Understanding Indoor Air Pollution and Its Health Impacts
Indoor Air Pollution: Sources and Types
Many people may think that air pollution is only an outdoor problem. But in reality Indoor air can be 2-5 times more polluted than outdoor air (according to the EPA - United States Environmental Protection Agency). Sources of indoor pollution are diverse, such as:
PM2.5 and PM10 dust: Small particulate matter that can penetrate the respiratory system and bloodstream.
Allergens: dust mites, pet dander, pollen, mold
Volatile organic compounds (VOCs): from house paint, furniture, cleaning products
Toxic gases: carbon monoxide, nitrogen dioxide from combustion
Pathogens: bacteria, viruses
Health Impacts: Short-Term and Long-Term
Prolonged exposure to indoor air pollution can have both short-term and long-term health effects:
Room Size: Measure the room size in square meters (width x length) to choose an air purifier of the appropriate size. If the room has a higher than normal ceiling (2.4 meters), consult a specialist.
CADR: is the rate of clean air delivery. Represents the amount of air that an air purifier can clean in one unit of time. (cubic meters per hour or CFM) A higher CADR value means faster air purification efficiency. You should choose an air purifier with a CADR of at least 2/3 of the room size.
Example: A 30 square meter room should choose an air purifier with a CADR of at least 200 m3/hr.
Filter Types
Pre-filter: Traps large dust particles such as hair and animal fur, helping to extend the life of the main filter.
HEPA filter (High-Efficiency Particulate Air): Traps PM2.5, PM10, and allergens at least 99.97% at 0.3 micron particles (US standard) or 99.95% (European standard).
Other specialized filters: such as filters coated with antibacterial agents, UV-C filters for disinfection.
Recommendation: For those with allergies or living in highly polluted areas. You should choose an air purifier with HEPA and Activated Carbon filters.
