Stadler Form Roger Little Dual Filter™ Replacement Filter

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 absorbtion of gases (bad smells, tobacco smoke, formaldehyde, toluene, volatile organic compounds, etc.) while the HEPA filter removes all other airborne particulate. The Dual Filter™ has to be replaced every 8–12 months.
