Hammer Technology’s 2017 Autumn New Product Launch took place on November 7th at the Chengdu Magic Square Performing Arts Center. This event marked the official debut of the brand "Smooth Breathing," a new sub-brand under Hammer Technology. During the launch, three innovative products were introduced: the Smooth Breathing Smart Air Purifier, the Breathable Anti-Fog Mask, and the Chang Breathing Car Air Conditioning Filter. Among these, the Smart Air Purifier stood out as one of the most anticipated releases in the air purification industry that year.
The Smart Air Purifier boasts an impressive CADR (Clean Air Delivery Rate) value of 800 m³/h, making it one of the most powerful air purifiers available at the time. Priced at 3,499 yuan, it quickly captured attention for its high performance and reasonable cost. The product not only delivers rapid and efficient air purification but also sets a new benchmark for the industry by redefining the standard of “clean air per hour.â€
One of the standout features of the Smart Air Purifier is its noise control. Whether used during the day or at night, it operates within an acceptable noise range while maintaining top-tier purification efficiency. At night, the purifier runs at just 34 dB, equivalent to the quiet environment of a library, yet still provides a purification rate of 205 m³/h. This makes it ideal for long-term use, especially in bedrooms or other spaces where silence is essential.
In terms of filtration, the Smart Air Purifier is equipped with a long-lasting, high-quality filter. The CCM (Cumulative Cleanliness Measurement) value for particulate matter reaches 50,000 mg, which is more than four times the national standard. For formaldehyde, the CCM value exceeds twice the highest level of the standard. Its three-layer filter design effectively removes particles, hair, secondhand smoke, formaldehyde, toluene, and other harmful substances, capable of purifying over 160,000 cubic meters of heavily polluted air.
Designed with a minimalist aesthetic, the Smart Air Purifier blends seamlessly into any home environment. Its sleek, low-key design retains all the necessary details, offering both functionality and elegance. The unit is available for purchase through multiple channels, including the official website of Changping Respiratory Technology, Jingdong Mall, Suning Tesco, Taobao Electric Field, and Amazon.
The concept of “ERANL†(Effective Room Size at Acceptable Noise Levels) was introduced to better measure the real-world usability of the purifier. While traditional models operate at higher noise levels, the Smooth Breathing Smart Air Purifier maintains a balance between power and quiet operation. For instance, during the day, it can effectively clean up to 18.9–32.4 m² at noise levels below 45 dB, and at night, it can cover 14.35–24.6 m² at noise levels under 35 dB.
The purifier also features six different operating modes, including sleep mode, manual settings, and extreme mode. In sleep mode, it operates at 34 dB, providing a peaceful atmosphere while still delivering strong purification. In manual mode 4, it achieves a CADR of 600 m³/h at 60 dB, cleaning a 20 m² room in just 5 minutes.
Equipped with a high-precision laser dust sensor, the Smart Air Purifier accurately detects PM2.5 levels and displays them on the front panel or via a mobile app. Users can easily monitor air quality through color indicators—green for clean, orange for moderate, and red for poor air quality.
Beyond the air purifier, the “Smooth Breathing†brand also launched the Breathable Anti-Fog Mask and the Chang Breathing Car Air Conditioning Filter. The mask comes in five colors and is priced at just 9.9 yuan, while the car air filter, designed to remove pollen, dust, and odors, is available for 99 yuan. Both products are now available on the official websites of Hammer Technology and Changpeng.
Overall, the Smooth Breathing Smart Air Purifier represents a significant leap forward in air purification technology, combining high performance, quiet operation, and smart design to meet the needs of modern households.
