The top filtration dustbag from Electrolux. Ideal for allergy sufferers, this high grade synthetic bag filters up to 99,9% of household dust, capturing and filtering small dust particles, pollens, spores, dust mites, mite allergens, and cat allergens as small as 1 micron (that is 15 times smaller than the diameter of a human hair). Thanks to its unique patented cardboard the s-bag automatically seals when removed, preventing any spillage and making bag changes cleaner than ever. Very hygienic, it contributes to air purity in your home, therefore protecting your health.
