With many years of experience in the design and manufacture of washable polyurethane filters, Serf continues to excel in the quality and innovation of its products. These filters, called 'Long-Life' on our website, are an advanced solution for clean air and reliable performance.

Made of a 10mm layer of polyurethane foam impregnated with activated carbon and covered with a black fabric, Long-Life filters offer high efficiency and an extended life cycle of up to 3 years. Thanks to the possibility of assembling several layers, they can be adapted to specific customer requirements, confirming Serf's focus on customisation and customer satisfaction.

A practical and sustainable regeneration system:

The real strength of Long-Life filters is their regenerability. They do not require frequent replacement, but can simply be washed in a dishwasher (without detergent) at a maximum temperature of 60°C for 10 minutes, then dried in an oven at 60°C for 40 minutes and finally air dried. This process, which can be repeated up to 8 times, ensures long filter life and maximum efficiency.

With decades of experience and a constant focus on innovation, Serf confirms its role as a benchmark in the filtration sector, offering products that combine functionality, sustainability and durability.
