Trovac HEPA Bags for Airstream AS300 Canister, 3-Pack

Trovac shapes this three-bag set of HEPA-media dust bags, part TDSACAIR300, for the AS300 canister's dust chamber, and each one seats directly into place. We could not confirm a published capacity figure for this bag from Trovac's catalog, so watch cleaning performance rather than a printed volume when timing changes.

Canisters like the AS300 tend to get run longer between changes than they should simply because the fill window is easy to ignore, but suction falls off well before a bag looks full once the media starts to pack down. Watching cleaning performance rather than the fill window is the more reliable way to know when it is time to swap.

The HEPA media traps fine dust rather than letting it pass through to the exhaust air, so a bag left in too long does double damage: weaker suction while it is running, and fine particulate working its way back out once the media is saturated. Buying in a set of three keeps a machine used regularly from ever running on an empty box in the closet, and storing spares somewhere dry protects the bag paper and HEPA media from losing structure to moisture before the box is even opened.

• Includes: 3 HEPA-media dust bags
• Fits: Airstream AS300 canister vacuum
• Filtration: HEPA media, built to trap fine dust
• Storage: keep spares dry to protect the bag paper and HEPA media

Fold a used bag closed before disposal so the dust already trapped inside stays contained instead of releasing back into the room. Reorder before the current bag is fully spent, especially if the machine sees regular commercial-style use rather than occasional home cleaning, since a canister run daily earns through a set of three far faster than one used for a weekly tidy.
