When it comes to primary filtration (also named as pre-filters), they are normally installed and applied in the 1st stage of filtration and capture larger particulates before reaching the HEPA filters. This is to reduce the large particles directly through the HEPA filters and extend the lifespan of HEPA filters.
To catch larger particulate matters such as dust, hair, dander, pollen, lint, dust mites and other harmful substances.
They are widely applied on all types of HVAC systems.
