"Are air cleaners effective for filtering SO2 in my home?
Air cleaners designed to filter particles are not effective in filtering out gases such as SO2. A few air-cleaning device manufacturers advertise equipment that has special absorbent materials and high-efficiency filters that may be effective in removing some gases in a room, including SO2 for some models. However, DOH is not aware of studies that show the effectiveness of these air cleaners and does not have specific recommendations on their use."
