Disposable Vacuum Cleaner Bags 
A new generation of disposable bags for vacuum cleaners. Unlike simple paper bags, "K&M" are made of a special synthetic material consisting of 4 layers of air filtration.
Prioritization: 
Four layers of air filtration-this improves filtration and air purification quality. 
Due to the features of the material, it increases the power of the vacuum cleaner.
The flexible material allows you to use the entire compartment of the vacuum cleaner bag as efficiently as possible. 
Water-resistant material. 
The possibility of rupture of the pouch during operation is excluded. 
The service life of the bag increases up to 50%.
