Air purifiers can significantly improve indoor air quality by reducing various pollutants. After home renovations, harmful substances such as formaldehyde, dust, and odors are often released into the air, which can be dangerous to health. Many consumers choose air purifiers to enhance air cleanliness. These devices not only remove pollutants like PM2.5, dust mites, and allergens but also eliminate bad smells and even generate a small amount of ozone to freshen the air. They use physical filtration, chemical decomposition, and adsorption to clean the air effectively.
With hundreds of brands available on the market, many claim to remove 99% of formaldehyde or PM2.5. According to data from 2014, over 300 companies entered the air purifier industry, and sales grew by nearly 70% year-on-year. While air purifiers do help reduce pollution, they should not be relied on entirely. The best way to ensure good air quality is to minimize pollution sources at the source.
However, low-cost counterfeit products may cause secondary pollution. Some fake air purifiers use substandard materials and poor design, leading to ineffective purification or even worsening indoor air quality. These products often mimic well-known brands in appearance but lack safety and performance. Their filters may not work properly, allowing pollutants to pass through or even release harmful particles back into the air.
When purchasing an air purifier, it's important to consider key factors like CADR (Clean Air Delivery Rate), which measures how efficiently the unit cleans the air. Other important aspects include the applicable room size, formaldehyde and PM2.5 removal efficiency, bacterial removal rate, energy efficiency rating, noise level, power consumption, and filter lifespan. New national standards have raised the bar for air purifier performance, making it more important than ever to choose a reliable product.
During use, air purifiers can dry out the indoor air, so it’s advisable to place a few water bowls nearby. If using a humidifier, keep it at a distance and limit its operation time to protect the purifier’s filters. Always place the unit on a flat surface to avoid motor damage. Regularly check and replace the filter if it becomes too dusty.
Experts recommend choosing air purifiers with third-party testing certificates and medical-grade certifications for better reliability. While foreign brands may have some advantages, domestic models are often better suited for local conditions. When buying, prioritize effectiveness, after-sales service, and cost-performance ratio. A well-chosen air purifier can make a real difference in your living environment.
