NEIDERT LUFTFILTERTECHNIKNEIDERT LUFTFILTERTECHNIK GmbH, founded in 1983 with headquarters in Essen, Germany is a family-owned producer and distributor of standards-compliant air filters. NEIDERT LUFTFILTERTECHNIK HVAC air filters, filter mats and HEPA filters are used in offices, production facilities, swimming pools, medical and laboratory areas and the food industry.


In 2015 NEIDERT LUFTFILTERTECHNIK examined their manufacturing process to improve production efficiency. They decided to focus on manufacturing their own speciality products and partner with an external supplier to manufacture and provide a regular stock of pre-welded rolls and a range of bag filters. Irema was chosen as the company’s standards-compliant filter partner.
The welded rolls have 6 rows of internal spacers to enable the end product (pocket filters) to inflate and distribute airflow evenly.
