Custom-engineered reticulated polyurethane foam for superior air & liquid filtration across industries.
Karefoam is a leading manufacturer of reticulated filter foam solutions in India, offering cutting-edge foam technology tailored for high-efficiency filtration. Our polyurethane filter foam is engineered through a precision reticulation process, creating an open-cell structure ideal for capturing particles, improving airflow, and allowing rapid drying. Whether you're in automotive, medical, HVAC, marine, or outdoor applications, Karefoam delivers performance and durability that sets the benchmark. As one of India's established filter foam manufacturers, we also supply dedicated air filter foam grades for industries that demand consistent filtration performance.
Reticulated filter foam is a specialized form of polyurethane foam that has undergone a controlled reticulation process. This method removes the cell membranes, leaving behind a 3D lattice of interconnected strands creating an open-cell foam with exceptional porosity. It is used for both air and liquid filtration in various industries. This open-cell structure is typically produced as a filter foam sheet before being converted to the size or shape a customer needs.
