Four filtration layers.
Two treatment technologies.
A clear description of the six-stage configuration supplied with Crusaders’ six-stage models.
Filter what passes through.
A pre-filter, HEPA H14, activated carbon and photocatalyst layer form the four filtration components. Each has a distinct role in the air-treatment system.
- Pre-filter for larger dust, hair and lint.
- HEPA layer for fine airborne particles.
- Activated carbon for odours and certain gases.
- Photocatalyst layer within the active treatment system.
Treatment beyond filter layers.
UV and plasma-ion technology complete the six-stage configuration. These are treatment technologies rather than two extra physical filters.
Our team can walk you through the supplied components, how the selected model operates and what will require replacement over time.

Know before you choose.
How should I select a room air purifier?
Start with the room area and ceiling height, then consider occupancy, ventilation and operating hours. Ask for the model’s airflow, filter configuration and replacement costs before purchasing.
What should I check about replacement filters?
Confirm the correct filter part, price and availability for your model. Replacement timing depends on usage and the indoor environment, rather than a single interval for every customer.
Do you supply homes as well as institutions?
Our team handles residential, corporate and institutional requirements. Share your application and quantity so we can discuss the appropriate options.
