On the evening of October 19th, the *Consumer Claims* program aired. During the segment titled "Quality of China," a blind test was conducted on several air purifiers from both Chinese and international brands, all priced between 3,000 to 4,000 yuan. The evaluation focused on performance, filtration efficiency, and user experience. To our surprise, the Lek Air Purifier KJ-703A was among the tested models and performed exceptionally well!
So, is the KJ-703A really as good as the test results suggested? To ensure the reliability of the blind test, Xiaobian decided to conduct his own independent testing using professional equipment.
In the experiment, a smoke cake was burned in a sealed chamber, raising the PM2.5 level to 195 μg/m³. After turning on the Lek KJ-703A for just 10 minutes, the PM2.5 concentration dropped to 0.039 μg/m³—far better than the results shown in the TV program. This confirmed that the KJ-703A is not only reliable but also highly effective.
Xiaobian, who had only seen the product briefly in the video, now gets a clearer view of its true potential. In fact, the KJ-703A is more than just a good air purifier—it's a real powerhouse!
For those looking for even stronger performance, the Lek Magic Net K9 is the flagship model in the company’s lineup. It offers advanced features and superior value, making it a top choice for modern households.
**2017 New Product**
Today, the main indoor air pollutants in Chinese homes are smog and formaldehyde. Based on this, Lek has developed the Magic Net K9, which combines high-energy centrifuge technology, low wind resistance, and high-efficiency HEPA filters. It also features an innovative formaldehyde decomposition system, making it one of the most powerful air purifiers available.
In an indoor environment, pollutants come not only from outside sources like PM2.5 and dust but also from smoking. Studies show that smoking three cigarettes in a 35m² room can raise PM2.5 levels to 1,700 μg/m³. The Magic Net K9 has a clean air delivery rate (CADR) of 950 m³/h, allowing it to quickly remove large particles. For a 100m² space, it can complete full purification in just 15 minutes.
The Magic Net K9 also boasts a formaldehyde CADR of over 600 m³/h, which is six times faster than standard purifiers with a CADR of 100 m³/h. Its formaldehyde removal capacity reaches up to 12,000 mg, eight times higher than the national F4 standard. This makes it ideal for long-term, effective aldehyde removal.
Additionally, the Magic Net K9 features high-precision laser sensors for PM2.5 and COâ‚‚. These sensors provide real-time monitoring and display of indoor air quality, helping users decide when to open windows for ventilation.
Currently, many domestic brands are focusing on solving real air quality issues. As a result, their performance is not inferior to foreign brands, and in some cases, even exceeds them. With data-driven evaluations, certifications, and rising consumer awareness, choosing an air purifier has become more rational than ever.
Lek Magic Net has obtained authoritative certifications:
It not only surpasses the new national standard for air purifiers but also meets the American AHAM certification, one of the most respected third-party testing organizations globally.
