Filter compatibility is model-specific. Before choosing a replacement filter, check the exact model designation on your air purifier and compare it with the compatibility information for the filter.

Do not rely on similar product names or physical appearance alone. Filters for related AirgoClean® models can differ in dimensions, construction and filtration specification.

The article number provides an additional reference when different filter versions are available for similar appliances. Compare both the appliance model and the stated filter article number before ordering.

This is particularly important where multiple HEPA or combination-filter variants are available for the same model family with different filtration efficiencies.

Different replacement filters perform different tasks. HEPA filters are designed for high-efficiency particle filtration, activated-carbon filters adsorb selected odours and gaseous contaminants, and combination filters bring several filtration stages together in one component.

Pre-filters generally capture coarser particles and can support the downstream filtration system. Check the exact construction of the replacement filter for your appliance instead of assuming that all models use the same stages.

TROTEC replacement filters can be offered with different stated filtration efficiencies, even within the same appliance family. Compare the exact value and filter terminology given for the individual article.

A percentage value describes a defined filtration characteristic and should not automatically be converted into a different HEPA class or into a claim that the same percentage of contaminants is removed from an entire room.

A HEPA filter focuses on particulate filtration, while activated carbon is used for selected odours and gaseous contaminants. Combination filters can integrate both functions, but the exact design differs between products.

Activated-carbon filtration should not be interpreted as guaranteed removal of every odour or volatile compound. Performance depends on the filter design, contaminant, operating conditions and filter condition.

A compatible replacement filter is an accessory or consumable unless the individual appliance offer explicitly states that it is included. Compatibility therefore does not mean that the item is supplied with the air purifier.

When comparing an appliance and its accessories, check the scope of delivery separately from the available replacement-filter range.

Replacement requirements depend on the appliance, filter type, operating time and level of contamination. Follow the instructions for the exact air purifier and use any filter-status indication as intended by the manufacturer.

A fixed replacement interval should not be assumed for the complete AirgoClean® range. Filter loading and maintenance requirements can differ considerably between models and applications.

Some air-purifier systems use several filtration stages with different maintenance requirements. A component that can be cleaned or vacuumed should not automatically be treated in the same way as a disposable HEPA or activated-carbon filter.

Use the product instructions to determine which components can be maintained and which must be replaced.

Some AirgoClean® model families have replacement filters with different stated efficiencies or combinations of filtration stages. The appliance name alone is therefore not always sufficient to identify the required filter variant.

Check the complete product description, article number and filtration specification before purchasing a replacement.

Use the compatibility information on the replacement-filter page as the primary reference for choosing the correct accessory.

• Check the exact air-purifier model and generation;
• Compare the replacement-filter article number;
• Verify whether you need HEPA, carbon, combination or pre-filtration;
• Compare the stated filtration efficiency of the exact filter variant;
• Follow the appliance instructions for replacement and maintenance.
