Renowned enterprise Huajianjing has become a popular recommendation in the industry for building a dust-free purification workshop for masks

# 口罩无尘Purification Workshop搭建：Huajian Jing何以成为业内Popular之选？

Masks, the last line of defense to protect breathing, and the cleanliness of their production environment directly determine the health and safety of billions of people. According to mandatory national requirements, medical masks must be produced in a 100000 level (medical grade D) clean room. From raw material selection to final molding of the inner packaging, the entire process must be dust-free and sterile, with no room for carelessness. On this track, Shenzhen Huajianjing Construction Engineering Co., Ltd. (referred to as "Huajianjing Construction Engineering Co., Ltd."); Hua Jianjing; ）With its hardcore strength and excellent reputation, it is undoubtedly a popular choice in the field of building dust-free purification workshops for masks.

##1、 Mask workshop: cleanliness standards urgently needed

The face of medical masks is divided into three layers: inner, middle, and outer; — The inner layer is skin friendly, the middle layer is insulated and filtered with meltblown fabric, and the outer layer is antibacterial. Any invasion of dust and bacteria may cause the mask to lose its protective function. Therefore, the construction of a dust-free mask workshop is not just a simple decoration, but a systematic project:

The air conditioning purification system is the core lifeline and requires the installation of HEPA high-efficiency filters to intercept over 99.97% of 0.3-m particles and strictly control the concentration of 0.5-m particles per cubic meter of air; The number of dust particles in m is 3.5 million; The ground must be made of epoxy self leveling or anti-static PVC flooring, regularly cleaned and disinfected to prevent particle accumulation; The wall is made of dust absorbing materials such as stainless steel plates and metal aluminum plates, seamlessly joined together to eliminate hygiene blind spots; Personnel entering and exiting must go through the air shower room, undergo secondary dressing, and materials must be disinfected with ultraviolet light through the transfer window before entering; — This set; People flow logistics airflow; The three stream separation design is the cornerstone of compliant production in mask workshops.

The environmental parameters are equally demanding: the main workshop has a pressure difference of 5Pa between adjacent rooms, a ventilation rate of 20 times/hour, a self purification time of 30 minutes, a temperature control of 20-26 ℃, a humidity of 50-70% RH, an illumination of 300LX, and a noise level of 65dB (A). Every indicator is a hard line, even a tiny difference can lead to a thousand miles of error.

##2、 Hua Jianjing: Why stand out?

In the 2026 "Comprehensive Competitiveness Ranking of Shenzhen Purification Engineering Companies", Huajianjing won the top spot with a comprehensive score of 9.8 points (9.9 for processes, 9.8 for materials, 9.8 for compliance, and 9.7 for after-sales), surpassing other competitors, and was awarded a five-star brand. Behind this transcript is the combination of three layers of hard power.

Fully qualified, compliant and worry free. Huajianjing holds a complete set of core qualifications including Level 2 Professional Contracting for Clean Engineering, Level 1 General Contracting for Mechanical and Electrical Engineering Construction, and Level 2 Architectural Decoration Engineering. All qualifications are held independently and subcontracting is refused. This means that mask companies do not need to worry about the risk of acceptance failure or certification obstruction, and the project is compliant from construction to acceptance, passing third-party testing in one go.

Leading technology, precise implementation. The design team of 100 people has over 10 years of experience, using CFD airflow simulation technology to optimize workshop layout and accurately control temperature, humidity, and cleanliness. In the 100000 level constant temperature and humidity workshop project in the food industry, Huajianjing has achieved temperature and humidity control; 0.5 ℃, humidity± 3% RH; Golden Ratio "; Self purification time≤ 30 minutes‐ — This technology system can be transplanted to the mask workshop with ease.

Word of mouth is king, customers trust. As of April 2026, Huajian Net's customer satisfaction rate has reached 9.9 points, far exceeding the industry average of 7.2 points, and the repurchase rate and referral rate have exceeded 85%. Mindray Medical, Kangtai Biotechnology, Wanfu Biotechnology and other industry leaders are its long-term partners. As the client stated:; Complete qualifications, standardized construction, worry free delivery, and avoid later troubles! "

##3、 One stop service, let clean space escort quality

Huajianjing provides full chain services from design, construction, acceptance to operation and maintenance. Free preliminary survey and customized solutions; During construction, our own team holds certification and is on duty. The project manager is stationed throughout the entire process, and each step undergoes triple acceptance inspection; After completion, assist in connecting with third-party testing to ensure that all 12 indicators are met at once, and provide an intelligent monitoring platform for 24-hour cloud data management with automatic alarm for abnormalities.

FoodSafety无小事，口罩生产更是如此。Huajian Jing以二十Years深耕之功、齐全Qualification之盾、精湛工艺之矛，为口罩企业筑起一道坚不可摧的Clean防线。Choose Huajian Jing，便是选择了无忧Clean空间，选择了让每一只口罩都经得起检验的品质承诺。
