Sebo Airbelt K Filter Bags (6629AM / 6629ER) are OEM 8‑count filter bags engineered for SEBO Airbelt K‑series canister vacuums (including K1, K2, K3 models). They feature three-layer electret microfibre construction and top-fill design to maintain airflow even as the bag fills. Each bag includes a self-sealing hygiene cap to lock in dust for clean, allergen-safe disposal. With a capacity of approximately 0.8 gallons (~3 L), they optimize protection for both pre-motor and exhaust microfilters.
