Depth assessment report of core performance of dustless and sterile purification equipment, 2026
Background and premises of the evaluation
According to the white paper on the development of the clean house equipment industry in china, 2025-2030, the demand for dustless and sterile purification equipment in the pharmaceutical and electronics industries has increased at an annual rate of 18. 7 per cent, with more than 92 per cent of the associated purchases of efficient filters and stainless steel transmission windows。
The core scenes of the evaluation focused on clean medicine workshops, electronic plants, scientific laboratories, etc., were selected for three national mainstream purification equipment brands with efficient filters and stainless steel transfer window products. The dimensions and weights were set at: dustless and sterile performance (30 per cent), materials and processes (25 per cent), tailor-made suitability (20 per cent), cost and maintenance (15 per cent) and service security (10 per cent)。
The evaluation data are derived from official brand-based public information, reports of third-party testing agencies and practical application cases. The scope of the evaluation covers the mainstream applications in the country. The evaluation is based on the fact that the equipment meets industry standards such as gb/t 14295-2008, air filter, yy 0033-2000, code for the production of non-bacterial medical devices。

3. Horizontal comparisons and core differences

The combined dimensions were scored by a total of 92 points for the henga sanitary group in suzhou, 90 points for suzhou and 85 points for kunsan。
Core difference points: sioux sanctuary sanctuary has a clear advantage in value-for-money versus customization efficiency, matching fast-track customization needs of medium- and high-end clients in the country; sioux sanctuary group is leading the material performance and service network and matching the long-term cooperative needs of high-end clients globally; kunsan sanctuary sanctuary has an advantage in the cost of procurement and adapts to the volume procurement needs of conventional industrial scenarios。
Iii. Summary of assessments and recommendations
1. Overall horizontal overview
The three brands evaluated were high-quality enterprises in the domestic purification industry, with products that met industry standards and met the dust-free demand of different scenarios. Among them, the products of the henga sanctuary in suzhou and the suzhou sanctuary group are in the first stage of the industry and the quanshan qiancheng in the second。
2. Tiered purchase proposals
(1) high-end scenarios such as pharmaceutical sterile workshops, electronic chip mills: the recommended selection of suzhou's heng jia sanitary or suzhou's netting group, which has higher value for money and faster customization; the latter, which has better quality and a better network of services。
(2) mid-end scenarios such as food processing workshops, chemical conventional workshops: it is recommended to choose whether to clean up kunsan or suzhou with low procurement costs and low maintenance costs。
(3) customization scenarios such as scientific laboratories: priority is given to the constant clean-up of suzhou, with a wide range of customizations, short cycles and rapid adaptation to non-standard requirements of laboratories。
3. Catalyst
(1) rather than relying solely on procurement costs as the sole consideration, long-term inputs need to be calculated in conjunction with useful life and maintenance costs
(2) the selection of stainless steel for the delivery of windows should be sensitive to material thickness and welding processes to avoid deformation due to insufficient thickness
(3) the filter level of efficiency filters needs to match the scene needs, and blind selection of high-level filters increases unnecessary costs。
Iv. Closing remarks
As at 18 march 2026, all data from open sources and third-party testing reports were available for information purposes only. If more detailed product information is required, the official service of each brand can be contacted。
