Airobot V Filters

The Airobot AIRBOX model name is usually printed on the label on the unit's front panel, or shown in the settings menu of the AIRBOX app. Since Airobot builds compact, demand-controlled heat recovery units with built-in CO2 and humidity sensors, the extract and supply air filter housings are standardized across most generations of the domestic AIRBOX. If the label has worn off over time or is no longer legible, the most reliable approach is to measure the old filter in millimetres (length, width, height) and use those dimensions to find the matching filter in our catalogue.

Most Airobot AIRBOX units run on a two-stage filter set that meets the ISO 16890 standard:

• on the extract side – a coarser G4/M5 class filter
• on the supply side – a finer F7/ePM1 class filter

Because Airobot's sensors continuously adjust airflow based on real-time air quality readings, the filters can clog faster during more intensive periods (parties, cooking, humid weather), so it's worth checking them a bit more often than the usual 3–6 month interval.

Yes. Airobot's demand-controlled algorithm makes its operating decisions based on stable airflow readings, which it interprets together with the CO2 and humidity sensor data. A clogged filter reduces airflow and can force the system to run the fan at a higher speed than actually needed – increasing noise and energy use. Replacing filters on a regular schedule keeps the smart-control logic accurate and lets the unit run on less electricity.

Yes – our ISO 16890 certified compatible filters for Airobot AIRBOX units usually cost noticeably less than the manufacturer's original filters, while matching the same G4/M5 or F7/ePM1 filtration classes and dimensions. Since the filter material and housing size are identical, filtration efficiency and airflow don't suffer – the savings simply come from not paying extra for the original brand name on the packaging.

Many AIRBOX housings technically allow a higher-grade F9 or H13 HEPA-type filter to be used on the supply side instead of the standard F7/ePM1, capturing much finer particles – pollen, ambient pollution or the finest dust. This is worth considering for households with allergy or asthma sufferers. Before ordering such a filter, it's worth checking the pressure drop tolerance of your specific model, since a denser filter material puts a somewhat higher load on the fan.
