Know before you buy
These bags are designed for broad compatibility and fit many systems from brands like Electrolux and Beam, provided they utilize a 2-inch connection diameter. We recommend checking your current bag's cardboard dimensions and hole size against our specifications to ensure a proper seal.
For optimal airflow and suction performance, you should replace the bag once it reaches two-thirds of its capacity. Waiting until the bag is completely full can strain your vacuum motor and reduce overall cleaning efficiency.
These bags are constructed from high-quality paper and feature Ultra Fresh filtration technology. This design is engineered to trap fine dust and debris effectively, which helps prevent allergens from recirculating back into your home's air.
No, they are designed for straightforward, tool-free installation. Simply slide the cardboard collar onto the vacuum's intake port, ensuring a snug fit to maintain the system's suction seal.
Each bag has a 6-gallon capacity, which translates to approximately 22.7 liters of debris storage. This size is standard for most residential central vacuum canisters, offering a balance between frequent replacement and long-term storage.
