For the mechanical pre-filtration of fine dirt particles

Sera filter wadding for mechanical pre-filtration consists of strong fibers that retain fine dirt particles for a long time without sticking or breaking down. The cotton wool may need to be rinsed several times. Suitable for all filters.

Before the first use, it is necessary to rinse the filtration media sera with hot water.
