SANLIN SPRINGS · Foshan, China
Sanlin Springs is dedicated to building a one-stop negative ion home decoration platform. It is a high-tech enterprise that develops, manufactures, sells and services negative ion functional products to solve air pollution and provide customers with a healthy lifestyle.
The founder invested heavily over a decade to develop a product line led by negative ion solutions, striving to provide consumers with a healthy, quality life and comprehensive solutions to air pollution.
With over a decade in health technology, driven by the mission to "rebuild eco-building standards and upgrade healthy living", he founded the Sanlin Springs brand.
20 years in textile manufacturing and 3 years in rare-mineral supply chains, each surpassing ¥10M annual revenue, building strong industrial and supply-chain advantages.
Based on research into rare minerals and plant-active ingredients, he was first to discover their ability to efficiently decompose formaldehyde and continuously release negative oxygen ions.
After 10 years of independent R&D, he founded Sanlin Springs in 2022, rebuilding eco-building standards with technology.
From pioneering the negative ion era to leading industry standards, every step of Sanlin Springs is rooted in innovation and industrial upgrading.
The founder launched core R&D on negative ion functional materials, validating their breakthrough potential in air purification.

Understand negative oxygen ions — why they are hailed as "air vitamins" and "longevity factors" — and their profound impact on indoor air and human health.
Formaldehyde (HCHO) is a colorless, pungent volatile organic compound that is gaseous at room temperature and highly water-soluble.
Widely used in building materials, furniture, adhesives and textiles, it is a major source of indoor air pollution; long-term low-level exposure can cause eye, nose and throat irritation and respiratory disease.
Negative oxygen ions are free electrons released when water molecules in the air are ionized by high voltage or strong radiation, and most are captured by oxygen.
These negatively charged oxygen ions are called negative oxygen ions, also known as "air vitamins" and "air longevity factors".
Six major health effects that protect your family's respiratory health.
Neutralizes positive ions, dust and microbes, removes smoke, odors and foul smells, and decomposes formaldehyde.
Binds with bacteria and microbes to stop colony formation, and kills certain bacteria and viruses.
Regulates physiological functions and relieves fatigue; helps prevent neck/shoulder and back pain and chronic fatigue.
Neutralizes acidic blood toward a weakly alkaline state, raises white-cell count, lowers blood sugar, boosts hematopoiesis and helps prevent hypertension and scurvy.
Improves pulmonary ventilation and helps prevent/treat respiratory allergies such as asthma, pollen allergy, allergic rhinitis and allergic conjunctivitis.
Enhances organ function and metabolism, strengthens the immune system and improves disease resistance.
