On 2nd thought, I realized that the Central_Filter filters OUTSIDE air, the Portable_Filter filters INSIDE air. Given an efficient and properly designed duct system, running the Central_Filter system long enough should overlap the Portable_Filter system. Nevertheless, the Portable_Filter system is an easy and economical way to do a quick target treatment.
