Delhi's air quality is a serious concern, especially during the winter months from October to January when particulate matter levels can reach hazardous concentrations. An effective air purifier is one of the most important tools for protecting indoor air quality during this period.
When choosing an air purifier for Delhi's pollution, the key parameters to consider are CADR (Clean Air Delivery Rate), HEPA filtration efficiency, activated carbon capacity for gaseous pollutants, and the size of the space to be covered.
PM2.5 — particles smaller than 2.5 microns — are the primary health concern during Delhi's pollution season. These particles penetrate deep into lung tissue and can cause serious respiratory and cardiovascular conditions with prolonged exposure.
A true HEPA filter captures 99.97% of particles at 0.3 microns. For Delhi's pollution conditions, a purifier should be sized for at least 2× the room's CADR requirement to account for high pollutant loads during peak season.
The O₂Cure range includes models designed specifically for Indian indoor conditions — from residential units for bedrooms and living rooms to commercial-grade systems for larger office spaces and healthcare facilities.
