Paper Filter

We are a “Specialized, Sophisticated, Distinctive, and Innovative (Little Giant)” high-tech enterprise focused on air filtration. We specialize in the R&D, manufacturing, and sales of household, commercial, and industrial air filters and purification equipment, and provide one-stop integrated air-purification system solutions.

In 2013, a group of entrepreneurs with a dream of purifying the air set out on their journey in Shanghai. As the business expanded, LANSIR established a new production base in Jiangsu in 2021 and embarked on group-based operations. The following year, we built a high-standard cleanroom and testing laboratory, always putting quality first.
