Choosing a bag may seem a bit overwhelming as there are many different bags to choose from. First, there are genuine versus generic vacuum bags. If a product is listed as “genuine” it is made by the manufacturer of the vacuum, however, it is typically more expensive. Some people will purchase “genuine” bags in order to satisfy warranty requirements. Products listed as “generic” vacuum bags are made by third-party manufacturers to fit those makes and models.
In addition, there are anti-bacterial genuine & generic vacuum cleaner bags. These bags are designed to prevent the growth of bacteria, germs, and mold. Micro-Lined bags are manufactured with an electrostatic inner lining that catches dust particles such as fleas, dust mites, pollens, and pet dander. These bags are helpful for those people who have sensitive respiratory systems and/or are allergy sufferers. These bags capture as much as 99.7% of particles and allergens.
What you must keep in mind when purchasing a vacuum-cleaner bag is that the quality of the bag does make a difference. The difference in the quality of varying vacuum cleaner bags rests upon what type of material the vacuum bag is made of and how big the holes are in that material. A normal paper vacuum bag is 3 ply or it has three paper layers that constitute the walls of the bag. The general principle is that thicker walls or smaller holes do a better job at keeping the dust particles inside without escaping into the atmosphere.
