In winter and summer months, when heated or cooled air is recirculated in residential and commercial buildings, odors from cooking, organic compounds, and exhaust can be a huge problem that literally makes people sick.

Before investing in expensive filtering systems, it is worth trying to replace regular HVAC filters withactivated carbon filters.  Tiny pores in the carbon coating of the filter media capture and hold malodorous molecules and remove them from the air--a much better solution that the bad-and-worse combination of fumes masked by even more offensive deodorizers.

Look for filters, like Permatron's odor and fume removing air filters, that use heat setting to bond the carbon coating to the substrate to make sure that the filters will stand up to rinsing and vacuuming.
