricity, filter replacement and India-specific pollution.
What size air purifier do I need?
Start with room area, ceiling height and target ACH. Larger rooms and high AQI need higher CADR. Use the AQIRadar calculator for a room-specific estimate.
Is HEPA H13 enough?
Yes, H13 is enough for most Indian homes when paired with suitable CADR. H14 is useful for highly sensitive users or medical-grade environments.
Can one purifier clean an entire house?
Usually no. A purifier works best in a closed room. For whole-home cleaning, use multiple purifiers in bedrooms and living areas.
How often should filters be replaced?
Most filters last 8-12 months. Replace sooner in winter pollution, construction dust, pet-heavy homes or smoking environments.
Are air purifiers worth buying in India?
They are worth considering in high-AQI cities, for bedrooms, for children, and for people with allergies, asthma or long indoor exposure.
How much electricity do they consume?
Many purifiers consume roughly 25-60 W depending on fan speed. Running on auto or medium mode usually balances cleaning, noise and electricity.
