Sodium bicarbonate vacuum bag inserts
First Claim
1. A vacuum cleaner bag filter comprising:
- one or more filter walls forming a generally air permeable enclosure having a bag opening therethrough, the one or more filter walls having a working surface area through which air can pass during use;
a flange attached to the one or more filter walls to cover the bag opening, the flange comprising a relatively rigid structure having an air inlet passing into the air permeable enclosure;
a deodorizing sheet attached to an inner surface of the one or more filter walls, the deodorizing sheet comprising;
a first sheet layer, and a plurality of sodium bicarbonate particles operatively associated with the first sheet layer; and
wherein the deodorizing sheet covers less than about 30% of the working surface area.

Abstract
A vacuum cleaner bag filter with one or more filter walls forming a generally air permeable enclosure having a bag opening through it, and a flange attached to the one or more filter walls to cover the bag opening. The filter walls have a working surface area through which air can pass during use, and the flange is a relatively rigid structure having an air inlet passing into the air permeable enclosure. One or more deodorizing sheets are attached to an inner surface of the one or more filter walls. The deodorizing sheets include a first sheet layer, and sodium bicarbonate particles operatively associated with the first sheet layer. The deodorizing sheets may cover less than about 30% of the working surface area, a single deodorizing sheet may be provided, and the deodorizing sheets may be attached to the filter walls by an air impermeable adhesive that covers at least about 5% of the surface area of the deodorizing sheets. Also provided is a vacuum cleaner filter having a filter and a deodorizing sheet attached thereto by an air-impermeable adhesive.

55. A vacuum cleaner filter comprising:
-
a generally air permeable filter having an upstream filter side and a downstream filter side, the filter being adapted to fit into a vacuum cleaner such that the upstream filter side faces an incoming air stream, and downstream filter side is opposite the upstream filter side;
a deodorizing sheet attached to the filter on at least one of the upstream filter side and the downstream filter side, the deodorizing sheet comprising;
a first sheet layer, and a plurality of sodium bicarbonate particles operatively associated with the first sheet layer; and
wherein the deodorizing sheet is attached to the filter by an air impermeable adhesive that covers more than about 5% of the total surface area of the deodorizing sheet. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64)
