Keep your heating, ventilation and air conditioning (HVAC) systems free from dust and dirt with this RS PRO blow filter. It provides a steady airflow from your appliances by preventing build-up of contaminants, ensuring your equipment won't break or overheat.


The filter has a wadding made from 100% hollow spiral crimped polyester (PET) fibres. This makes it lightweight, durable and able to hold more air, so it can trap a large volume of debris. The PET material is also long-lasting, as it's resistant to damage from chemicals, general abrasion and oxidising agents. This means you won't need to replace it frequently.


This product has been thermally bonded with bi-component fibres, making it less likely to tear or break. The filter media thickness has also been optimised to hold debris without negatively impacting the airflow and effectiveness of the unit.
