Here are the key considerations of Consumer Council for consumers when choosing an air purifier in Hong Kong, a densely populated region where air pollution has been a major concern:
1. Clean Air Delivery Rate (CADR):
CADR measures the air purifier's ability to remove smoke, dust, and pollen.
The higher the CADR value, the faster the purification speed and performance.
Consumers should prioritize products with higher CADR values.
2. Actual Coverage Area:
Manufacturers often specify the room size the product is suitable for, but actual performance may vary depending on the pollution level.
Consumers should prioritize products that clearly state the CADR and testing standards, rather than just relying on the manufacturer's stated coverage area.
3. Formaldehyde Removal Effectiveness:
New furnishings or renovations can increase indoor formaldehyde levels, which can irritate eyes, ears, nose, and respiratory system, and cause allergic reactions.
The effectiveness of air purifiers in removing formaldehyde varies greatly, so consumers should consider other methods to reduce formaldehyde emissions.
4. Virus Removal Effectiveness:
The air purifier's ability to remove viruses can be affected by factors like placement, operating time, and room size.
Over time, the filter's performance may degrade, impacting the virus removal effectiveness, so regular filter replacement or cleaning is necessary.
Other Considerations:
Timely replacement and proper maintenance of filters are crucial to prevent the return of harmful substances like bacteria, viruses, or mold.
Air purification does not equal disinfection, and reducing air particle concentration may not necessarily alleviate asthma or other sensitive symptoms.
Improving indoor air quality requires controlling pollution sources and maintaining air circulation, not just relying on air purifiers.
For homes with windows facing busy roads, consider closing those windows or using them for exhaust only, and drawing in fresh air from cleaner windows.
Users should unplug the air purifier or use a dedicated power switch to reduce energy consumption.
In summary, when choosing an air purifier, consumers should consider the product's purification capability, coverage area, and effectiveness in removing harmful substances, in addition to their home environment, to find the most suitable option.
