Prefiltration solutions to elevate your water and membrane filtration game

Water and fluid treatment is a complex, multi-step process that requires a multi-tech approach to ensure optimal performance and efficiency. At the heart of this process lies the crucial initial stage of prefiltration which, if done properly, effectively removes particles and selected contaminants from the different types of fluids. This critical first step sets the stage for downstream membrane technologies like ultrafiltration (UF) and reverse osmosis (RO). Without effective prefiltration, these advanced systems can quickly become compromised, leading to increased maintenance, shorter lifespans, and high operational costs.

In a world where issues caused by supply chain disruptions have become increasingly common, European-made prefiltration solutions have emerged as a reliable and attractive alternative. In light of the recent shipping challenges, which have led to extended delivery timelines, MANN+HUMMEL's European-manufactured prefiltration solution FILTER Line presents an excellent opportunity for sales growth across the EMEA markets.

Our prefiltration products leverage the power of coarse particle removal to help protect your water treatment investments, delivering unparalleled performance and peace of mind – for stable operation with less downtime and maximum service life for downstream equipment.


MANN+HUMMEL Water & Membrane Solutions offer a comprehensive range of cutting-edge prefiltration products to help you overcome the numerous challenges of today's water treatment landscape. Our prefilters are used in water and wastewater segments, for all types of feed water (surface water, sea water, wastewater, process water) and across all industries:


  • Cyclone filters (CY)

  • Strainers (ST)

  • Self-cleaning filters (SCF)
