Carbon air filters for museum and archive preservation applications — long-term trace acid gas, oxidant, and VOC control to protect paper, photographs, textiles, artwork, and sensitive collections. Sub-ppm gas-phase filtration is the spec, which the Koch DuraKleen CPS family targets directly. OdorKleen 600 (KMnO4 alumina for SO2, H2S, ozone) is a strong drop-in option for HVAC slots.
