SEBO K Series HEPA Service ...

Product details
Part 6431ER is SEBO's HEPA service box for the Airbelt K canister, and the name matters: it is not a bag pack. The box holds eight four layer Ultra bags with sealing caps, one HEPA micro filter and one exhaust filter, which together are the full set of consumables the machine asks for in a year of ordinary use.
The bag wall is built up in four layers, so it holds fine dust further into the fill than single ply paper would and airflow stays more consistent across the bag's life. It still falls off eventually, and past roughly two thirds full an Ultra bag starts pulling suction down gradually enough that owners adjust to it without noticing until a fresh bag goes in.
The two filters are the half people forget. The HEPA micro filter is the final barrier between the bag and the room, and the exhaust filter catches what the motor itself sheds, including trace carbon dust from the motor brushes. Changing bags while leaving both filters in place for years is the most common reason a well kept canister still smells or still exhausts dust.
SEBO lists the box against the Airbelt K range: K1 in its several forms, K2 including the Kombi and Turbo, and K3 including the Premium and Vulcano. As an authorized SEBO dealer we stock the K line alongside the machines, and the sealing caps on these bags are what make a change clean rather than a second dust event.
