Air purifiers are powerful air cleaning devices with excellent efficiency in capturing particulate matter and airborne pollutants. However, not all air purifiers have the technology capable of removing odors and gaseous emissions, which can cause irritable symptoms more heightened than particulate matter.
For comprehensive air quality protection, understanding air cleaning technology, types of airborne particles, and the health impacts they carry help minimize harmful pollutant exposure.
What particles do air purifiers remove?
Standardized HEPA air purifiers remove and filtrate common indoor pollutants up to 0.3 microns in size at an efficiency rate of 99.97%, including pollen, dust, and pet dander. For advanced ultrafine particle filtration, HyperHEPA air purifiers capture and remove microscopic pollutants as small as 0.003 microns at a rate of 99.5%, such as:
- Smoke
- Traffic emissions
- Bacteria
- Viruses
- PM2.5, particulate matter up to 2.5 microns in size, particulate matter up to 2.5 microns in size
- PM10, particulate matter up to 10 microns in size
However, neither HEPA or HyperHEPA filters are capable of filtrating odors. To capture and remove airborne odors, air purifiers must be equipped with activated carbon filters and a multilayered filtration structure to fully eliminate odor particles and gaseous emissions.
What air purifier removes odors?
Activated carbon filters are advanced air cleaning tools made of a highly porous, dense structure that captures airborne odors and gaseous emissions through tiny pockets on the filter’s surface. Activated carbon air purifiers are unlike the HEPA filtration systems, specifically targeting invisible gases and harmful scented products instead of particulate matter, such as:
- Cooking odors
- Scented cleaning sprays
- Scented candles
- Volatile organic compounds (VOCs)
- Formaldehyde
- Carbon monoxide
By employing multilayer filtration with activated carbon and HyperHEPA filters, comprehensively clean air quality can be achieved and the maximum amount of airborne pollutants removed. Without full coverage air cleaning, pollutants can linger and affect your breathing (1).
How do airborne pollutants and odors impact health?
Especially in polluted urban cities and environments, insufficient air filtration and ventilation cause poor indoor air quality, leading to elevated health risks. Long-term exposure to particulate matter can cause respiratory complications, heart disease, and heightened Chronic Obstructive Pulmonary Disease (COPD) symptoms (2). Air quality events, such as wildfires or cultural crop burnings, can increase these levels of particulate matter exposure. Air quality events, such as wildfires or cultural crop burnings, can increase these levels of particulate matter exposure.
Scented cleaning products, kitchen gases, and indoor odors can cause similar health effects if air quality is left untreated, such as nasal irritation, asthmatic symptoms, and liver damage (3). To protect against all pollutant types, multilayered air cleaning technology is needed.
Do air purifier filter types matter?
Yes, air purifier filter type greatly influences the type of particles that are removed and the efficiency rate the system performs at. To properly remove airborne odors and gaseous emissions, employ air purifiers with activated carbon. To capture and filtrate particulate matter, utilize HEPA filtration systems, and HyperHEPA filters to deal with microscopic pollutants.
For defense against all airborne pollutants and comprehensive air quality protection, equip a multilayered air purifier with both activated carbon and HyperHEPA filters to capture the maximum amount of harmful particles.
Clean air methods for removing odors
Even with the assistance of an air purifier, odors and gaseous emissions can be difficult pollutants to deal with, especially since they can be tricky to spot. Utilizing air filtration tools in conjunction with daily practices and cleaning is the key to limiting pollutant exposure before it can even happen. Routine clean air methods limit the presence of harmful particles indoors, such as:
- Odor source control: Avoid scented household aerosols, install air quality monitors in high gaseous emission areas, and keep cigarette smoking outdoors.and keep cigarette smoking outdoors.
- Advanced filtration: Run air purifiers throughout the day, utilize advanced activated carbon filters, and employ multiple air cleaning systems for high pollutant areas.
- Ventilation awareness: Open windows during food preparation, employ hood fans when cooking, and utilize HVAC systems to increase airflow circulation.
By employing multilayered air cleaning technology alongside daily practices and monitoring, odors can be stopped before they become airborne, and clean air quality can be achieved through maximum pollutant protection.
The takeaway
Air purifiers are efficient air cleaning tools that can remove odors, gaseous emissions, and chemicals from indoor spaces, but only when equipped with the proper filtration technology. Activated carbon filters are the most optimal choice to eliminate a wide variety of harmful odors and gases, though a multilayer filtration approach is suggested for maximum air quality protection. harmful odors and gases, though a multilayer filtration approach is suggested for maximum air quality protection.
Utilize air purifiers with multilayered filters in conjunction with daily air cleaning practices to create a space that is both pollutant-free and odor-free.
Frequently Asked Questions (FAQs)
Do all air purifiers remove odors?
No, not every air purifier filtration system is capable of removing odors.
To address indoor odors, utilize activated carbon filters or seek air purifiers that are specifically designed to remove odor particles. Activated carbon air purifiers contain a uniquely dense, porous filter structure that is excellent in capturing and neutralizing gaseous emissions and odors. Standard HEPA and HyperHEPA filters are inefficient in removing indoor odors.
How do I know if an air purifier removes odors?
Double check product packaging and filter type to ensure the air filtration system and device are capable of removing airborne odors. Try running the air purifier between different rooms to see if the device removes any lingering odors or smells.
To scientifically ensure clean air quality, install an air quality monitor to keep watch on pollutant particle levels.
How long do air purifier filters last?
Air purifier filters can last anywhere between 6 months to 4 years, depending on model, size, pollutant levels, and daily utilization.
Where do indoor odors come from?
Invasive and irritable odor emissions can be produced by multiple different outdoor and indoor sources.
Within indoor spaces, odors can originate from combustion, such as cooking odors and scented candles, or harmful household products, including scented cleaning sprays and body mists. Odors can also creep inside through outdoor origins, like vehicle emissions and animal activity.
