While you may not be looking for a bag to fall in love with, the new Filtrete^TM vacuum filter bag certainly makes an excellent candidate. 
The bag has a lot more going for it than just good looks - it outperforms every bag in the market. 

The Only Vacuum Bag with 3M^TM Filtrete^TM Air Filter Media

Unlike ordinary paper or lined-paper bags, the Filtrete^TM vacuum filter bag uses a special blend of Filtrete^TM fibers as the filtering material in the bag.  Filtrete media is made of 100% polypropylene fibers that are electrostatically charged to capture small particles.

While ordinary paper bags can pass as much as 50% of the problem particles like dust, pet dander, mold and bacteria back into the air, Filtrete^TM vacuum filter bags capture more than 95% of all micro particles.  So instead of sending particles into the air for you to breathe or to settle on your carpet and furniture, they are trapped in the bag.
