The bag is high grade synthetic, capturing and filtering small dust particles, pollen, dust mites, mite allergens, and cat allergens as small as 1 micron (that is 15 times smaller than the diameter of a human hair). Although the filtration capacity is improved the clogging performance is maintained, thanks to the fine fiber distribution in the material. The s-bag™ anti-allergy has been awarded with the ECARF seal of quality and is TÜV certified.
