Stadler Form Roger & Roger Big Dual Filter H14

The Dual Filter™ is a combination of an H14 HEPA filter and an activated carbon filter. This adsorbs gases such as unpleasant odours, VOCs, tobacco smoke, etc. while the HEPA H14 filter part removes pollutants such as viruses, bacteria, fine dust and pollen from the air. The H14 HEPA filter has a greater density than the HEPA H12 filter, enabling more particles to be removed from the air per air change. The Dual Filter™ will need to be replaced every 8-12 months. Roger big requires 2 Dual Filters™.
