Pre-filter
The first layer for larger particles such as dust, hair and lint.
Air purification technology
Four filter layers.
Two treatment technologies.
Four filtration layers — pre-filter, HEPA H14, activated carbon and photocatalyst — work alongside UV and plasma-ion treatment to form Crusaders’ six-stage configuration. Here is what each component contributes.
HEPA H14 filter
A fine-particle filtration layer. Confirm the filter grade and model-specific specification with our team.
Activated carbon
An adsorbent layer used for odours and certain gaseous pollutants. Capacity depends on the filter and operating conditions.
Photocatalyst
A TiO₂ photocatalyst stage within the air-treatment configuration.
UV treatment
An integrated treatment stage. Confirm its specification and operation for your selected model.
Plasma ions
Ionisation technology completes the six-stage configuration. Ask our team about model-specific operation.
Filtration and air-treatment stages have different functions. This overview does not substitute for model-specific test reports or specifications.
CHOOSE WITH THE FULL PICTURE
Look beyond
the stage count.
Room volume, airflow, operating conditions and maintenance all affect the suitability of an air purifier. A stage count alone does not describe performance.

- What room size and volume is the model intended for?
- What are the listed airflow and available test reports?
- Which filters are supplied, and what do replacements cost?
- What are the service and warranty terms?
