Filter Technology
The complexities of managing emissions and ensuring smooth and efficient processes while controlling operational costs can significantly impact industrial operations’ performance and compliance.
At Donaldson BOFA, we understand the unique challenges of industrial processes and applications to provide solutions that make a difference and maximize productivity.
Through meticulous design and manufacturing, we are committed to delivering solutions that not only meet but exceed market expectations, helping to ensure your operations run smoothly and efficiently.
How Often Should You Change Your Fume Extraction Filters?
Regular filter replacement is essential to keep your Donaldson BOFA fume extraction system running efficiently and maintaining a clean workspace. How often you need to change your filters depends on your specific application and system usage.
As a general guide:
- Combined filters should be replaced every 12 months regardless of usage.
- Replace pre-filters and bag/HEPA filters when your system display or LED lights show a blockage.
These are only guidelines — actual replacement intervals can vary depending on your process and operating conditions.

Pre-filters
DeepPleat
The DeepPleat pre-filter consists of a pleated filter allowing for increased surface area within a smaller volume. This means Donaldson BOFA filters last for a long time and do not take up a large footprint.
DeepPleat DUO
Our DeepPleat DUO pre-filter is designed to maximize filter life. It incorporates a large capacity drop-out chamber within the filter which is designed to act as a pre-separator helping to extend the life of the pre-filter which in turn protects against the premature blocking of the HEPA filter.
Main filters
HEPA
Our HEPA filters are rated to filter 99.995% of particles at 0.3 microns. A secondary filter to remove fine particulate.
Chemical & gas
Our advanced carbon filters are designed to help filter fumes, with specific carbon types matched carefully to industry applications.
Contaminated air must remain in contact with the carbon bed for a period of time, sufficient to help ensure that no contaminants or odors are emitted (‘dwell time’). Our product designs consider the balance between airflow rates and the type, depth, and mass of the carbon used, taking into consideration the contaminants associated with the application and helping to ensure that appropriate dwell times are achieved.
Inline filters
Are you looking for inline filters? We offer a range of inline filters that are ideal for applications that generate high amounts of dust and particulate.
