LTB AG

The company LTB AG has its origins in Liestal (BL) and has successfully combined innovations with technology, know-how, and Swiss precision for over 30 years. The company is considered one of the most reliable filter manufacturers not only in the Basel region but throughout Switzerland. With two additional production sites in the cantons of Fribourg and Jura, LTB AG is also well-connected in Western Switzerland. All manufacturing stages, from development to processing to the final assembly of a filter, are carried out in-house. As a family-run, financially independent SME, the company focuses on innovative products, customer proximity, and quality. Our filters are exclusively manufactured in Switzerland and therefore meet high quality standards. This is evident, among other things, in excellent filter performance and lifespan. Additionally, we have had our products tested by an independent testing institute, the Technical Research Institute of Sweden (SP). SP Technical Research Institute of Sweden is authorized to conduct tests according to EN779:2012 and classify the filters into energy efficiency classes (A, B, C, D, and E) according to Eurovent. We have marked our products with special energy-saving potential.
