Choosing an air purifier in India requires understanding a set of parameters that differ from those relevant in other markets. Indian conditions include unique seasonal pollution patterns — particularly the October to January peak in North India — as well as year-round particulate challenges from traffic, construction and agricultural burning.
The most important specification is CADR (Clean Air Delivery Rate), expressed in cubic feet per minute (cfm) or cubic meters per hour (m³/h). To clean a room effectively, the purifier's CADR should be at least 2/3 of the room's square footage (in cfm) for a standard 8 ft ceiling height. For India's pollution conditions, sizing for 1× the room area is advisable.
Filtration stages matter as much as CADR. A complete purification system should include a pre-filter (for large dust and hair), True HEPA (for PM2.5, allergens and biological particles), and activated carbon (for gases, odors and VOCs). Advanced systems add a PHI or UV-C stage for pathogen inactivation.
The O₂Cure range is designed specifically for Indian indoor conditions, from compact residential units to high-capacity commercial systems. Each product uses the same underlying TriCure™ technology platform — ensuring consistent performance across the range.
Key specifications to check before purchase: HEPA grade (True HEPA, not 'HEPA-type'), CADR rating verified by an accredited third-party test, filter replacement cost and frequency, noise level at different fan speeds, and warranty terms.
