Abstract
The present invention relates to a vacuum filter bag comprising a layer containing immobilized odor-retaining particles characterized in that the abrasion loss of said odor-retaining particles caused by an air flow of 90 cm/s through a 200 cm2 specimen of said layer for two hours, measured in accordance with DIN 44956 T2, is 0 to 10% by weight of the total odor-retaining particles present before starting the air flow. The vacuum filter bags of the invention have a high dust holding capacity and an excellent long lasting odor removing effect.
