High-Performance Filter Foam Solutions for Clean, Efficient Filtration – Trusted Manufacturer & Supplier

In today’s world of precision filtration, selecting the right filter foam can directly impact the performance, efficiency, and longevity of your system. At Dengyue Group, we specialize in producing advanced filter foam blocks engineered to meet the strict demands of air and liquid filtration across industries.

Our polyurethane filter foams are available in a wide range of PPI (pores per inch) values, offering fine-tuned performance for every filtration requirement—from coarse pre-filtration to ultra-fine biological filtering.

What Is Filter Foam?

Filter foam is an open-cell polyurethane foam designed specifically for filtration and fluid separation. Its unique structure allows air or liquid to pass through while capturing particles, debris, and contaminants. Depending on your filtration needs, foams with different PPI ratings are selected:

Low PPI (10–20): Coarse foam for initial filtration or mechanical separation.
Medium PPI (25–35): Balanced filtration for general industrial use.
High PPI (40–60+): Fine and ultra-fine foam used in sensitive systems like aquariums, air purifiers, and medical devices.
