Indoor air can be up to 10-times more polluted than outdoor air. Many types of pollutants can affect indoor air quality. While some of these pollutants such as dust and hair are visible to the naked eye, most others go undetected. These invisible air pollutants can cause severe health issues including respiratory ailments. Home, office, and commercial air purifier products with multi-stage filtration process can be used to effectively remove pollutants from the air. Honeywell offers a wide range of air purifiers, designed and developed specifically for Indian consumers.
