Buff Brite Vacuum Filter Guard Pre-Filter

You place a small weight inside the bottom of the bag before installation. When the vacuum is running, the suction pulls the bag taut against the filter, and the weight lifts to allow airflow; when you turn the vacuum off, the weight drops, causing the bag to collapse and shake off trapped debris.

The Filter Guard is designed to be universal for most wet/dry vacuums, provided your filter is no larger than 11 inches in diameter and 12 inches in length. It is compatible with a wide range of upright, canister, stick, and handheld vacuum styles.

No, the cover is constructed from a breathable, non-stick synthetic fabric specifically engineered to maintain full airflow. By preventing fine dust and debris from clogging the pleats of your primary filter, it actually helps your vacuum maintain optimal suction power for longer periods.

You can use any small, heavy object that fits comfortably in the bottom of the bag, such as a large nut, a bolt, or a small fishing weight. The weight is not included with the product, so you will need to provide your own.

Yes, because the material is a non-stick synthetic fabric, it is easy to clean. You can simply shake off the loose debris or rinse the cover with water and let it air dry before reinstalling it on your filter.
