Data from the World Health Organization (WHO) shows that outdoor air pollution has become a major environmental health problem across the world. However, as people spend up to 90% of their time indoors , exposure to outdoor air pollutants is more likely to happen inside homes and other indoor environments .
With the recent uptick of respiratory diseases such as influenza and ever-evolving COVID-19 variants and strains, new approaches to protect our well-being must become part of the norm in safeguarding public health.
Air pollution from outside air can enter homes, schools, and other indoor environments through doors, windows, and other gaps in buildings . However, indoor air quality is also affected by indoor sources such as pet hair, home products like pesticides, mold, and even fumes from cooking .
Viruses like the flu and COVID-19 can also spread through the air in crowded, indoor, and poorly ventilated spaces . Exposure to indoor air pollution can cause allergies and asthma , or in the worst cases, cancer , heart disease , and other ailments that affect the brain or kidneys .
Controlling sources of pollution and ventilating spaces with outdoor air, if clean, are the most effective approaches for improving indoor air quality. When air pollutant source reduction and dilution by ventilation are insufficient or impractical, there are several measures also available such as the use of portable air purifiers with high efficiency particulate air (HEPA) filters .
Portable air purifiers that use HEPA filters as the primary mechanism of air cleaning offer many advantages over other air cleaning methods currently available for in-home use.
Studies find that air purifiers with HEPA filters have shown promise for improving asthma outcomes in children and adults . Intervention studies with HEPA-based air purifiers have also shown promise for improving nasal or rhinitis symptoms in adults and children with allergic rhinitis and/or conjunctivitis .
Indoor air purifiers vary greatly in terms of technology, operation, cost, energy usage and maintenance requirements. Among factors to consider are a device’s level of filtration technology, noise levels, ease of operation, real-time air quality monitoring, and a high airflow rate.
For clean indoor air at the push of a button, the Philips 800 Series Air Purifier quickly and effectively filters viruses, allergens, or pollutants in spaces up to 48 m². It uses multi-layer filtration technology present in all Philips Air Purification Solutions. The pre-filter catches dust and air, while the NanoProtect HEPA filter is designed to capture over 99% of particles as small as 0.003 microns, smaller than the smallest.
