Airobot S1/S2 Filters

Check the model name on the unit's rating label. We stock original M5+F7 filter sets for the Airobot L, L5, S1/S2, V3 and V8, and each model takes its own size — for example, the L set measures 269×236×46 mm and the L5 set 305×248×92 mm. If the label has worn off, measure the length, width and depth of your current filters in millimetres and match them against the dimensions on each product page.

Every Airobot filter set we stock — for the L, L5, S1/S2, V3 and V8 — uses the same two-stage combination:

• Extract side — M5 filter
• Supply side — finer F7 (ePM1) filter

Airobot units adjust airflow automatically from their CO2 and humidity readings, so filters can load up faster during busy periods such as parties, cooking or humid weather. Check them a little more often than the usual 3–6 month interval at those times.

Yes. Airobot's demand-controlled algorithm relies on stable airflow readings to interpret its CO2 and humidity sensors correctly. A clogged filter reduces airflow and can cause the system to run at higher fan speeds than necessary, increasing both noise and energy use — replacing filters on schedule keeps the smart control logic accurate.

Yes. All the Airobot filter sets we stock are original M5+F7 sets for the L, L5, S1/S2, V3 and V8, so the size and filter class match what the unit was supplied with. Ordering two or more sets at once gives you a bulk discount, which makes it easy to keep a spare set at home for the next change.

No. The pleated M5 and F7 filters in Airobot units are not designed to be washed or vacuumed. Water and suction damage the filter media and loosen the dust it has already trapped, so a cleaned filter lets more fine particles through and can restrict airflow unevenly. Replace both filters as a set instead.
