How chaotic is the empty net industry in the past? Only 70% of products are now qualified
In the wake of several food safety scandals—such as tainted milk powder, recycled cooking oil, and water-injected pork—Chinese consumers have become increasingly sensitive to issues concerning their health and well-being. Any topic related to public health can spark intense debate across the nation. As autumn and winter approach, northern cities are once again grappling with severe air pollution. The term "smog" has become a hot topic on social media, with some people seeing it as an opportunity. For instance, the rise in smog has led to a surge in sales of air purifiers, benefiting manufacturers significantly.
Once considered the fifth essential household appliance after color TVs, refrigerators, air conditioners, and washing machines, air purifiers have gained popularity in recent years. However, unlike traditional appliances, they come with a sense of mystery. Many consumers remain confused about their effectiveness and standards, often feeling misled by exaggerated claims.
According to data from the China Consumers Association, 30% of air purifiers on the market failed quality tests. Despite this, the industry has seen steady growth, especially after the implementation of new national standards in 2016. In October 2016 alone, online sales of air purifiers reached 244,000 units, showing a significant increase compared to previous months and the same period the year before. During the "Double Eleven" shopping festival, sales hit 620 million yuan, reflecting a year-on-year growth of over 113%.
At a recent seminar organized by the China Consumers Association, Liu Qing, deputy secretary-general, highlighted that while the market is growing at a rate of 20–30% annually, 30% of products still fail to meet quality standards. This lack of consistency makes it difficult for consumers to make informed choices.
The confusion in the industry stems partly from high profit margins and low technical barriers. Many companies, including traditional home appliance manufacturers, have entered the market, leveraging their brand reputation to gain market share. Some even sell expensive purifiers without real expertise, relying on aggressive marketing rather than product quality.
Newer companies, lacking brand recognition, often offer ultra-low prices to attract budget-conscious buyers. However, some of these products may not be effective or could even worsen indoor air quality. This has led to concerns about misleading advertising and poor product performance.
To address these issues, the new national standard for air purifiers was implemented in March 2016. It aimed to clarify technical specifications and improve labeling. While the standard helped reduce market chaos, challenges remain. A 2016 national quality inspection found that only 70% of tested products met quality requirements, with brands like Bain and San Da being listed on the black list.
For consumers, choosing the right air purifier requires careful consideration. They should look for products that comply with the new national standards, clearly indicate CADR (Clean Air Delivery Rate), CCM (Cumulative Clean Mass), energy efficiency, and noise levels. It’s also important to verify claims such as formaldehyde removal through third-party testing reports.
Consumers should avoid assuming that higher price means better performance. Instead, they should choose based on their specific needs, such as room size and purification requirements. Not all devices labeled as "dehumidifiers" effectively remove harmful pollutants, so it's wise to select models with high CCM values for formaldehyde removal.
Proper use and maintenance are equally crucial. Filters should be cleaned or replaced regularly to prevent secondary pollution. Obstructions at the air outlet should be avoided, and electrostatic filters need regular cleaning.
In summary, the air purifier market is still plagued by inconsistencies in performance and quality. Many small brands struggle with after-sales service, leaving consumers without support or replacement parts. Some products even become sources of secondary pollution. While the industry has made progress, it still needs further regulation. Consumers are advised to prioritize well-known brands over cheap alternatives, ensuring better quality and long-term reliability.
