The foam mats provide not only for a large surface for settlement but also for a perfect mechanical as well as biological filtration. They are resistant to ozone and oxygen and can be used up to 120°C.
The low-weighted CFC-free and recyclable foaming is used not only in garden pond filters but also in aquatics. The filter foam is characterized by a high durability and is absolutely neutral to water. There are no substances dispensed to the water. Due to its high compressive strength and a high bulk density, the filter foam is very stable and well-suited for the construction of “Hamburg filter mats” (HMF) and can be universally used for any interior or external filters.
The high-quality polyester-based filter foam disposes of an extremely large surface for the settlement of bacteria. Mosses and ferns grow easily on the filter foam´s surface to the effect that the same can be integrated unobtrusively into the overall picture.
