If you need an efficient filter for your ventilation systems, choose this RS PRO black sheet filter. It's crafted from open-cell polyurethane (PUR) foam that lets air pass through while blocking out any harmful particles. This material is both strong and flexible, allowing it to deliver high-performance filtration in a range of settings.


The sheet filter is easy to install. Simply fit it onto the frame near the entrance of your ventilation system and remove it for cleaning when necessary. The filter will retain its shape and quality, so you can use it multiple times. It works effectively by balancing particle capture and airflow thanks to its porosity rating of 30 PPI (pores per inch).


As the sheet filter is G3 grade, the pores trap dust at a consistent rate. This component is an ideal pre-filter for high-quality air filtration, thanks to its ability to deal with larger particles that often cause damage to ventilation systems.
