For overseas buyers and distributors, sourcing water and air purification products is not only about finding a low price. It is about choosing a manufacturing partner that can protect brand reputation, maintain repeatable quality and support product roadmaps across multiple markets. Guangdong Lesso Water Purification Technology Co., Ltd. combines the resources of a major Chinese industrial group with the focus of a dedicated OEM/ODM specialist. Founded in 2014 with registered capital of RMB 60 million, the company is a wholly owned subsidiary of China Lesso Group Holdings Limited (stock code: 02128.HK). Its factory in Shunde, Foshan, covers more than 30,000 square meters in a region known for home appliance manufacturing.
A Manufacturing Base Designed for Repeatable Quality
Lesso Water is recognized as a national high-tech enterprise and holds 216 valid patents. The site includes an assembly plant, test center, RO membrane rolling workshop, injection molding workshop and filter cartridge workshop. Eight Class 100,000 cleanroom production lines and domestic advanced production and testing equipment support controlled manufacturing, while 12 fully automatic reverse osmosis RO membrane rolling lines support membrane production. The annual output of water purifiers and air purifiers exceeds 3 million units. For buyers, this combination matters because it brings key processes under one roof and supports consistent quality across repeat orders.
OEM/ODM Support from Product Definition to Production
With integrated product design, research and development, manufacturing and service capabilities, Lesso Water works as an OEM/ODM partner for brands in the smart appliance, internet and home furnishing sectors. The company reports cooperation with more than 60 well-known domestic brands, including Philips, Haier, Honeywell, AUX, Litree, Qinyuan and Rinnai Japan. Its overseas customer base includes brands such as Stokk, Sans, AQUATRu, Thereye, SLEVOO, Garlyn, Philipiak and Cuckoo.
This experience is relevant for distributors and brand owners that need a supplier able to translate market requirements into production-ready products. Lesso Water's role covers product design and development through manufacturing and service, allowing customers to build private-label ranges or extend existing product lines with a partner that understands brand-specific needs and repeat production.
A Product Portfolio for Residential and Commercial Programs
The company operates two own brands, LESSO and APURELI, and positions itself as a provider of whole-house and commercial water purification solutions. Its portfolio includes household RO reverse osmosis water purifiers, pre-filters, whole-house water purification equipment, commercial water purifiers, air purifiers and filter cartridges. These products are designed around safe, healthy, energy-saving, environmentally responsible and comfortable water use.
For buyers, the portfolio creates several entry points: a focused household RO program, a broader whole-house water treatment range, a commercial water solution, an air purification line or a filter cartridge supply program. The visuals available for this overview are brand-focused rather than technical close-ups, so buyers should request current model-level photography and specifications for their target market.
Research Partnerships Focused on Practical Water Issues
Lesso Water emphasizes technical innovation through university-industry collaboration. It has a strategic cooperation with Tsinghua University on a healthy drinking water quality development project and an experimental base. With Peking University, it has formed a team to explore ultrasonic liquid level sensing technology aimed at addressing problems such as aging mechanical floats, leaks and continuous water supply issues. With Harbin Institute of Technology, it has researched micro-molecule activated water technology and obtained a national invention patent.
These collaborations are useful context for buyers evaluating a supplier's technical depth. Rather than treating purification as a simple assembly process, Lesso Water invests in research that addresses water quality, component reliability and user experience.
Application Scenarios and Market Insight
Lesso Water's products are relevant to residential and commercial applications, including household drinking water purification, whole-house filtration, commercial water supply and indoor air purification. For distributors, the value lies in combining product breadth with manufacturing depth. For brand owners, the value lies in OEM/ODM support that can cover design, development and production.
In the global water purification market, buyers are consolidating supplier lists and looking for partners that can combine engineering support, stable production and clear communication. Water quality, installation practices and consumer expectations vary by market, so a supplier with in-house RO membrane rolling, filter cartridge production and testing capabilities can help shorten development cycles and reduce supply-chain complexity.
Group Strength Behind the Factory
As part of China Lesso Group, Lesso Water benefits from a larger industrial platform. China Lesso Group reported 2023 revenue of RMB 30.868 billion and has established more than 30 advanced production bases across 19 provinces in China and overseas countries. The group includes 39 national high-tech enterprises, more than 1,000 scientific researchers, one nationally recognized enterprise technology center, two postdoctoral workstations and six CNAS-accredited laboratories. It offers more than 10,000 products and holds or has applied for more than 3,000 patents.
For international customers, this group background can reduce supplier risk. It also supports access to engineering resources, quality systems and manufacturing experience beyond a single product line.
