The Dual Filter™ material guarantees the best cleaning results using a combination of HEPA filter and Carbon Weave technology. Carbon Weave increases the amount of activated carbon exposed to the air for superior removal of odors and harmful gases while the HEPA filter removes all other airborne particulate. The handling is also very simple: just one single filter needs to be replaced after 8–12 months. https://elecena.pl/product/28704600/stadler-form-roger-dual-filter-replacement-h12-hepa-filter 2025-05-16 https://elecena.pl/product/28704600/stadler-form-roger-dual-filter-replacement-h12-hepa-filter 2026-07-02
